Groundhog explores deep beneath our feet... by Gerry Wildman

To cope with 21st century issues like rapidly expanding cities and demands for natural resources we need clever 21st century solutions. 'Groundhog' is a new digital tool from the BGS which delivers 3D geological models to communities, planners and policy makers. It allows users to understand the issues and solutions that literally lay at their feet. Gerry Wildman, Data and Science Services Manager, explains more...

Geology is a phenomenon that changes at depth. Layers of rock are built up on top of each other over vast quantities of time.  These layers are then subjected to stresses and strains, which fold, fault and deform the ground. Through geological time, older rock layers may be ground down by erosion before younger layers are deposited on top. When considering the geology, it’s important to look not only at the type of the geology you find at the surface, but also how and when this changes at depth. Knowing how these layers change is important in understanding how we can use the ground. For example it can help us to understand where groundwater can flow, where the natural resources are, and what to consider when designing buildings and structures above and below the ground. 

Over the last decade many Geological Surveys across the world, including BGS, have begun to communicate their geological understanding of the ‘subsurface’ through 3D geological models. BGS now has a number of different 3D  geological models ranging from a national resolution ‘fence diagram’ model of the onshore bedrock geology: the GB3D  bedrock model to shallow, local-scale models,  typically for use in ground investigations, groundwater studies and tunnelling projects.

London Geological Model
Recently, BGS has begun releasing data from a selection of their local-scale models in their Groundhog system. Developed by BGS, Groundhog is a tool that is used to deliver geological models over the web. It allows the user to explore the 3D models by creating ‘virtual boreholes’ or ‘virtual sections’.  Groundhog delivers the results straight to the user as pdf reports. Currently 3D models for London, Manchester and part of Suffolk are available in this system, with more planned.

The ethos behind Groundhog is to provide a service that conveys complicated geology in a simple way. As it runs in a web browser, it removes the need for expensive and specialised software, enabling anyone to use the models. But behind the simplicity is some very clever stuff. In creating the underlying models BGS uses a range of methods to capture our geological understanding varying from direct interpretations by geologists to semi-automated modelling involving advanced maths. The methods used depend on the geological situation and how much data is available. Each model takes account of existing BGS experience and data that may include our vast collections of borehole logs, seismic lines and regional geophysical data.

To enable Groundhog to produce virtual boreholes and sections, the models are represented behind the scenes as a stack of 2D elevation grids, each grid representing the stratigraphic base of one geological layer, and a further grid to represent the ground surface (the digital terrain model, DTM).  The grids are then converted to a binary format for use in Groundhog making them much quicker for the drawing tool to access the required data points within them.  A simple database provides an index to the available models and their grid file and fault file layers. By querying a stack of grids for a given X,Y position on a map, Groundhog can create a vertical log through the 3D model.  A series of vertical logs along a specified line can be used to create a cross-section. By considering a collection of vertical logs sampled on a 2D grid with respect to a fixed or DTM-relative elevation value, a horizontal slice can also be produced.

For more information, or to order your own virtual borehole or section, please see our website. Every Wednesday throughout April and May 2015 Groundhog reports are half price, follow #3Dgroundhog on Twitter for more links and info.

Mud, monsters and murders: can geology really help to solve crime? Kirstin Lemon

The recent NI Science Festival was the first of its kind in Northern Ireland and attracted thousands of people to an amazing diversity of science events across the country. This eclectic mix included traditional lectures and demonstrations, and a range of not so traditional such as theatre, comedy, music and film.

One of the less conventional events that took place was called 'How do volcanoes solve crimes?' and was jointly organised by Dr Alastair Ruffell and Dr Jenny McKinley from the Queen's University of Belfast, and Dr Kirstin Lemon from the British Geological Survey. Hosted by the Ulster Museum, this unusual event looked at forensic geology and how it could be used to solve a fictional crime based in the museum itself. A crime scene was created, with the famous 'Minnis Monster', a fossil Ichthyosaur, being stolen and children were asked to see if they could find where the monster was hidden using the mud found on the shoe of the key suspect.

Sediment on wheel arches of cars are often used to place a car
at the scene of a crime. Such evidence was used in the
Soham murder case
What exactly is forensic geology? To put it simply, it is using earth-related material such as minerals, pollen/spores and organic matter as part of a forensic investigation. The concept was probably first used by Sir Arthur Conan Doyle in his Sherlock Holmes books when Sherlock was able to identify where an individual had been using the clay found on their shoe. But forensic geology is not just in fiction as it has been used to solve many crimes including a high profile case that involved locating a body of a murder victim in March 2005 based on soil material believed to be from the body deposition site.

How does forensic geology work? Generally, earth-related materials are collected from a suspect's clothing, footwear, vehicles or dwellings and are used as a comparative material from the crime scene.  Given the sheer amount of potential variables it can be a rather difficult line of evidence to pursue. However, if a number of different analytical techniques are used then the chances of success are much higher. Dr Barry Rawlins, the Soils and Landscape Team Leader with the British Geological Survey has worked on forensic geology and has outlined the key techniques used:

1. XRD or X-Ray Diffraction is used to detect any crystalline or partially crystalline substances in the sample. The advantage of this technique is that it can be used on event the smallest of samples. It is very useful for identifying clay minerals and can help to determine the provenance of rocks and soils.

2. SEM or Scanning Electron Microscopy is used to produce images at a much higher spatial resolution than using a conventional microscope. It also allows for chemical analyses on isolated areas of the specimen and is particularly useful for soil samples.

3. Molecular Organic Matter Signatures can be looked at to identify specific plant communities from the soil sample and thus helping to identify where it came from.

4. Palynology is the study of organic microfossils and their modern counterparts and can be used to identify bedrock or the bedrock that soil samples originate from.

The mineralogy of geological samples was used to identify 
the provenance of aggregate used to bury bodies in a trench 
in Devon. The thin section above is seen under polarised light
A number of these techniques rely on soil samples, all of which formed in the last 10,000 years. Their characteristics are closely related to the parent material from which they formed including underlying bedrock and any Quaternary material such as glacial deposits. Once a soil is identified, its provenance can be determined by combining this with detailed geological knowledge of an area. This ultimately can prove or disprove the location of a crime scene or the presence of a suspect at one.

Forensic geology is being used increasingly to solve crimes, especially those of an environmental nature. Whilst the NI Science Festival event was purely for fun it played a vital role in raising the awareness of this specialist branch of geology, and the role that organisations such as the British Geological Survey play in this.

Given that 2015 is the International Year of Soil and the Year of Mud, then perhaps now is the time to raise the profile of this exciting science.

Isotopes and the bones and teeth of King Richard III ... by Catherine Pennington

Professor Jane Evans (right) and Dr Angela Lamb (left) in their lab in NIGF
Professor Jane Evans (right) and Dr Angela Lamb (left) in their lab in NIGF
Professor Jane Evans and Dr Angela Lamb work in the NERC Isotope Geosciences Facilities (NIGF) at the BGS in Keyworth.  NIGF is one of the largest isotope laboratories in Europe for studying naturally occurring isotopes. 

Jane and Angela front the Science-Based Archaeology programme where they use isotopes to uncover information about the past. 

Some of Jane and Angela’s work is not quite what you might expect.  They have been involved with assisting the police with forensics, identifying fraudulent ceramics, mapping the migratory patterns of fallow deer, understanding how humans have transported chickens around the world and reconstructing past agricultural practices.  More lately, they have been involved with the much reported lifestyle of King Richard III (see below).

But what exactly are isotopes?  How do we use them to date rocks? What can isotopes in teeth and bones tell us?  Jane explains in this video:

King Richard III's teeth

King Richard III died at the Battle of Bosworth in 1485 and teams from the University of Leicester and the Richard III Society uncovered this warrior king’s remains under a council car park in 2012.  The skeleton was then tested to confirm his identity and to try to reveal how he died.  Jane and Angela were asked to find out more about his lifestyle and movements.  They were given a pre-molar tooth and small pieces of femur and rib bone as these all form at different stages of life, giving a range of information across the king’s lifetime as Angela explains:
By looking at the oxygen and strontium isotopes in his bones and teeth we were able to look at where he lived through his life. The teeth, which form in childhood, confirmed that Richard had moved from Fotheringay castle in eastern England by the time he was seven and that he had moved back to eastern England as an adolescent or young adult.  We then looked at the dietary isotopes, carbon and nitrogen, to look at how his diet changed throughout his life
One of the most important findings from their isotope analysis was that there were marked changes in his diet when Richard became king in 1483; he began eating a diet only the highest aristocracy could afford.  This included freshwater fish and birds, such as swans, crane, heron and egret.  In addition, the bone chemistry suggested he was drinking more wine during his short reign as King and reinforces the idea that food and drink were strongly linked to social status in Medieval England. 

You can read more about the work Angela and Jane did by reading their paper:

Dr Angela Lamb is a Research Scientist within the NERC Isotope Geosciences Facilities.

Both work within the Centre for Environmental Geochemistry, a joint venture between BGS and the University of Nottingham.

Why learn good Science Communication?... by Jonathan Dean

Our scientists never stop striving to improve their understanding of the world around them. Equally they never stop learning new ways to better communicate their work and discoveries to the wider world. One such scientist is Jonathan Dean, a Postdoctoral Research Assistant at BGS, who's just back from a 2 day public engagement course run by NERC. Here Jonathan reflects on the importance of good science communication and the skills learnt on the NERC Engaging the Public with your Research training course...

Public engagement – letting non-scientists know what science we’re doing with their taxes – is important. Many people are interested in finding out, for example, when humans evolved from apes, what caused an extreme flooding event and if there is life on Mars, but they are going to be left in the dark unless they trawl through academic journals on their evening commute (unlikely) or unless we make an effort to reach them. We can get our message out to the public in a variety of ways, for example via the media, in blogs on our websites and at talks in schools. Lots of our work could benefit society – we might have discovered mineral deposits that could stimulate economic growth, found a way of reducing the pollution emitted from cars or established how changes in solar activity influence the Earth’s climate. But if policy-makers don’t know what we’ve found, then policy can’t be changed and our findings might go to waste.

NERC - the parent body of BGS
We began our training course with instruction from a BBC News science reporter on how to write a good press release. We found that they are written the opposite way round to how we’d write up our results for a peer-reviewed journal – the snappy summary of the findings, which would be in the conclusion of a paper, should come first, followed by more detail about why it is important and how we carried out the research. Unless their imagination is captured within the first few seconds, journalists will stop reading and move onto the next press release, and our research will never find it onto the Today programme or into The Times (other media outlets do exist).

We then learnt about how to design public engagement activities, such as talks in school or in pubs, before moving onto radio interviews. While listening to the sound of your own voice played-back in front of everyone is never enjoyable, our practice interviews were really useful. We realised the importance of avoiding jargon (for example using the word ‘results’ rather than ‘data’) and in coming across enthusiastic – making yourself smile during the interview helps this! Finally, we had the chance to produce our own media, by making a podcast. I played the role of a radio presenter interviewing two people about fracking.

The course takes place in the NERC office in Swindon 9 times a year and can be attended by anyone who works for NERC or holds a NERC grant, including NERC PhD students and PDRAs. I would thoroughly recommend it as a really useful and enjoyable course that gives you new ideas for engaging with the public and more confidence when dealing with the media.

Welcome to Iceland fieldwork from above... by Jez Everest

Jez Everest established our Virkisjökull Glacier Observatory in 2009, and new equipment has been installed each year to monitor climate, ice dynamics, landscape change, hydrology and groundwater. Today, with the snow keeping them close to camp, Jez has put together a little intro video with the new hexacopter footage...

The BGS Glacier Project machine grinds into gear once more, boldly going where none have gone before. Well almost. This time the team consists of a mixture of BGS and GSNI staff, plus staff and MSc and MRes students from Dundee and Lancaster Universities, here for 10 days with a huge range of research activities to complete.

Atypically the trip started with delays caused by a late shipment of equipment from the UK. Who would have thought it was so hard to transport LiPo batteries between countries? However the blue roof of Austurbaer at Svinafell hove into view on Wednesday evening, bathed in sunshine. Thursday was spent steam drilling holes in the glacier to discover meltwater pathways along faults and thrusts, sampling various water sources for sulphur isotopes, and testing the hexacopter which will carry our thermal imaging kit to be used on the trip… more on this hopefully later in the week. There was still a bit of time for Paul and Ali to go for a run before dinner, and for me to do some video using the quadcopter.

Unfortunately today has seen bucket loads of snow, hiding crevasses on the glacier, and blanketing the ground, obscuring features and their thermal properties from the two drone helicopters. The only work possible has been to download all the groundwater borehole data, test various bits of kit, and piece together a short intro video for your enjoyment. The Dundee students have also had to do a series of presentations for their MSc coursework, via the internet to their classmates and staff back at home. So still plenty to do, despite the Christmassy weather outside.

Hopefully we will be able to get back on the ice, and get all our birds in the air tomorrow, really getting the research programme underway.
I’ll keep you posted

The St. Patrick’s Day Geomagnetic Storm... by Sarah Reay

On the 17th March 2015 the Earth experienced a strong geomagnetic storm. This ‘St. Patrick’s Day storm’ was the largest storm in over 10 years, and the largest of the current solar cycle! Sarah Reay, from the BGS Geomagnetism team, expands on the science behind the solar storm...

So what happened?

The storm began at 04:46 UT on the 17th March 2015 when a shock in the solar wind (a stream of charged particles emanating from the Sun) hit the Earth’s magnetic field signalling the arrival of a coronal mass ejection (CME). A CME is a massive burst of charged gas and magnetic field ejected from the Sun’s corona which is carried away from the Sun by the solar wind. The sunspot region responsible for the CME was centrally placed on the solar disc and so the Earth was directly in the line of fire! This CME travelled quickly towards Earth arriving earlier than space weather forecasters had predicted, taking us a little by surprise.

BGS magnetometers, which measure the variations in the strength and direction of the Earth’s magnetic field, recorded the impact of the CME. We observed a rapid variation in the magnetic field signalling the start of the geomagnetic storm. At Eskdalemuir observatory in the Scottish Borders the rapid variation was approximately a fifth of a degree in compass variation (i.e. declination). 

A magnetogram showing the variation in the compass variation (in degrees west of true north) for the three UK magnetic observatories the 17th – 18th March 2015. You can see the shock arrival and storm commencement followed by larger variations later in the day
Shortly after the shock impact those on the night-side of the Earth were treated to a spectacular auroral display. There were various sightings reported across North America, and more unusually, some great sightings of the aurora australis in New Zealand (New Zealand is of similar geomagnetic latitude to the south of UK). If it had been dark, we should certainly have seen the northern lights across the UK. However our night-time was many hours away. The question everyone was asking was how long would the storm last and how strong would it be?

Why the storm was so strong?

One of the main factors that influence how big a magnetic storm will be is the direction and strength of the interplanetary magnetic field (IMF). That is, the magnetic field carried in the solar wind. If this turns southwards it allows much more energy into the Earth’s magnetic field. If it turns northwards it can effectively ‘shut down’ a magnetic storm. This key aspect is, unfortunately, not one space weather forecasters can predict well in advance so it is difficult to know what nature a storm may have in the coming hours.

Solar wind conditions measure by the ACE satellite. The top trace (red) shows IMF turning southward for extended period of time. Orange, yellow and green traces show the change in density, speed and temperature and the CME arrived.
Remarkably in this case the IMF went strongly southwards for well over 12 hours allowing a lot of energy to flow into the Earth’s magnetic field. This produced a major magnetic storm. The Space Weather Prediction Centre (run by NOAA in the USA) has five defined levels of geomagnetic storm activity from G1 to G5 with G5 being the most severe. This storm, at its peak, reached G4 level for several hours. G4 levels were seen globally between 12:00 – 18:00 UT and again between 21:00 – 00:00 UT on the 17th March 2015. Space weather forecasters in BGS and Met Office continually monitored the situation throughout the day and consulted with each other as the storm progressed.

A northern light show

When a geomagnetic storm is in progress the auroral ovals, usually located near the Arctic and Antarctic circles, broaden and move out towards the equator. That is why during a magnetic storm the aurora can be seen more easily in the UK.

As the geomagnetic storm rumbled on throughout the St Patrick’s Day more people around the world were treated to a spectacular auroral display - that is, if they were lucky enough to find a gap in the clouds. Unfortunately for the UK many places were covered in thick cloud or fog so missed out on this event. However many more were lucky and sightings were reported across Scotland, Northern Ireland, Wales and the parts of England even as far south as Hampshire and Sussex. In Europe, aurora was seen as far south as Germany and The Netherlands.

The day after the solar wind conditions remained heightened and geomagnetic activity, whilst no longer at the peak of activity, continued at a moderate storm level throughout the 18th March. Once again parts of the UK reported aurora sightings but these were mainly confined to Scotland.

So how big was this storm?

One way of measuring how large a magnetic storm is by a type geomagnetic index – the Ap index. This is measure of global geomagnetic disturbance. When Ap is greater than 100 (out of maximum of 400) this is classed as a ‘severe storm’ (severe in this case refers to the magnitude of the storm rather than a comment on the possible impact). The St Patrick’s Day storm had an estimated daily Ap of 108. This is the largest magnetic storm of the current solar cycle (which began in 2008). We need to go back 10 years to September 2005 for the last storm with an Ap >100. The last magnetic storm which was bigger than the St Patrick’s Day storm was in November 2004, almost 11 years ago!

Chart showing all the major magnetic storm with a daily Ap greater than 100 since 1980. Notice the large 10-year gap before the St. Patrick’s day storm.

Is there an environmental link to esophageal cancer in Tanzania?... by Michael Watts

Scientists from the Centre for Environmental Geochemistry are helping health organisations understand why esophageal cancer is localised within specific areas of the African Rift Valley. Whilst various causal factors are now under investigation, such as high-strength ‘kill me quick’ alcohol consumption or hot tea drinking, it is difficult to fully explain the localised nature of the burden. Here Dr Michael Watts outlines why soil around Mount Kilimanjaro could unearth some answers…

Dr Valerie McCormack from the International Agency for Research on Cancer (IARC, part of the World Health Organisation) has studied the high prevalence of esophageal cancer in the Rift Valley and identified a particularly localised incidence of cases in the Mount Kilimanjaro area of Tanzania. A hypothesis was presented that an environmental factor, such as exposure to potentially harmful elements or organics (e.g. polycyclic aromatic hydrocarbons, PAHs, from wood fires) or deficiency of essential micronutrients (e.g. zinc) that diminishes the body’s ability to recover from or buffer an event that may cause cell damage, could be contributing to this.

Kilimanjaro district
This is where the skills of the inorganic geochemistry team come in. With support from the Centre for Environmental Geochemistry (CEG) and BGS Global, the BGS Inorganic Geochemistry team assisted IARC-WHO and the Kilimanjaro Christian Medical Centre (KCMC) in designing and undertaking a detailed survey of soil, water and crop samples in the Kilimanjaro district.

Children from Masame
Our primary aim was to link geochemistry and crop data with areas in which esophageal cancer cases were prevalent.  In addition, the data will demonstrate a spatial understanding of the geochemistry of the differing climatic zones and food production areas around Mount Kilimanjaro and to provide an indication of micronutrient composition or presence of potentially harmful elements. 

This increased understanding of the soil and crops in Kilimanjaro will improve baseline evidence for a differing climatic zone compared to previous work in Sub-Saharan Africa (previous blogs), to inform future experimentation of agricultural methods that could improve soil-crop transfer of micronutrients for onward health benefits.

We also provided training to local counterparts from KCMC and the Ministry of Agriculture Kilimanjaro District Extension Office in the collection of environmental samples, recording of field data for quality assurance / data management and onward presentation in GIS maps for agricultural planning tools. It is a privilege to be able to help where our skills are needed most and it’s clear these strong working relationships will bring benefits to local populations and the wider science community. We see clear opportunities for future collaboration with all of the partners we worked with in Tanzania, including the Regional Area Secretariat from the Prime Minister’s Office.

Rombo Mkuu
In fact the CEG has already partnered again with IARC-WHO (the project leaders) on a recently gained grant from the US National Cancer Institute to study a similarly high-localised prevalence of esophageal cancer in the Eldoret region of Kenya.  Such work involves the cross-disciplinary collaboration of epidemiologists, medics, health practitioners, biostatisticians, geochemists, farmers and local agricultural extension workers and commences 2015 to 2017. Watch out for future blogs and see all our research via our CEG website.

Records on the move... by Lorna Stewart

Last pallet being loaded on the lorry in Edinburgh
As we've reported here before our two offices in Scotland are being united at one single site in Edinburgh. In the Spring of 2016 The Lyell Centre will be the new home of BGS in Scotland and preparations are already well underway. Here Lorna Stewart, Records Manager, tells us about the latest activity...

Following months of careful indexing and scanning the first delivery of Records from Murchison House left Edinburgh on Monday 9th February for relocation to Keyworth.
Records staff still smiling after a hard
day of re-shelving the records in
their new home
For the past 18 months the Records Team at BGS Murchison House have been preparing the records for transfer, some collections have been scanned and all have been  meticulously indexed to ensure that they remain accessible. Where there is no existing scanned image a Scan on Demand Service will be available. Records and  Reprographics staff at BGS Keyworth had in the meantime prepared the top floor of the Publication Store (V block) to receive the material.

Each folder and container is barcoded and is associated with the barcoded shelf location at Keyworth to make sure that they can be quickly and accurately retrieved when requested.
The respective Records Teams managed the physical handling at either end of the operation; happily the weather was on our side and all 49 pallets were unloaded and undercover by the end of Tuesday morning.

Records happy in their new home
By Wednesday afternoon all of the 3,000 boxes and files had been shelved and the database updated with their new locations. Massive thanks is due to all staff who helped in the process, it bodes very well for the next 12 months or more of work ahead.


[The BGS Communications team have also just published the latest YouTube update from The Lyell Centre site, see below.  

Heriot-Watt have also announced on their website some major donations to the Lyell Centre development from two leading philanthropic charities.

A new way to knowledge exchange... by Sophie Wood

Claire Shelley on her soapbox (that's an
imaginary box, no risk assessment needed)
The BGS Informatics and BGS Environmental Modelling teams are an eclectic mix of highly skilled staff from our offices in Keyworth, Edinburgh and Cardiff. To share their different talents, skills, ideas and projects they host an annual interactive team Information Workshop. Here Sophie Wood tells us more about the activities and how innovative days like this benefit everyone…

Thursday 5th Feb saw the second Informatics and Environmental Modelling Information Workshop held at Keyworth in both the conference suite and the communal William Smith Building lower ground floor. Half a day was given to finding out and learning about many of the different projects  currently ongoing within the two directorates and the event had 4 main sections.

1: a round-up and vision for the year ahead from the directors Kate Royse and Matt Harrison followed by a quick resumé from each of the team leaders with lots of interesting facts and figures about the projects and the teams themselves. Edinburgh joined us by video-link which was good to see, even though some of the transmission was lost for a few minutes due to technical difficulties. The slides from all of these presentations are available to all BGS staff via our Intranet.
2: the Poster Gallery with 14 posters displayed work by both Keyworth and Edinburgh staff adding interest and new focal points in the Keyworth atrium. Topics covered included Mining Hazard in Great Britain, Domesday Project, MyVolcano, G-Base, DECC data and MAREMAP to name but a few.
3: Soapbox style presentations including topics ranging from Data Ingestion, Data Scientists to BiG data were delivered from our version of Hyde Park’s Speakers Corner with a sparkling tree and tweeting fluffy bird dive-bombing any speaker who dared to overrun their time slot – which happened a lot but most of the bird strikes missed !
4: the Merry-Go-Round session was a most successful part where demo’s of 10 minutes duration were given throughout an hour and half by staff at their desks talking to groups no larger than 10 people.

The final wrap up session by Matt and Kate with questions
from the floor - not to be mistaken for the soapbox!
This year a very diverse range of projects were on show and most of the attendees lunchtime was taken up choosing which to go to out of an impressive 17.

The event was well attended with 80+ individuals and although it was devised for just the 2 directorates to learn who and what are involved in them, the lunchtime Poster Gallery viewing and Soapbox presentations were open to the whole site. Nice to see lots of staff coming to check it out.

With prizes for best Poster, Soapbox and Merry-Go-Round demo’s it was a fun way to bring the informative event to a close. Much was learnt during the day through a friendly and informal environment especially the Merry-Go-Round where in small groups around someone’s desk people felt at ease to ask questions and not be intimidated by a large conference room setting.

Jellyfish are dish of the day at EnviroHack 2015... by Rachel Heaven

EnviroHack 2015 ©
Is open access data helping to solve environmental problems? Yes, but only with the innovative thinking and skills of people from a wide range of scientific and engineering disciplines. Rachel Heaven, Stephanie Bricker, Anubha Singh may have different expertise within BGS but one thing they all share is wanting to put data to it's very best use. Here they tell us more about their experience (and jellyfish) at this years NERC EnviroHack...

So it turns out that jellyfish can wreak havoc for power stations by getting sucked into and clogging up the water supply intake pipes – who knew? (Don’t believe me? The headline in National Geographic read Jellyfish Invasion Shuts Down Nuclear Reactor). A system to identify and track likely jellyfish hotspots using atmospheric and oceanographic data was just one of the great ideas we saw developed at NERC’s EnviroHack 2015 last weekend.

EnviroHack 2015 is a data jam. In essence you put a bunch of enthusiastic data scientists, designers and software engineers in front of a wealth of openly accessible environmental data (atmospheric, meteorological, hydrological, ecological, geological…), feeding them some pizzas (and perhaps a little beer), letting them cook for 2 days and then hopefully seeing some innovative application prototypes that could address important environmental challenges such as environmental change, resilience to environmental hazards and use of natural resources.

The event was hosted at Digital Catapult, in what is being branded the Knowledge Quarter in London. We were on a 9th floor office opposite the British Library, giving fabulous views over St Pancras Station, and across the London skyline. 

After admiring the view and a few talks from the event partners - which in addition to NERC and Digital Catapult included the Knowledge Transfer Network, Microsoft Research and Red Ninja Studios - we had a quick brainstorming session and then were encouraged to give lightning talks to pitch our ideas. Some of these had clearly been planned in advance and were well thought out with a good knowledge of the available data...others were loose ideas sparked off that morning that morphed and took shape as the project teams were formed around them.

The ideas that we pitched and worked on (food_chain and Energy Cast) definitely fell in the latter category, but the self-organising teams managed to do an amazing amount in a short time to present prototype solutions by the end of day 2.

The jellyfish hackers on team JellyStrike led by Centre for Ecology and Hydrology's (CEH) Tom Redd were catch of the day taking overall first prize and winning development support for the next 100 days, but - as at a school sports day - most teams managed to come away with at least one prize (best 2D visualisation, best mobile app etc).

Some of the other ideas were:
  • food_chain - connecting surplus produce e.g. from allotments, to food charities and businesses to reduce food waste.
  • Energy Cast - a weather-forecast and machine learning informed green energy app to help match domestic energy supply with energy consumption.
  • ShowMeTheNature - putting people in touch with green space, an app to rate the quality of the green space near to you using the metrics of your choice, with user-feedback.
  • CHARM - a self-learning data system to allow users to enrich environmental data by adding annotations, use cases and key metrics to make more sense of our data-rich world.

Why no geological data ? Well, independently of this event BGS had already started implementing ideas based on the same principles as EnviroHack. For example:
  • aligning our geochemical sampling datasets with those of CEH and British Oceanographic Data Centre (BODC) so that chemical pollutants can be tracked from source to sea
  • aggregating worldwide soil data in the BGS mySoil app
  • optimising the use of national scale datasets in Natural Capital Mapping (see the  CEH/BGS academic paper here)

The original idea for Energy Cast could have included various datasets available for assessment of Ground Source Heat Pump potential, but the hackers preferred the wow factor of presenting dynamic datasets (and who can blame them with an Oculus Rift virtual reality headset to compete for?!). It’s true many of BGS’s open datasets describing the subsurface are static, but they can provide the framework that determines the movement of fluids underground and are so important for many of today’s critical issues.  As an organisation we are increasingly dealing with time series monitoring data and outputs from process models, and we need to work on making all those open and accessible where appropriate so that other developers and data scientists can make use of them.

We also learnt a lot about how other people approach and solve software problems, got ideas about how we might apply machine learning, made a lot of good contacts and had a load of fun. 

What did the organisers learn ? That even though lots of datasets are available it still took them a lot of time and effort to find out what was out there and how to get hold of it, and even then the size and complexity of the data can inhibit its usage. BGS was held up as a great example of making data open and accessible but we still have far to go and it’s something we are continuously improving.
