Two PhD Opportunities

Published on by AmbroiseLeave a comment

Our environmental group is delighted to announce 1 fully funded and 1 fees-only funded PhD opportunities. See below and follow the links provided for further information.

Investigation of moorland management practices and carbon dynamics for climate change mitigation (fully-funded)

Peatlands are increasingly being seen as part of nature’s solutions to deal with the environmental challenges of today, from tackling climate change through to flood protection and enhancing biodiversity. However, while all peatlands provide these services, research and conservation efforts have focused largely on deep peats (>40cm depth). Therefore this project will investigate the impact of different management practices on shallow peatland carbon balances. A field campaign will enable multiple sites across the North York Moors to be surveyed and monitored for peat and pore water chemistry, microbial communities and carbon dynamics.

Above and below ground carbon stocks and biotic changes during rewilding

This project will quantify changes in biodiversity, ecosystem function, carbon stocks and their interactions during the initial phases of rewilding. At the primary field site, some 66 experimental fixed plots are set up within formerly agricultural land comprising a variety of arable, improved, and natural grasslands. Rewilding was initiated in 2022, with the cessation of agricultural activities which will be followed by large herbivore re-introduction (eg hardy free-ranging cattle and pigs). The analysis will quantify ecosystem changes in time, against baseline data collected in 2021-2022, and enable an assessment of rewilding contribution notably to net-zero and nature recovery policies.

We anticipate the project to be a unique opportunity to work with a range of collaborators inside and outside academia. We are looking for candidates with a strong interest in combining biodiversity, microbiological and environmental science, to develop novel evidence contributing to the UN decade of ecosystem restoration.

Tees Seal Photo ID Project

Published on by AmbroiseLeave a comment

As part of ongoing work to better understand and monitor seal populations in the Tees and surrounding areas, the Tees Seal Photo ID Project (TSPIP) is a new citizen science initiative giving members of the public (that’s you!) the opportunity to get involved in conservation research. Photo ID involves taking photographs of seals to capture the unique patterns on each seal’s fur. These patterns can be used to identify individual animals and monitor them over time. We can then get a clearer idea on population numbers, see which sites seals prefer and whether this changes over time, learn how far they travel and which other populations they interact with, and even see which seals here in the Tees like to hang out together. The non-invasive nature of photo ID means it’s possible to get all this information without ever having to touch or disturb a seal.

Students at Teesside University are already at work photographing seals and compiling catalogues of individuals which show their markings from different angles, allowing us to efficiently compare new photographs to animals we’ve seen before. There’s only so many places we can be at once though so we’re reaching out to the community to ask you to consider taking photographs of the seals you see and sending these to us. In doing so, you’ll be helping us to expand our catalogues and build upon our understanding of the seals we’ve already logged. At the time of writing, our catalogues contain 132 local seals.

Any picture of a seal could potentially be useful, but the easiest photographs for us to match show the whole left or right side of the animal. If the seal is swimming and you just capture the side of its head, don’t worry – we can use those images too! Photos of seals’ undersides are also helpful as they can allow us to record the sex of the animal.

Want to get involved? Simply send your seal photos to F.Pellie@tees.ac.uk. Please include the date and location the photos were taken in the email.

Want to learn more about the project? This project is coordinated by Freya Pellie, an environmental science PhD student at Teesside University; feel free to drop Freya an email with any queries you may have: F.Pellie@tees.ac.uk.

TSPIP is part of a wider PhD study of the Tees seals, made possible by a studentship funded by Graham Construction and Teesside University.    

New Publication: Proglacial lake expansion and glacier retreat in Arctic Sweden

Published on by AmbroiseLeave a comment

Dr Adrian Dye (Lecturer in Environmental Science, Teesside University) and colleagues report an increase in proglacial lakes in Arctic Sweden as glaciers have retreated. These lakes have grown in size and extent over time, which now form an important store of water (previously unmapped) in mountainous catchments. Some lakes have also enhanced glacier retreat rates… Glacial lakes in the southern region (Sarek) are significantly smaller than those in the northern region (Kebnekaise), so it cannot be assumed that glacial lakes will develop uniformly across an area. More work needs to be done to predict where proglacial lakes are likely to form, particularly where populations currently depend on glaciers for water resources.

1 kilometre under the surface: Researching organisms from extreme environment

Published on by AmbroiseLeave a comment

MSc Microbiology students Orakan Jones and Nathalia Thompson with Drs Paul Dean and Jens Holtvoeth collected brines for extremophile research 1,000m below the surface in the Boulby salt mine.

In October, a team from Teesside University took part in the 10th annual field event on astrobiology, robotics, and planetary exploration (MINAR X), organised by the UKRI Underground Laboratory at the ICL salt mine at Boulby. Dr Jens Holtvoeth was joined by Dr Paul Dean and two microbiology MSc students, Orakan Jones and Nathalia Thompson to travel 1.000 meters down the shaft and underneath the North Sea, together with scientists from the Universities of Edinburgh, York, Manchester, and Newcastle, the California Institute of Technology, and NASA’s Jet Propulsion Laboratory (Pasadena).

The aim of our team was to collect samples of salt and brine for biomarker and DNA analyses to produce a geochemical fingerprint of fossil and living microbial communities and to gain information on cellular adaptation mechanisms of halophile microorganisms to the extreme conditions. This will help to interpret fossil biomarker distributions found in the salt with regard to environmental conditions at the fringes of the evaporating Zechstein Sea about 250 million years ago.

While the team were able to collect brines from a disused part of the mine, aptly named Billingham Bath, the collection of salt samples by coring the salt with sterilised drill bits had to be postponed due to a technical fault of the corer. Thus, the team is looking forward to going down the shaft later this semester, again.

Partnering with Durham Wildlife Trust to address microplastics pollution in the River Wear

Published on by AmbroiseLeave a comment

An update on a previous blog post about our microplastic project in Co Durham, UK.

Environment Group researchers Drs Baldini, Baker, He, Rollason and Scott, along with recent Environmental Science graduate, Zhuhaa Siddiq, recently partnered with Durham Wildlife Trust to investigate microplastics in the River Wear. Fieldwork happened over several weeks in late summer 2021 and involved standing in the river with a microplankton net and flow meter for 20 minutes to collect a known volume of river water for microplastics detection. We sampled water and sediments at five locations along the river Wear from the source (near Wearhead) to the tidal limit (Chester-le-Street). Laboratory analysis revealed a pattern of increasing microplastics in river water downstream from the source until river flow was altered by Durham city weirs. A sharp decrease in microplastics was observed at the furthest downstream site, Chester-le-Street. In sediments, there was a clear pattern of microplastics accumulation downstream of wastewater treatment plants. In summer 2022, Environmental Management research project student, Patrick van Loo Jenner, investigated our hypothesis of microplastics accumulation upstream of weirs in Durham as a precursor to scheduled dredging by the Environment Agency. In March 2022, Dr Baldini presented preliminary findings to a Source to Sea workshop addressing plastics pollution at Durham County Council and in July 2022, submitted a final report to Durham Wildlife Trust. A manuscript of our findings is currently in prep. For more on this successful Teesside University collaboration with local partners see https://www.durhamwt.com/source-sea.

LIMES 2022 – Nijmegen

Published on by GillianLeave a comment

What an amazing week attending the LIMES Congress in Nijmegen. This was my first LIMES congress, so not sure what to expect.. so here is a run down of the events and my thoughts.

Day 1 – so many talks, in so many different rooms, what an outstanding start.. so many free books, I had to rethink my packing and this was day one! One of my highlights was seeing ‘The missing dead’ session about reconstructing the past through digital games play at Roman Vindolanda. I will be bias as a Vindolanda Trustee member but the future thinking was a great talking point with the audience.

Day 2 – first day trip… and I mean all day 7.30 start and back at 8pm… but what a day, when walking round the archaeological sites, Roman Castellum, Meinerswijk, Military practice camps, Uedem and Xanten-Furstenberg, before heading to LVR Archaologischen park Xanten, at the end of the day, the exquisite and beautiful museum was just awe inspiring.

 

Day 3 – The day I had been waiting for, which included the organic riches session… and it didn’t disappoint, chaired by Carol Van Driel-Murray and speakers including Beth Green showed the importance of understanding our artefacts, the discussion came to end with a query about impacts of climate change upon these artefacts, exactly at the right time for us to say a comment about our climate change work at the Roman site of Magna.

There was an evening visit to Valkhof museum, with of course some special LIMES beer

Day 4 – second day trip and this was an absolute highlight for me, the Roman Ship at Castellum Hoge Woerd ‘De Meern 1’  and the wonderful world of Archeon Museum park,  walking through from Mesolithic to the Romans and everything in-between. The hospitality was spectacular, and a delicious BBQ to finish the day. Have to mention the heat, at 34o°C… finding shade and heading inside as often as possible was the order of the day.

Day 5 – Its not the end of the week for us, Fridays talk started with churches in military outposts and a very full session with a talk from CEO Vindolanda Trust – Dr Andrew Birley.

Day 6 – yip still going and it is Saturday, lots of bright early starters to attend the Feeding the Frontier talks, followed by Roman Britian led by Tanja Romankiewicz, as David Breeze said during questions, ‘exceptional’ talk from Tanja – military construction strategies on the Limes: new insights from geoarcheology.

If I didn’t mention your talk, sorry, so much to see, so many pancakes to eat..

Roll on Georgia, what an inclusive, friendly and engaging series of talks and events

Cold Ice in a Warm Windy Bath – Report from a Field Season in the Arctic

Published on by RhysLeave a comment

The GLRETA project captures changes in one of the most dynamic parts of an Arctic mountain environment, by measuring lake temperatures in front of a glacier (proglacial) and the regularity of iceberg calving events (monitored by time lapse cameras) driven by thermal undercutting of the glacier terminus. This has proved to be a challenging environment to undertake field work in, as we have to regularly adapt plans to collect data when the weather windows arrive and hope that icebergs don’t wipe out our temperature sensors in the meantime.

The Arctic summer weather can be very variable in Scandinavia and this year has been no exception. The boulder ‘reinforcements’ of our weather station proved to be successful as it survived the 135 km/h wind gusts largely intact. Sadly our base camp tent didn’t fare so well over the summer and also incurred some substantial damage to the door from some passing fauna. On discovering this at the start of trip 2 we realised that scientific objectives had to be postponed as fixing the tent up before the bad weather arrived was ‘rather critical’. Thankfully after 3 days of floods and high winds we were able to forget about base camp maintenance and get back on with the science.

Flooding wiped out our food storage point and nearly flooded our tent on 2 occasions. 60mm of rain in 12 hours is rather a lot! Photo; A. Dye

Mercifully we were presented with one of the best weather days I can remember in the Arctic and promptly set about compressing 3 days into one rather long one. First on the agenda was a dSLR camera survey to create a digital surface model of the glacier, to calculate how much the ice has lowered from melting during the summer and how much ice has been calved off in icebergs. The glacier front had changed a lot between our visits over the summer, as about 5m wide strip of ice had been calved off across the terminus and the crevasses behind it had widened substantially. Thankfully our time lapse cameras caught these iceberg calving events, along with the changing lake conditions during the summer. Our inflatable kayak mission was successful in retrieving the key lake temperature data sets, which had risen to a maximum of 4oC in late July before steadily cooling from late August. This will provide an important record for understanding how lake conditions and temperature correspond to iceberg calving events, combined with sonar scans of the terminus to understand how the underwater ice front geometry promotes calving.

The recent warm events in Arctic Scandinavia will have enhanced melting of glaciers in the area during the heatwave events, which are predicted to become more frequent with climate change. So we have also been creating digital surface models of other glaciers in the area, to assess how much surface lowering has occurred on these land terminating glaciers. We can then compare the surface lowering of land terminating glaciers to the lake terminating glacier, to assess how they are all responding to recent warm events. We also want to greater understand how contact with a proglacial lake can enhance glacier retreat too and how they are likely to respond to future changes in climate.
