Tees Seal Photo ID Project

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.    

1 kilometre under the surface: Researching organisms from extreme environment

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

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.
