DR. TRACY SHIMMIELD
Scottish Association for Marine Science
Dr Shimmield also has a strong background in radiochemistry, having conducted a number of environmental research using radionuclides as tracers for marine processes.
Her present research interests include:
- The investigation of pollutant sources and transport pathways to the Arctic
- The
development and use of palaeoceanographic proxies within fjordic sediments
to investigate high resolution environmental change over the last 10,000
years and the sequestration and
remineralisation of carbon within marine sediments.
The work undertaken in the Arctic has been funded by NERC through SAMS Northern Seas Programme (www.sams.ac.uk) and the EU through its Large Scale Facilities programme. This has allowed Dr Shimmield to be PI or Co-PI on NERC, EU and commercially funded research.
What will the expedition attempt to do?
Any sediment on the ice is blown in on winds and deposited on the ice but it will only be deposited on the seabed after the ice melts which could be a long way from where it was first deposited (ie moving ice sheets).
The team will attempt to bring back about 0.2-0.5 grams of dirt samples. So eyes open for dirt!
