Stable isotope monitoring of silica budget through Beaufort Sea, the Canadian Arctic Archipelago, Baffin Bay and Labrador Sea: data (sponges) - model comparison

Supervisor: Anne de Vernal (Geotop-UQAM)
Co-supervisors: Claude Hillaire-Marcel (Geotop-UQAM)

Project description:

In this project, investigations on Si concentration in the water and Si-isotope measurements in opal bioproducers (notably sponges)  will be used to document Si budget and fluxes from the Western Arctic  towards the eastern Canadian basins (Baffin Bay & Labrador Sea) will be carried out. Chemical data (Si in water column from Amundsen cruises) will be combined with information on isotopic gradients (30Si) in sponges and possibly diatoms, available through a collaborative endeavour with the Bedford Institute of Oceanography. Modelling aspects will be explored in parallel, possibly in collaboration with the Leibniz Institute for Baltic Sea Research. Expected results should support predictive modelling of the evolution of Si-availability (and thus of primary productivity) in Arctic and Subarctic Canadian marine basins in response to global change stress.
