Fieldwork

RRS Discovery Expedition DY081: July -August 2017

The approach will be to capture the whole silicon cycle system in areas of marked environmental change using careful field sampling strategies – with research expeditions to coastal Greenland and the open ocean Labrador Sea – coupled with cutting-edge analytical methods.

During expedition DY081 we will be collecting samples for ICY-LAB from locations within the Labrador Sea in the NW Atlantic, including seamounts that are influenced by different oceanic currents, and the Greenland shelf. We will collect samples of seawater, particles, sediments and biological specimens, all the way from surface waters to within the seafloor sediments.

From the RRS Discovery, we will deploy Conductivity Temperature Depth (CTD) rosettes to collect physical oceanographic data and water samples, Stand Alone Pumps (SAPs) to collect particles within the water, and sediment corers. Finally, we will use a Remotely Operated Vehicle (ROV) to collect water, sediment and biological samples from near the seafloor.  The international expedition team is multi-disciplinary, including geochemists, physical oceanographers, palaeoceanographers, engineers, and biologists – some specialising in algae and some specialising in seafloor dwelling creatures.
