We’re carrying out fieldwork 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.

Greenland Expedition: July 2018

Our second expedition will take Team ICY-LAB to the fjords of Greenland, near its capital, Nuuk. We will spend a week sampling waters, particles and sediments and using sensors to capture the physical and chemicals variations in this important transition zone from glacial meltwaters to the sea. We are working with the Greenland Institute of Natural Resources.


RRS Discovery Expedition DY081: July -August 2017

During expedition DY081  – the first expedition of the project – 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.

Kate collecting water from a CTD rosette on a previous expedition!

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.
