Ocean Modules V8 ROV Conquers Both Poles

Four years after visiting the Antarctic with the Aurora Australis Sea Ice Physics and Ecosystem Experiment the Ocean Modules V8 Sii ROV has now also visited the North Pole, to measure sun light underneath the sea ice.

Marcel Nicolaus and his colleagues from the Alfred Wegener Institute for Polar and Marine Research are currently measuring how much light reaches the ocean under the sea ice. For their measurements, they are using light sensors, spectral radiometers to measure the light directly, an altimeter to measure the distance to the ice and the ice thickness, and a video camera to document the dives and the ice conditions. The ROV, known to the crew as Alfred, has been doing a great job and was happy to reach the North Pole on the 22nd of August 2011.
