An ice station is the name that scientists give to a collection of tests and measurements that they run on one piece of sea ice. Ice station data is fed into the growing scientific picture of the health of sea ice across the arctic region. Here the Arctic Sunrise is moored to an ice floe to assist scientists in making an ice station. It is from data collected like this that we know the underlying trend of the sea ice is shrinkage and thinning.
