tellite sensors. The conditions in the Greenland Sea
were not so extreme and the ice extent did not break
the record from 2002 (Polar View, 2007).
The Icelandic Marine Research Institute carries
out quarter-yearly oceanographic expeditions on their
research vessels, Bjarni Sæmundsson and Árni Frið-
riksson. During the Spring cruise to the Denmark
Strait, the conditions were close to average, with tem-
perature being close to average but the salinity slightly
below average (Marine Research Institute, 2007).
