Satellites detect abundance of fresh water in the Arctic
ESA satellites show that a large dome of fresh water has been building up in the Arctic Ocean over the last 15 years. A change in wind direction could cause the water to spill into the north Atlantic, cooling Europe.
The results are remarkable: since 2002, the sea surface in the studied area has risen by about 15 cm, and the volume of fresh water has increased by some 8000 cubic km around 10% of all the fresh water in the Arctic Ocean.
Researchers from the Centre for Polar Observation and Modelling (CPOM) at University College London and the UKs National Oceanography Centre used data from ESAs ERS-2 and Envisat satellites to measure sea-surface height over the western Arctic from 1995 to 2010.
The results were published yesterday in the online version of the scientific journal, Nature Geoscience.
