| Description: |
A new study reveals heat transport to the West Spitsbergen Current (WSC) is playing a significant role in the process of Arctic warming. Data collected in the Norwegian and Greenland Seas during the last 20 years reveal considerable changes in the amount of heat transported by the WSC into the Arctic Ocean. The aim of the study was to find out whether the fluctuations in heat input by the WSC have influenced the sea-ice distribution around Svalbard. In fact they do, but oceanic heat transport should nonetheless be regarded as just one of many processes influencing sea-ice behaviour. [Source: Oceanologia]
