Wind-driven variations in the Atlantic inflow to the Barents Sea

Abstract

Results from a wind-driven homogeneous numerical current model for the Barents Sea are presented. The wind-driven fluctuations in the volume flux through the section between Fugløya and the Bear Island are computed for the period 1970-86. This time series shows a remarkable coincidence with measured temperature anomalies in the Kola section. Reasons for and implications of this connection are discussed. In warm periods there is often low pressure over the central Barents Sea giving an increased Atlantic inflow. In colder periods the opposite effect occurs. It is also suggested that these wind-driven fiuctuations in the current may infiuence the transport of fish larvae. The east-west distribution of 0-group Arcto-Norwegian cod is discussed.
