TASC: The Role of Cross Shelf Exchange Processes in Controlling Seasonal Population Dynamics

The primary objective of this subtask of the TASC programme, is to examine the role of NSDW in a) facilitation colonization of the temperate northeast Atlantic rim ecosystem by C. finmarchicus which is essentially a sub-Arctic species in terms of its global distribution and b) potentially providing a link or teleconnection between the various ecosystems thereby leading to a degree of synchrony in their responses to climatic forcing.

As part of this programme, investigators were researching the following topics: 1) Overwintering, across shelf advection and spring spawning in Shetland-Faroe and southeastern Icelandic waters 2) Overwintering, advection and spring spawning south and southwest of Iceland 3) Analysis of historical time series data 4) Generation pattern and switching along the Norwegian midshelf 5) Modelling the cross-shelf dispersal of Calanus
