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
