GLOBEC/ICES Working Group on Cod and Climate Change
by Keith Brander
The working group on Cod and Climate Change was established at the 1992
ICES Statutory meeting to carry forward the work begun by the ICES study
group. It will meet for the first time in June 1993 in Lowestoft, U.K.
under the chairmanship of Dr. K. Brander. Terms of reference for the
meeting are as follows:
Expertise in many fields will be needed to tackle this wide-ranging and
ambitious agenda, but the scope is limited to some extent because the
investigation is applied to a single species--cod. Previous reports of
the ICES study group (notably ICES C.M. 1991/G:78) provide useful
summaries of discussions on the application of physical models. Five
questions framed by Ken Brink on the application of physical models in
the Cod and Climate context are as follows:
- review planning and progress of Cod and Climate research;
- review previous study group reports and ongoing regional programs to identify common elements which may serve as unifying themes and enhance comparisons between areas;
- review recent advances in models of global and Atlantic climate variability, consider how these models may be used as boundary conditions for regional models, and plan a specialized workshop on the subject if necessary;
- explore ways of incorporating numerical population models of key species within spatially resolved ecosystem models, in which other species are represented by a relatively small number of aggregated functional groups;
- consider additional opportunities for regional studies and, if appropriate, initiate planning;
- make recommendations, with terms of reference, for future meetings of the working group and/or more specialized workshops, to advance the goals of the Cod and Climate Change program.
It is my impression that we can answer a number of these questions and
will, I hope, be able to make progress at the meeting in identifying and
specifying fruitful areas for modelling and field or experimental
investigation. Scientists wishing to participate in the June 1993

- How sophisticated do the models have to be?
- Is the database adequate for intialization, model driving and evaluation?
- What gaps are there in physics and biology process knowledge?
- Is the cod population predictable? Is it chaotic?
- What phenomena need to be resolved by the models?
