This
workshop will provide an opportunity for those keenly interested
in "how data on zooplankton and krill can be used to better
understand and forecast the impacts of climate change on fisheries"
to discuss the topic in an informal workshop atmosphere. It
is expected that the workshop will demonstrate explicitly how
information on zooplankton and krill contribute to better understanding
of linkages between physics and fish. Furthermore, the workshop
will likely generate novel ideas that will add to the open discussions
during the Symposium itself.
It is anticipated
that the workshop will produce a white paper that summarizes
ongoing research activities as well as publications which link
climate change to fisheries through changes in the food web
in a variety of ecosystems – coastal, oceanic, upwelling, Arctic,
and Antarctic. This will be a foundation document that shows
where we are now and where we want to be in the future. It would
also produce a set of recommendations for how we might move
forward in our quest to better understand the mechanisms that
link physics and fish through food chain interactions. Such
a white paper could be found acceptable for publication, after
peer review, in the "Horizons" section of the Journal
of Plankton Research.
