Mesoscale eddies move through
the ocean carrying physical, biological, and chemical
anomalies. They translate over space scales of hundreds
to thousands of kilometers and exist for periods lasting
from months to years. Eddies are found throughout the
North Pacific Ocean in association with strong boundary
currents like the Kuroshio and Oyashio and the Alaskan
Stream, and also with North Pacific eastern boundary
currents like the California and Alaska Currents. They
are also prevalent in marginal seas. Generation and
evolution of eddies are thought to be related to the
shear instability of boundary currents like the Kuroshio,
and topographic features in the California and Alaska
Currents. Mesoscale eddies affect the structure of marine
plankton in various ways. Horizontal advection and vertical
mixing by eddies contribute to the generation of high
chlorophyll concentration off the coast. They draw shelf
water containing nutrients and planktons into the deep
offshore waters. Mesoscale eddies are also important
for survival of larvae. Eddy pumping also plays a role
in episodic nutrient injections into the photic zone
resulting in enhanced primary production inside the
eddy for cyclonic eddies. For anticyclonic eddies, ageostrophic
upwelling and divergent Ekman pumping due to winds over
the eddies yield upwelling within the eddy. This workshop
will address: 1) dynamical characteristics of mesoscale
eddies in different parts of PICES domain, focusing
on their similarity and difference; 2) influences of
eddies in constituting the dominant physical forcing
on the ecosystems; and 3) expected future eddy activities
and their possible impacts on North Pacific ecosystems.
