Workshop 1 (BIO Topic)
Natural supplies of iron to the North Pacific and linkages between iron
supply and ecosystem responses
Co-Sponsored by SOLAS
Co-Convenors:
Fei Chai (U.S.A.), William R. Crawford (Canada) and Shigenobu
Takeda (Japan)
In the subarctic North Pacific Ocean,
iron plays a central role in regulating phytoplankton productivity
and pelagic ecosystem structure. There are several processes
that supply iron from land, shelf sediment and deep waters
to the upper ocean. The goal of this workshop is to examine
mechanisms of these iron supply processes, including atmospheric
deposition of mineral aerosols and combustion substances,
lateral transport of coastal iron-enriched waters by eddies
and boundary currents, and deep vertical mixing during winter
or by strong tidal currents at narrow straits. Such knowledge
will be used to identify key biogeochemical pathways that
should be introduced into the ecosystem models and to plan
international scientific programs for better understanding
of marine ecosystem responses to changing iron supplies
in the North Pacific.
