Session
8. POC/BIO Topic Session
Anthropogenic perturbations of the carbon cycle and their impacts in the
North Pacific
Co-Convenors: James
Christian (Canada) and Toshiro Saino (Japan)
Accumulation of anthropogenic carbon and
associated changes in ocean chemistry ("ocean acidification")
affect all of the world’s oceans. Anthropogenic CO2
has multiple feedbacks to ocean chemistry and biology, such
as reduction of calcification, shifts in phytoplankton species
composition, and dissolution of particulate or sedimentary carbonates.
The carbon system can also be affected by other anthropogenic
factors such as changes in river flow and aeolian dust deposition.
Carbon and nutrient biogeochemistry will be affected both directly
and indirectly by ocean acidification. This session invites
papers that address the biogeochemistry of anthropogenic carbon
(processes controlling its distribution, processes by which
it alters ocean chemistry), other anthropogenic impacts on carbon
and nutrient cycles, acidification impacts on marine biota,
and feedbacks among these.
