Production and Fate of Organic C and N in the Wind Driven Coastal
Ocean off Oregon

P A Wheeler

The most immediate products of primary production in coastal
upwelling systems are particulate and dissolved organic carbon
and nitrogen. During The Coastal Ocean Advances in Shelf Transport
(COAST) project we collected discrete water samples from transects
across a narrow shelf (CH line) and across a broad shelf (Heceta
Bank) in May and August 2001. Analyses included inorganic nutrients,
particulate organic carbon (POC), particulate nitrogen (PON),
dissolved organic carbon (DOC) and dissolved organic nitrogen
(DON). The four pools of organic material comprise most of the
organic carbon and nitrogen in this coastal system. The partitioning
of N and C will be presented and analyzed to determine:1) What
fraction of incoming nitrate is assimilated and accumulated as PON
and DON?, 2) What forms and how much organic nitrogen are exported
from the shelf? 3) What forms and how much organic carbon is exported
from the shelf? and 4) How do the ecosystems of the narrow and broad
shelf differ with respect to nutrient dynamics and C and N cycling?
