This proposal is for continuation of Project 030654 funded in FY03. Our
goal is to better understand the extraordinary variability of nutrients
(spatial, interannual and decadal), and factors controlling nearshore
communities and zooplankton and juvenile salmon distributions in the
northern GOA. We propose monitoring nitrate over the shelf and basin.
Underway samples will be collected as part of the NMFS-OCC/GLOBEC salmon
survey in July/August of 2004. This survey includes a transit across
the central GOA and 10 cross-shelf oceanographic and juvenile salmon
transects from Yakutat to Kodiak Island. This will be the broadest
nutrient survey of the northern GOA. Nutrient maps will be used to
support NPZ models and satellite-derived models of nitrate and new
production, to examine mechanisms of nutrient supply such as mixing over
banks and transport up submarine canyons, and to assist resource
management of salmon and other commercially important species.
Purpose:
Conduct a broad survey of nutrient concentrations in summertime in the
northern Gulf of Alaska
