Abstract: The goal of this project 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 Gulf of Alaska. The project will monitor nitrate over the shelf and basin. Underway samples will be collected as part of the NMFS-OCC/GLOBEC salmon survey in July/August of 2003 and 2004. This survey includes a transit across the central gulf and ten cross-shelf oceanographic and juvenile salmon transects from Yakutat to Kodiak Island. This will be the broadest nutrient survey of the northern gulf. Nutrient maps will be used to support NPZ (nutrient/phytoplankton/zooplankton) 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. GEM funding in 2003 is crucial as this is GLOBEC's final intensive field season.
