A Field Study of Surface Nutrient Enrichment in the California Current
Abstract
LONG-TERM GOALS. To use the phenomenon of surface enrichment of inorganic nutrients to better understand the cycling of nutrients and materials and physical mixing history in the surface layers of the ocean. OBJECTIVES. The fall 1996 survey cruise of the California Cooperative Oceanic Fisheries Investigations (CalCOFI) was the foundation of a field program to describe in detail the spatial and temporal (diel) variability in the surface enrichment of phosphate, silicate, nitrate and nitrite (Haury et al., 1994, Haury and Shulenberger, In Press). The routine CalCOFI observations provided the environmental context within which the measurements of surface enrichment were made. Numerous ancillary programs provided additional contextual data (e.g. optics, phytoplankton pigments, and nutrient dynamics). The work provides the descriptive understanding of surface nutrient enrichment needed to formulate rational hypotheses on its formation and ecological significance.
