This two-year, $250,811 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research examining the biogeochemical importance of marine particles in the northern Gulf of Alaska. The University of Alaska Fairbanks will investigate the mechanistic relationships between marine nutrient uptake, particle production, and export processes through field work, data analysis, and cross-site collaboration. Core efforts include collecting and integrating new datasets on biogenic silica standing stocks and tracers, productivity via silica production and nutrient uptake measurements, and export data on carbon, nitrogen, biogenic silica, trace elements, and isotopes. Data synthesis will utilize Lagrangian tracer simulations, linear inverse ecosystem modeling, and biogeochemical parameter estimation. Findings seek to improve estimates of the biological carbon pump within this high-latitude coastal region important for fisheries, addressing priority science questions around quantifying the ocean's role in the carbon cycle and export efficiency to deep ocean waters.
