The Joint Global Ocean Flux Study in the North Pacific

This volume of DSR II is dedicated to the Joint Global Ocean Flux Study (JGOFS) North Pacific Process Study (NPPS), coordinated by the JGOFS North Pacific Task Team. Following the studies conducted by Canadian JGOFS in the eastern subarctic Pacific, the JGOFS NPPS focused mainly on the western subarctic Pacific. The goals of the JGOFS NPPS were to quantify CO2 drawdown by physical and biological pumps in the northern North Pacific by identifying and studying the regional, seasonal to inter-annual variations of the key processes, and to understand their regulating mechanisms. The NPPS was composed mainly of Japanese programs conducting extensive surveys, intensive biogeochemical process studies, time-series observations at station KNOT at 44°N, 155°E, ocean color satellite observations, and modeling. A total of 27 papers included in this volume cover CO2 intrusion to the intermediate waters, biogeochemical time-series observations at station KNOT, vertical fluxes in the water column, and the east–west Pacific Ocean comparison of ecosystems and biogeochemical regimes.
