The Joint Global Ocean Flux Study (Canada) in the NE subarctic Pacific

This volume of DSR II is dedicated to the Canadian Joint Global Ocean Flux Study (JGOFS) in the NE subarctic Pacific. This oceanic province is one of three High Nitrate Low Chlorophyll (HNLC) regions in the world oceans. Furthermore, this region is characterised by a shallow (ca. 100-120 m) permanent pycnocline during winter, which permits relatively high numbers of phytoplankton and micro-grazers to subsist over winter, which in turn strongly influences pelagic community structure. The 5-year field study encompassed two phases - phase 1 (seven voyages between September 1992 and May 1995), and the intensive phase 2 (six voyages between September 1995 and June 1997). Each voyage transected line P - from the coastal ocean westward to the open ocean. In addition to the JGOFS study, this volume also includes analyses of long time-series (> 20 yr) data sets from Ocean Station Papa (OSP; 50 degrees N 145 degrees W) and other stations in the coastal and open ocean.
