Surface phytoplankton chlorophyll distribution continuously observed in the JARE-26 cruise (1984/85) to Syowa Station, Antarctica (SIBEX II)
A continuous measuring-recording system of surface chlorophyll α, which is equipped with a personal computer, was used in the 26th Japanese Antarctic Research Expedition (JARE-26) cruise of icebreaker SHIRASE to Syowa Station, Antarctica, in 1984-1985 as part of the Second International BIOMASS prog...
