CHLOROPHYLL A profile data collected in the North Atlantic Ocean on the ALBATROSS IV, ENDEAVOR and OCEANUS cruises AL9505, AL9506 and others as part of the GB project from 1995-02-11 to 1996-06-12 (NODC Accession 0101503)

NODC Accession 0101503 includes profile, discretely sampled and biological data collected aboard the ALBATROSS IV, ENDEAVOR and OCEANUS during cruises AL9505, AL9506, AL9508, AL9605, AL9607, EN261, EN263, EN265, EN276, EN278, EN282 and OC275 in the North Atlantic Ocean from 1995-02-11 to 1996-06-12. These data include CHLOROPHYLL A. The instruments used to collect these data include bottle. These data were collected by David Mountain and Maureen Taylor of National Marine Fisheries Service as part of GB. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NODC on 2013-01-18. The following is the text of the abstract provided by BCO-DMO: Raw Extracted Chlorophyll Data from Broadscale CTD stations, 1995 and 1996. PI NOTES: The 1995 and 1996 bottle data were collected with a GO rosette mounted above the MK5 CTD. Water for chlorophyll extractions was taken at priority 1 and 2 stations and at 3 "standard" depths (according to a protocal set up by Ted Durbin and Dian Gifford at the University of Rhode Island). For each bottle, 3 replicate samples were run for consistency. 50 mls were filtered for 3 size fractions: total chlorophyll, chlorophyll from water filtered through a <20 micron mesh and chlorophyll from water filtered through a <5 micron mesh. This means that for any one station, there were 27 test tubes: 3 depths, 3 replicates, 3 size fractions. The samples were usually read at sea (after the 24 hour acetone extraction). If not, Ted Durbin"s Lab read them when the ship returned. The companion object for this data is chloro_bot_chem, which details salinity, temperature, fluorometry and tranmissometry collected from the same bottles.
