Abundance, Biovolume and Biomass of Heterotrophic Dinoflagellates Measured during the JGOFS Equatorial Pacific Process Study
Listed in NASA Earthdata CMR
The Equatorial Pacific Process Study (EQPAC) was conducted along 140 deg W longitude during 1992.
Description
Four cruises took place: February 3 - March 9, March 19 - April 15, August 5 - September 18, and September 24 - October 21. A fifth benthic cruise and sediment trap legs were added.
During the first cruise (TT007), 15 stations were occupied along 140 deg W longitude from 12 deg N latitude to 12 deg S latitude. During the second cruise (TT008), data were collected at 8 stations along 140 deg W longitude from 9 deg S latitude to 9 deg N latitude. During the third cruise (TT011), data were collected at 15 stations along 140 deg W from 12 deg N latitude to 12 deg S latitude.

During the fourth cruise (TT012), data were collected at 5 stations along 140 deg W longitude from 17 deg S latitude to the equator. Samples were collected at each station in a vertical profile using the CTD rosette bottle sampler for the measurement of heterotrophic dinoflagellates. Microzooplankton were enumerated by inverted microscopy of settled samples.
Abundance (cells/ml), biovolume (cubic micrometers), and biomass (ugC/l) were measured. The data is public domain and can be retrieved on-line at "usjgofs.whoi.edu/jg/dir/jgofs/" [The information in this summary was derived from the JGOFS World Wide Web pages.]
