Water-column Carbohydrate Percentages Measured during the JGOFS Equatorial Pacific Process Study

The Equatorial Pacific Process Study (EQPAC) was conducted along 140 deg W longitude during 1992. 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. Carbohydrate percentages (weight percent of total carbohydrates) were measured from floating sediment trap samples (carbFST) and from plankton tows (carbPT). The following carbohydrates were measured: lyxose, arabinose, rhamnose, ribose, xylose, fucose, mannose, galactose, glucose, and total carbohydrates normalized to organic carbon (mg/100mg of organic carbon). In addition, the following parameters were also measured: particulate organic carbon, particulate inorganic carbon, total particulate nitrogen, and total flux of particulate matter.
