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.
