Summary
Abstract: 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 (November 1 - December 7) 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. During the fifth
benthic cruise (TT013), data were collected at 16 stations along 140
deg W from 12 deg S latitude to 9 deg N latitude.

CTD casts at each station provided the following information:
sample depth, depth reported as pressure, temperature, conductivity,
salinity, potential temperature, potential density, sigma-t,
fluorescence, particle beam attenuation, and photosynthetically
available radiation (PAR). The depth of the ocean mixed layer was
also reported. The mixed layer is defined as a density increase of
0.03 density units from the first surface value.

The data is public domain and can be retrieved on-line at
