The U.S. EqPac process study consisted of repeat meridional sections (12°N
-12°S) across the equator in the central and eastern equatorial Pacific
from 95°W to 170°W during 1992. The major scientific program was focused
at 140° W consisting of two meridional surveys, two equatorial surveys,
and a benthic survey aboard the R/V Thomas Thompson. Long-term deployments
of current meter and sediment trap arrays augmented the survey cruises.
NOAA conducted boreal spring and fall sections east and west of 140°W from
the R/V Baldridge and R/V Discoverer. Meteorological and sea surface observations
were obtained from NOAA's in place TOGA-TAO buoy network.
The scientific objectives of this study were to determine the fluxes of
carbon and related elements, and the processes controlling these fluxes
between the Equatorial Pacific euphotic zone and the atmosphere and deep
ocean. A broad overview of the program at the 140°W site is given by
Murray et al. (Oceanography, 5: 134-142, 1992). A full description of the
Equatorial Pacific Process Study, including the international context and
the scientific results, appears in a series of Deep-Sea Research Part II
