Summary |
Equatorial Pacific Carbon Cycle: A two-part special
issue (Volume 42, Issue 2-3 and Volume 43, Issue 4-6) has been prepared
summarizing the results from the JGOFS Process Study (EqPac)
in the central and eastern equatorial Pacific. Most of the papers are from
the US JGOFS study but the France and Australia JGOFS studies are also
represented. The purpose of this study was to determine the fluxes of carbon
and related elements, and processes controlling those fluxes, between the euphotic zone and the atmosphere and deep ocean. The US
JGOFS study was conducted in 1992 and consisted of survey and time series
cruises designed to observe a wide range of temporal and spatial scales. The
dominant oceanographic event during this period was the 1991-1992 El Niño. The equatorial Pacific plays an important role
in the global carbon cycle. Because of upwelling, the CO2 in the
surface water is high and this region is the ocean's largest source to the
atmosphere. It may also contribute a significant fraction of the ocean's new
production. The magnitude of these fluxes varies interannually
in association with the El Niño Southern
Oscillation (ENSO). At the same time, it is considered a
high nutrient-low chlorophyll (HNLC) regime, which means that the
fluxes are low for the nutrient levels present. The record of how these
fluxes changed in the past is preserved in the underlying sediments. |
