Parameters

ParameterDescriptionUnits
yearyear cruise took place.
eventA unique number assigned to each over the side sampling activity. This number is a composite of date and time UTC(GMT) in the form MMDDHHmm that indicates the starting time of the sampling activity. Generally, one event began as the preceding event ended.
staStation. A unique number designating a general geographic location at which a suite of sampling activities may occur; occupied sequentially during the cruise
cast_typea sampling activity identifier, where: CTD = CTD rosette bottle cast TM = trace metal free rosette bottle cast
latstarting latitude for each event (negative = south) decimal degrees
lonstarting longitude for each event (negative = west) decimal degrees
activity_and_commentsIdentifies the sampling method, generally followed by a sampling sequence number for
seqis a sequential (within each station) entry in the bridge log of all over the side activities for which gear was deployed.
personName of the scientist(s) involved in the particular sampling event or responsible for the resulting data.
castCTD or TM cast number within a station location (forms unique profile identifier when combined with station number) dimensionless

Project Information

U.S. JGOFS Arabian Sea (Arabian Sea)


Coverage: Arabian Sea


The U.S. Arabian Sea Expedition which began in September 1994 and ended in January 1996, had three major components: a U.S. JGOFS Process Study, supported by the National Science Foundation (NSF); Forced Upper Ocean Dynamics, an Office of Naval Research (ONR) initiative; and shipboard and aircraft measurements supported by the National Aeronautics and Space Administration (NASA). The Expedition consisted of 17 cruises aboard the R/V Thomas Thompson, year-long moored deployments of five instrumented surface buoys and five sediment-trap arrays, aircraft overflights and satellite observations. Of the seventeen ship cruises, six were allocated to repeat process survey cruises, four to SeaSoar mapping cruises, six to mooring and benthic work, and a single calibration cruise which was essentially conducted in transit to the Arabian Sea.

Program Information

U.S. Joint Global Ocean Flux Study (U.S. JGOFS)


Coverage: Global


The United States Joint Global Ocean Flux Study was a national component of international JGOFS and an integral part of global climate change research.

The U.S. launched the Joint Global Ocean Flux Study (JGOFS) in the late 1980s to study the ocean carbon cycle. An ambitious goal was set to understand the controls on the concentrations and fluxes of carbon and associated nutrients in the ocean. A new field of ocean biogeochemistry emerged with an emphasis on quality measurements of carbon system parameters and interdisciplinary field studies of the biological, chemical and physical process which control the ocean carbon cycle. As we studied ocean biogeochemistry, we learned that our simple views of carbon uptake and transport were severely limited, and a new "wave" of ocean science was born. U.S. JGOFS has been supported primarily by the U.S. National Science Foundation in collaboration with the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, the Department of Energy and the Office of Naval Research. U.S. JGOFS, ended in 2005 with the conclusion of the Synthesis and Modeling Project (SMP).
