| Dataset-specific Instrument Name | Eppley Longwave Radiometer |
| Generic Instrument Name | Eppley Longwave Radiometer |
| Generic Instrument Description | The Eppley Precision Infrared Radiometer (PIR) pyrgeometer measures longwave (infrared) radiation. It is housed in a weatherproof titanium canister that has been painted with a very flat black paint that absorbs radiation. A small glass dome at the top of the instrument is covered with an 'interference coating' which allows only infrared radiation to come through. Light levels are detected as temperature changes creating voltages in fine wire coil detectors. more from Eppley Labs |
| Dataset-specific Instrument Name | Improved Meteorological Recorder |
| Generic Instrument Name | Improved Meteorological Recorder |
| Generic Instrument Description | An IMET Recorder is an instrument package that can be mounted on a ship or buoy to record mean weather data including air and sea-surface temperature, incoming short and long-wave radiation, precipitation, humidity, wind velocity and barometric pressure. Each sensor in the system communicates digitally and returns calibrated values to a central data recorder. |
| Dataset-specific Instrument Name | Vector-Averaging Wind Recorder |
| Generic Instrument Name | Vector-Averaging Wind Recorder |
| Generic Instrument Description | The Vector-Averaging Wind Recorder (VAWR) is a system designed by researchers at Woods Hole Oceanographic Institution (WHOI) to make surface meteorological measurements. The standard WHOI Vector Averaging Wind Recorder (VAWR) of the late 1980s through early 1990s was mounted on a toroid buoy (Dean and Beardsley, 1988). In addition to wind speed and direction, the VAWR could also be configured to record water temperature and conductivity data from sensors mounted at 1 meter depth on the mooring bridle of the buoy (Trask et al., 1995).

| Description | Woods Hole Surface Mooring Deployment 2
A surface mooring was deployed off the coast of Oman along the climatological axis of the Findlater Jet from October 1994 to October 1995.
The location chosen for the surface mooring, 15.5°N, 61.5°E, was close to the climatological maximum in the wind speed during the height of the Southwest Monsoon. Two separate mooring deployments, the first beginning October 15, 1994, and ending April 20, 1995, and the second starting April 22, 1995, and ending October 10, 1995, were used so that a second set of freshly calibrated sensors was deployed prior to the onset of the Southwest Monsoon.

| Description | Mooring Recovery and Redeployment Cruise |
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.
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).
