Joint Global Ocean Flux (JGOFS
) program studies of the North Atlantic spring plankton bloom, upwelling in the equatorial Pacific Ocean, the monsoon system in the Arabian Sea of the Indian Ocean, and the processes of the southern ocean around Antarctica provide direct observations of the sensitivity of foraminifers to sea surface temperature (and other environmental conditions).

The field study for this research program, a combined effort of the Joint Global Ocean Flux Study (JGOFS
) program and the US Office of Naval Research, began in late 1994 and continued for about one year.
In addition, they were too noisy for acoustic operations, an essential element of oceanographic research, and too small and lacked the seakeeping qualities to accommodate large science parties for long periods to carry out the global scale programs then being contemplated, especially the World Ocean Circulation Experiment (WOCE) and the Joint Global Ocean Flux Study (JGOFS
These range from regional coastal studies (Nixon, 1996) and expeditions to specific sites (e.g., the Black Sea, Sargasso Sea, Cariaco Trench), to longer-term environmental studies (Feller and Karl, 1996), and ambitious global programs like JGOFS (Joint Global Ocean Flux Studies) aimed at understanding the workings of the global climate system.
When agencies earmark research funds for large programs like GLOBAL CHANGE, GLOBEC, JGOFS, RIDGE, BIODIVERSITY, etc., the pool of funds remaining for support of innovative, individual investigator-initiated work in other areas is generally reduced (i.e., program-specific augmentations rarely surviving intact for multiple years).
In recent years, large international programs including the World Ocean Circulation Experiment (WOCE) and the Joint Global Ocean Flux Study (JGOFS) have provided scientific justification for continuation and expansion of the multidisciplinary Bermuda measurements.
For this reason it is essential that the observations continue beyond the lives of some of the large field programs like WOCE and JGOFS, which will end in a few years.
