Deployment: TT013

1992-10-30 - 1992-12-13 U.S. JGOFS Equatorial Pacific Platform:R/V Thomas G. Thompson (vessel)

Description

Purpose: Benthic Survey, 12°N-12°S at 140°W

TT013 was one of five cruises conducted in 1992 in support of the U.S. Equatorial Pacific (EqPac) Process Study. The five EqPac cruises aboard R/V Thomas G. Thompson included two repeat meridional sections (12°N - 12°S), 2 equatorial surveys, and a benthic survey (all at 140° W). The scientific objectives of this study were to observe the processes in the Equatorial Pacific controlling the fluxes of carbon and related elements between the atmosphere, euphotic zone, and deep ocean. As luck would have it, the survey window coincided with an El Nino event. A bonus for the research team.
