- Diversity and function of organic matter and biological communities across the ocean depths and over a wide latitude
- Interactions between surface- and deep-ocean processes
- Movement of water and organic material from land to the ocean and among large oceanic water masses
Along the nearly 5,000-mile transect aboard R/V Knorr from Montevideo, Uruguay, to Bridgetown, Barbados, the cruise will cross and sample the plume of the Amazon River and three large oceanic water masses: the North Atlantic Deep Water, Antarctic Bottom Water, and Antarctic Intermediate Water. Ultimately, the team hopes to assemble an integrated, biochemical picture of how carbon cycles from the surface to depths (and throughout the depths). The information they provide will help form the foundation for future predictive capabilities of processes that are important to life in the ocean, to the planetary climate system, and to the cycling of carbon and nutrients from land and within the ocean.
