Upper ocean biogeochemistry
The sea surface and sunlit waters just below invite studies of plankton and the biogeochemistry of a changing ocean.
Midwater research
An area without sunlight or solid surfaces and often low levels of oxygen, the midwater of the ocean is the largest habitat on earth.
Seafloor processes
Bubbling gases, volcanic eruptions, landslides, and changing biological communities are among the complex processes of the deep seafloor.
