These waters contain nutrients from the sunken carcasses of small organisms. This surfacing thus brings nutrients to the surface, nourishing plankton, and is an important aspect of the marine food web.

In dry seasons, the water table may drop several feet in some areas before rising again during the next wet season.
The majority are small crustaceans (copepods, krill), arrowworms, and gelatinous creatures that feed primarily on phytoplankton.
