"The edge of the continental shelf is a key location where nutrient-rich water upwells to the surface, stimulating the growth of the tiny plants and animals that form the basis of the food web," said Glen Gawarkiewicz, a physical oceanographer at Woods Hole Oceanographic Institution.
This water mass occurs at the thermocline depth in the open ocean, which intrudes over the inner continental shelf near the bottom, and eventually upwells to the surface near the coast (Moreira da Silva, 1971; Gonzalez-Rodriguez et al., 1992; Campos et al., 2000; Mahiques et al, 2005).
Due to natural upwells and ocean acidification, more corrosive water below 1,000 m depths (the saturation horizon) is reaching the upper 200 m--where the marine snails feed on phytoplankton and detritus.
The Southern Ocean is the only place on the globe where water upwells from this depth.
