Primary production, defined as fixation of [ 14 C]bicarbonate, occurs in the waters under the Ross Ice Shelf, Antarctica. About 1.5 g C·m −2 is fixed annually. This amount is sufficient to support the observed macrofaunal population and may be due to the activity of chemoautotrophic nitrifying bacteria.
