In situ net primary productivity and photosynthesis of Antarctic sea ice algal, phytoplankton and benthic algal communities
Primary production at Antarctic coastal sites is contributed from sea ice algae, phytoplankton and benthic algae. Oxygen microelectrodes were used to estimate sea ice and benthic primary production at several sites around Casey, a coastal area in eastern Antarctica. Maximum oxygen export from sea ic...
