Bacteria-algae associations in the sea ice and upper water column of the Ross Sea in late austral summer
Publshed by the National Science Foundation, Office of Polar Programs. The ecological role of heterotrophic bacteria in the microbial food web of the Southern Ocean is unresolved. A coupling between phytoplankton and bacterial production is well documented in mid-to low-latitude oceans (e.g., Bird a...

A coupling between phytoplankton and bacterial production is well documented in mid-to low-latitude oceans (e.g., Bird and Kalff 1984; Cole, Findlay and Pace1988) and is thought to result from the heterotrophic uptake of dissolved organic carbon (DOC) released by the primary producers (i.e. the "microbial loop;" Pomeroy 1974; Bjørnsen 1988).
