Palmer Station Long-Term Ecological Research (LTER) R/V Polar Duke Marine Carbon Cycling Cruise Data, November 1992

Several independent, but complementary research objectives addressed various aspects of the marine carbon cycle including experimental studies of microbial loop processes. Studies ranged in scope from the deployment of an array of bottom-moored sediment traps, to in situ photographic measurements of particulate matter, to measurements of the response of bacterioplankton to increases in temperature and additions in organic substrates.

Research efforts also focused on autotrophic rate processes, krill biology, benthic protozoa and sulfur cycling.
