Gut Content Analyis of Zooplankton in the Indian Ocean, 2014-2015We studied the gut contents of four dominant copepod species (Calanoides acutus, Calanus propinquus, Calanus simillimus and Rhincalanus gigas) during the summer (2014-2015) along a latitudinal gradient (sampled every 5° between 40°S and 65°S) in the Indian sector of the SO. Diatoms were the most abundant food item found in the guts, comprising 24 of the 25 species found, and 15 were common to the

Cold adaptation and functionality of the Antarctic Coastal Benthic ZonesAntarctic sediments and sea-ice are important regulators in global biogeochemical and atmospheric cycles. These ecosystems contain a diverse range of bacteria whose biogeochemical roles remains largely unknown and which inhabit what are continually low temperature habitats. An integrated molecular and chemical approach will be used to investigate the coupling of microbial biogeochemical processes

Microplankton, Nanoplankton and Picoplankton Measurements from the U.S. JGOFS Arabian Sea Process StudyA component of U.S. Joint Global Ocean Flux Study (JGOFS) is the Arabian Sea Process Study. Eleven cruises took place aboard the R/V Thomas G. Thompson for about sixteen months from October 1994 until January 1996. These cruises provided seasonal coverage of the annual monsoon and inter-monsoon cycles in the area southeast of Oman - from where the cruises were staged. The monsoons of the Arabian S

The role of grazing on sea ice algae and sea ice bacteria by ciliates and flagellated (zooplankton) in Terra Nova BaySea water was collected from a depth of 2 meters below the sea ice in the region of Gondwana Station in Terra Nova Bay. Initial measurements of chlorophyll along with presence and abundance of ciliates and flagellates were made. The collected water was then divided into a range of dilutions (with the addition of filtered sea water) and deployed under the ice for 24 hours. Subsequent chlorophyll a
