2017-2018 USAP Field Season
Antarctic microbial networks and DMSP: Linking diversity, biogeochemistry, and functional gene expression
Dr. Peter Dylan Countway
Bigelow Laboratory for Ocean Sciences
Supporting Stations: Palmer Station
The objective of this project is to link the molecular microbial ecology of the Western Antarctic Peninsula and/or Ross Sea to the regionally-relevant (and crucial) biogenic dimethylsulfoniopropionate (DMSP) cycle that may influence the biological structure and function of this sensitive marine ecosystem.
Field Season Overview
Researchers will deploy to Palmer Station to conduct incubation experiments using water collected from Stations B and E. They will use Zodiacs and rigid-hulled inflatable boats to access their research areas and will use the Seabird ECO rosette to collect water samples. The team will perform on-station incubations in their own Ecostat incubator. Lab-based activities will include water filtration for various types of samples, sample processing for measurement on gas chromatograph equipment, chlorophyll and bacterial productivity measurements, and preservation of samples for flow-cytometry and microscopy. At the end of the season, samples will be shipped to the home institution for further analyses.
