Seasonal Succession of Bacterial Communities in Coastal Waters of the Western Antarctic Peninsula

Abstract: From winter to late summer during the 2013-2014 season at Palmer Station, Antarctica, we collected weekly to bi-weekly samples of the seawater intake to measure changes in bacterial community composition, based on sequencing 16S rRNA genes. Along with the sequences, we collected data on environmental parameters in the samples (chlorophyll a, bacterial production, salinity, nutrients, bacterial cell numbers, and particulate organic carbon and nitrogen).
