SRA accession and collection metadata for sediments samples collected at two Chesapeake Bay stations from Mar 2017 to Aug 2018

To examine the seasonality of sulfur oxidizers in surface sediments in seasonality oxygen stressed sediments of the Chesapeake Bay, surface sediments (0-0.5 cm depth) were collected on 10 occasions spanning all seasons over the course of two years by gravity coring at a pair of stations with differing summer bottom water oxygen concentrations. Samples were collected from March of 2017 to August of 2018. One station was located in the central channel which experiences severe summer hypoxia (CB4.3C) and one station was located on an adjacent shoal where bottom waters are better ventilated (CB4.3W; station names associated with Chesapeake Bay Water Quality Monitoring Program). At both stations, the waters are mesohaline and the sediments are fine grained. The study was designed to enable a description of the seasonality of benthic microbial communities at paired locations with contrasting degrees of bioturbation.
