Abstract:

This dataset includes October 2016 field measurements that complement marsh sediment and water samples collected for characterization of microbial communities in Louisiana marshes, a component of a longitudinal study. Water samples collected offshore from the marsh vegetation edge and sediment samples collected both inland and offshore from the marsh vegetation edge are supported by meter data (water pH, temperature, salinity, and dissolved oxygen; soil salinity, pH, and temperature), as well as other field observations. Complementary bacterial community composition datasets from October 2016 marsh sediment and water samples will be reported separately. Site names are as follows: TB-01: 29.29304, -90.60472 TB-02: 29.29146, -90.60282 TB-05: 29.30222, -90.59861 TB-06: 29.31, -90.59944 GI-01: 29.30288, -89.97092 GI-02: 29.27653, -89.97535 GI-03: 29.28895, -90.04267 GI-04: 29.26583, -90.02487 GI-05: 29.2801, -89.97583 PS-03A: 29.46098, -89.87503 PS-05: 29.45081, -89.75 PS-06: 29.44583, -89.87615 PS-07: 29.4742, -89.85646
