Duplicate Stream Sample Analyses by Laboratories of the U.S. Geological Survey New York Water Science Center and Adirondack Lake Survey Corporation Applied to Adirondack Stream Monitoring Data, 2003-2017 Duplicate Stream Sample Analyses by Laboratories of the U.S. Geological Survey New York Water Science Center and Adirondack Lake Survey Corporation Applied to Adirondack Stream Monitoring Data, 2003-2017

This dataset contains a comparison of chemical analysis results obtained by the U.S. Geological Survey (USGS) New York Water Science Center Soil and Low-Ionic Strength Water Quality Laboratory and the Adirondack Lake Survey Corporation (ALSC) Laboratory. Duplicate samples were collected biweekly from Buck Creek and the North and South Tributaries of Buck Creek from September 5, 2006...

Radiochemical Data From Sediment Cores Collected on Deer Island, Mississippi Radiochemical Data From Sediment Cores Collected on Deer Island, Mississippi

In December 2021, four sediment push cores (core names appended with 'M' for marsh push core) and peat augers (core names appended with 'R' for Russian peat auger) were collected from the marshes of Deer Island, Mississippi during U.S. Geological Survey (USGS) field activity number (FAN) 2021-351-FA. Select intervals from the manual push cores were analyzed for determination of lead-210...

Seagrass map, Cat Island and Ship Island, Mississippi, 2014 Seagrass map, Cat Island and Ship Island, Mississippi, 2014

This product depicts the spatial coverage of seagrass beds from 0.5-m color-infrared orthoimagery for Cat Island and Ship Island, Mississippi from early fall of 2014. Specifically, the map includes presence and absence of seagrass beds within a potential seagrass extent that was based on topobathymetric data. A minimum mapping unit of 4 square meters was used for this mapping effort.
