These data map in high detail surficial cross-sections of North Core Banks, a barrier island in Cape Lookout National Seashore, NC, in October 2022. U.S. Geological Survey field efforts are part of an interagency agreement with the National Park Service to monitor the recovery of the island from Hurricanes Florence (2018) and Dorian (2019). Three sites of outwash, overwash, and pond formation were targeted for extensive vegetation ground-truthing, sediment samples, bathymetric mapping with a remote-controlled surface vehicle, and uncrewed aerial systems (UAS) flights to collect multispectral imagery. Five semi-permanent ground control points were also installed and surveyed to act as control for additional aerial...

The data details common loon locations based on archival geolocator tag information, characteristics of common loon dives during wintering, and common loon locations based on telemetry data. Satellite transmitters (Model PTT-100, Microwave Telemetry, Inc) were implanted in 31 adult male (marked during July 2010 and July 2011) and 27 juvenile (marked during August 2014 and August 2015) common loons that were captured on breeding lakes in Minnesota, Wisconsin, and the Upper Peninsula of Michigan. The satellite transmitters were programmed to transmit on a variable schedule based on the anticipated stage of migration during the loon’s annual cycle. We utilized the most accurate locations per 8-hour transmission period...

Various water column variables, including salinity, dissolved inorganic nutrients, dissolved inorganic carbon, and radio-carbon isotopes were measured in samples collected using a Niskin-bottle rosette at selected depths from deepwater sites offshore the US Mid- and South Atlantic from September 2017 to April 2019. CTD (Conductivity Temperature Depth) data were also collected at each depth that a Niskin-bottle sample was collected and are presented along with the water sample data during the following five cruises: PC1704 (USGS field activity 2017-004-FA) in September 2017, ENG615 (USGS field activity 2018-024-FA) in June 2018, AT41 (USGS field activity 2018-042-FA) in August 2018, BMCC-2018 (USGS field activity...
