In accordance with SO #3423 - The Gulf of America and SO #3424 - Mount McKinley and Landmarks Honoring the Alaskan People, new USGS data releases specific to those named places will utilize the new name Gulf of America and the restored name Mount McKinley. Per USGS practice, historical data will retain the name of the geographic features as they were known at the time the data were originally released.

Hydrological Data Concerning Submarine Groundwater Discharge Along the Western Margin of Indian River Lagoon, East-Central Florida - December 2016 and January 2017

Summary
Indian River Lagoon, one of the most biologically diverse estuarine systems in the continental United States, is a shallow brackish lagoon stretching along approximately 200 kilometers (km) of the Atlantic coast of central Florida. Lagoon width varies from ~0.5 – 9.0 km, with substantial human infrastructure lining both shores.
Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) and USGS Caribbean-Florida Water Science Center (CFWSC) in Davies, working in collaboration with the St. Johns River Water Management District (SJRWMD) investigated submarine groundwater discharge at Eau Gallie North, a site along the western shore in the central section of the lagoon, using continuous resistivity profiling (CRP). The CRP array was towed behind a boat along five shore-parallel transects located ~125, 200, 350, 500 and 750 meters offshore and traversing ~1.5 km along north-south transects. Each transect was given a track name (EB., EC., ED., EE., and EF.) and lines were run both north to south and south to north. Repetitive profiles will be collected along these same tracks, at various times, in order to determine temporal variability. As resistivity is a function of both geology and salinity, temporal changes will reflect salinity changes, as the underlying geology will be presumed to remain constant. Resistivity data were assigned geographic coordinates and water depth values, in order to produce modeled resistivity, accounting for salinity and geologic parameters. This data release provides the raw resistivity, geographical, and water parameter data collected in December 2016 and January 2017.

Figure 1. Study site location. CRP data was collected on five shore-parallel lines (EB.-EF.) near Eau Gallie North (box, right), located in the central section of the Indian River Lagoon (red box, middle), on the Atlantic Coast of Florida (red box, left). Lines EA. and EG. were not run during these two trips due to water conditions. Line numbers and track names are correlated in a readme file included in all the zip files.
