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.

Summary
In 2010, a video camera was installed near the northern boundary of the National Aeronautics and Space Administration-Kennedy Space Center (NASA-KSC) property along the Atlantic coast of Florida. A region extending 1 kilometer (km) to the south of the camera was established as the region of interest for the video image observations. During every daylight hour of camera operation from August 8, 2011 to July 24, 2012, a time exposure (timex) image product was created by averaging pixel color intensity for all frames collected during a 10-minute video at 2 frames per second (hertz, Hz). One timex image per day was used for analysis. The timex selected for each day was the product that was created when the tide level was closest to the Mean High Water (MHW) at the study site. Based on observed water levels from a nearby National Oceanic and Atmospheric Administration (NOAA) station, the MHW was determined to be 0.23 meters (m). The shoreline was manually identified as the wet-dry line within the region of interest of each available timex product. However, timex products were not available for about half of this timeframe due to camera malfunctions, adverse weather conditions (for example, fog), and/or a lack of daylight during the timing of MHW. Please carefully review the metadata for more information. This dataset is referenced in an associated publication that analyzed shoreline variability over daily to decadal timescales at NASA-KSC to quantify and compare variability and associated drivers at each timescale. For more information, refer to Conlin and others (2019).
