An Ellipsoidally Referenced Survey (ERS) using two Teledyne Reson SeaBat T50-P multibeam echosounders, in dual-head configuration, was conducted by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) covering the nearshore, seaward side of Rockaway Peninsula, New York (NY), from October 4-6, 2019. This dataset, Rockaway_2019_MBES_Leg1_xyz.zip, includes the processed elevation point data (x,y,z), as derived from a 1-meter (m) bathymetric grid from the first leg of the survey. Additionally, the dataset Rockaway_2019_MBES_Leg1_Backscatter.zip includes the acoustic backscatter intensity data in 32-bit floating point GeoTIFF (.tif) format. Survey efforts were cut short due to inclement weather and the survey was resumed later in the month (Leg 2). Both survey legs have been made available in this publication independently as there is evidence of morphologic change, and therefore the legs could not accurately be combined into a comprehensive product.
