Bathymetric data from the project was collected with multibeam echosounder (MBES) and will be utilized by the Office of Coast Survey (OCS) to update the nautical charts in the surveyed area. Field provided bathymetry and backscatter products.This report does include data acquisition and processing information.The vertical datum for this project is MLLW 83-01 NTDE. Tidal data was applied with a finalized TCARI grid (NF1601.tc) supplied by CO-OPS with verified tides values obtained from the assigned NWLON tide gauges. There were no DTONs created for this survey.NOAA Ship Nancy Fosterhttps://www.ngdc.noaa.gov/ships/nancy_foster/M1907_NF_10_mb.htmlThis survey will be used to update NOAA navigational products. This survey does meet charting specifications and is adequate to supersede prior data.M-I907-NF-16H12936Puerto RicoCaribbean Sea10 NM North of Isla de Culebra40000Reson7125-SV2Multibeam Echo SounderKongsbergEM710Multibeam Echo SounderNorth American Datum of 1983 (NAD83)Mean Lower Low WaterTCARIUTM Zone 20NNOAA Ship NANCY FOSTER2016-04-192016-04-26Timothy Battista2017-11-28
