Bathymetry and acoustic backscatter data collected in Long Island Sound for the Phase III Long Island Sound Seafloor Mapping Project 2015 (NCEI Accession 0167532)

This dataset contains multibeam bathymetry, uncertainty, and backscatter GeoTIFFs with 1x1 meter cell size represent water depth and acoustic intensity of the seafloor from the Phase III Long Island Sound Benthic Habitat Priority Areas of Interest in the Long Island Sound. These datasets were surveyed by NOAA Ship Nancy Foster R-352 in 2015 using 400 khz Reson 7125 multibeam sonars in coordination with the NOAA Biogeography Branch and the Integrated Ocean and Coastal Mapping Branch. The multibeam was corrected, calibrated, and integrated into a seamless 32-bit raster using CARIS and ArcGIS. Backscatter data was collected and mosaicked into a raster using Fledermaus Geocoder Toolbox, ArcGIS 10.4, and PCI Geomatica 2016 software at the Biogeography Branch by NOAA contractors.

本数据集收录了多波束测深、不确定性和后向散射GeoTIFF图像，其1x1米格网尺寸用以表示长岛海峡第三阶段优先调查区域的底质水深度和声学强度。这些数据集由2015年美国国家海洋和大气管理局（NOAA）的Nancy Foster号R-352船队进行测绘，并采用400 kHz的Reson 7125多波束声纳，在NOAA生物地理学分支和综合海洋与海岸测绘分支的协同下完成。多波束数据经过校正、校准并整合为无缝32位栅格，使用了CARIS和ArcGIS软件。后向散射数据由NOAA承包商在生物地理学分支通过Fledermaus Geocoder Toolbox、ArcGIS 10.4及PCI Geomatica 2016软件进行采集和镶嵌。
