Processed bathymetry data (GSF format) from central Long Island Sound, survey LIS4-West-C, LIS Phase IV seafloor mapping, R/V Seawolf, September 2022

This is processed multibeam data in GSF format collected in support of the Long Island Sound Cable Fund Seafloor Habitat Mapping Initiative, Phase IV. The survey area is located south of New Haven, CT. This is the processed data from one of the three surveys from which the Backscatter and Bathymetry grids in the LIS4A:SBU_Acoustics data collection were generated. This processed multibeam data is for the survey LIS4-West-C collected using a Kongsberg EM2040P MKII swath mapping echo-sounder system on R/V Seawolf in September, 2022. The GSF data format is compatible with MB-System format 121. Vessel navigation is referenced to WGS84. Not to be used for Navigation.

本数据集为采用GSF格式（GSF）存储的经处理多波束数据（multibeam data），采集工作旨在支撑**长岛海峡电缆基金海底栖息地测绘计划第四阶段**。调查区域位于康涅狄格州（CT）纽黑文以南。本数据集是三项勘测数据的处理成果之一，LIS4A:SBU_Acoustics数据集的反向散射（Backscatter）与水深地形（Bathymetry）格网数据即由这三项勘测生成。
本次处理的多波束数据对应勘测任务LIS4-West-C，于2022年9月搭载于"海狼号"研究船（R/V Seawolf），使用康斯伯格Kongsberg EM2040P MKII条带测绘测深仪（swath mapping echo-sounder）完成采集。
GSF格式兼容MB-System格式121（MB-System）。船舶导航采用WGS84坐标系（WGS84），本数据不得用于导航用途。
