Navigation data (ASCII CSV format) for R/V Lowell Weicker surveys, western Long Island Sound (2023)

These data files provide the survey boat navigation data during a four-day survey using the Ponar Imaging and Sampling System for Assessing Habitat (PISSAH) deployed from the Research Vessel Weicker conducted from June 12-16, 2023. The PISSAH system was used to acquire both physical sediment grab samples as well as the GoPro video from 60 sites in the Phase III area of the Long Island Sound Cable Fund (LISCF) Seafloor Habitat Mapping Initiative. These sites were identified in the Phase IIIA area based upon an analysis of existing acoustic backscatter data obtained from multiple surveys by NOAA that exhibited what appeared to be inconsistent gray scale settings. The navigation files are in ASCII comma-separated format with column headers. Funding was provided by the Long Island Sound Cable Fund Seafloor Habitat Mapping Initiative administered cooperatively by the EPA Long Island Sound Study and the Connecticut Department of Energy and Environmental Protection (DEEP).

本数据集包含2023年6月12日至16日期间，搭载于韦克号研究船（Research Vessel Weicker）的生境评估波纳尔成像与采样系统（Ponar Imaging and Sampling System for Assessing Habitat，PISSAH）开展的为期四天海底调查所获取的调查船导航数据。该系统被用于采集长岛海峡电缆基金海底生境制图计划（Long Island Sound Cable Fund Seafloor Habitat Mapping Initiative，LISCF）第三阶段区域内60个点位的实物沉积物抓样与GoPro视频影像。上述点位是基于美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration，NOAA）多次调查获取的现有声学背散射数据分析结果，在第三阶段A区内选定的，该批声学数据存在疑似不一致的灰度设置问题。本导航数据文件采用ASCII逗号分隔格式，并附带列标题。本项目资助由长岛海峡电缆基金海底生境制图计划提供，该计划由美国环境保护署（Environmental Protection Agency，EPA）长岛海峡研究项目与康涅狄格州能源与环境保护部（Connecticut Department of Energy and Environmental Protection，DEEP）联合管理。
