SEFSC GoMMAPPS 2018 Winter Aerial Survey

Original provider: NOAA Southeast Fisheries Science Center (SEFSC) Dataset credits: NOAA Southeast Fisheries Science Center (SEFSC) Abstract: As part of GoMMAPPS, the Southeast Fisheries Science Center conducted aerial surveys of continental shelf waters (up to the 200-m isobath) in the U.S. Gulf of Mexico. The survey was conducted between 18 January and 14 March 2018 aboard a NOAA Twin Otter aircraft at an altitude of 600 feet (183 m) and a speed of 100-110 knots (185-204 kph). Survey tracklines were oriented perpendicular to the shoreline and latitudinally spaced 20 km apart. The survey was designed for analysis using Distance sampling with a two-team (independent observer) approach to correct for perception bias in resulting abundance estimates. The study area extended from the shoreline to the 200-m isobath between Tampa, FL and Port O’Connor, TX, and included fine-scale tracklines over estuarine waters of Mississippi Sound.原始提供方：美国国家海洋和大气管理局东南渔业科学中心（NOAA Southeast Fisheries Science Center, SEFSC） 数据集归属：美国国家海洋和大气管理局东南渔业科学中心（NOAA Southeast Fisheries Science Center, SEFSC） 摘要： 作为GoMMAPPS项目的组成部分，美国国家海洋和大气管理局东南渔业科学中心针对美国墨西哥湾的大陆架海域（最深至200米等深线）开展了航空勘测。本次勘测于2018年1月18日至3月14日期间实施，搭载NOAA双水獭（NOAA Twin Otter）型航空器，飞行高度为600英尺（183米），航速为100-110节（185-204公里/小时）。勘测航线垂直于海岸线布设，沿纬度方向间隔20千米。本次勘测采用双团队（独立观察员）的距离抽样法开展分析设计，以校正最终资源丰度估算中的感知偏差。 研究范围覆盖从佛罗里达州坦帕市（Tampa, FL）至德克萨斯州奥康纳港（Port O’Connor, TX）之间的海岸线至200米等深线海域，同时包含密西西比湾（Mississippi Sound）河口海域的精细尺度勘测航线。
