Original provider: NOAA Southwest Fisheries Science Center (SWFSC) Dataset credits: Marine Mammal and Turtle Division, Southwest Fisheries Science Center, NMFS, NOAA Abstract: This 1999 eastern tropical Pacific cetacean line-transect survey was part of the Stenella Abundance Research Project (STAR), a multi-year cetacean and ecosystem assessment study designed to assess the status of dolphin stocks which have been taken as incidental catch by the yellowfin tuna purse-seine fishery in the Eastern Tropical Pacific. This survey was conducted by the NOAA Southwest Fisheries Science Center aboard NOAA ships <i>David Starr Jordan</i> and <i>McArthur</i> for a combined total of approximately 31,000 kilometers surveyed from late July to early December 1999. This dataset provides the time-date and geographical coordinates, by species/stock, of all cetaceans detected during the survey, as well as the daily and intra-daily start and end points of the line-transect survey by the NOAA Ship <i>David Starr Jordan<i>.原始提供方：美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）西南渔业科学中心（Southwest Fisheries Science Center, SWFSC） 数据集贡献方：美国国家海洋渔业局（National Marine Fisheries Service, NMFS）下属美国国家海洋和大气管理局西南渔业科学中心海洋哺乳动物与海龟分部 摘要：本次1999年东热带太平洋鲸类线样调查，系长吻海豚丰度研究项目（Stenella Abundance Research Project, STAR）的组成部分。该项目为一项跨年度鲸类与生态系统评估研究，旨在评估东热带太平洋黄鳍金枪鱼围网渔业兼捕所涉及的海豚种群现状。本次调查由美国国家海洋和大气管理局西南渔业科学中心组织实施，搭载"戴维·斯塔尔·乔丹"号（David Starr Jordan）与"麦克阿瑟"号（McArthur）两艘美国国家海洋和大气管理局科考船，于1999年7月下旬至12月初完成总调查航程约31000公里。本数据集记录了本次调查中观测到的所有鲸类的时间戳与地理坐标，并按物种/种群进行分类；同时还包含"戴维·斯塔尔·乔丹"号执行的线样调查的每日及日内航线起止坐标点。
