Original provider: NOAA Southwest Fisheries Science Center (SWFSC) Dataset credits: Marine Mammal and Turtle Division, Southwest Fisheries Science Center, NMFS, NOAA Abstract: This 1998 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>, <i>Endeavor</i> and <i>McArthur</i> for a combined total of approximately 42,000 kilometers surveyed from late July to early December 1998. 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>McArthur</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） 数据集致谢： 美国国家海洋和大气管理局（NOAA）国家海洋渔业局（National Marine Fisheries Service, NMFS）西南渔业科学中心海洋哺乳动物与海龟分部 摘要： 本次1998年东热带太平洋鲸类线样调查属于细吻海豚种群丰度研究项目（Stenella Abundance Research Project, STAR）的组成部分，该项目为多年期鲸类与生态系统评估研究，旨在评估东热带太平洋海域被黄鳍金枪鱼围网渔业兼捕的海豚种群现状。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，搭载于NOAA旗下戴维·斯塔尔·乔丹号（David Starr Jordan）、奋进号（Endeavor）与麦克阿瑟号（McArthur）科考船，于1998年7月下旬至12月初累计完成调查航程约42000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-日期信息与地理坐标（按物种/种群分类），同时包含NOAA科考船麦克阿瑟号所执行的线样调查的每日及日内起止点位数据。
