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>Endeavor<i>.

Purpose:
The primary purpose of the survey was to collect information necessary to estimate abundance of dolphin stocks in the eastern tropical Pacific that are taken as bycatch in the yellowfin tuna purse seine fishery.

摘要：
本项1998年东太平洋热带鲸类线形断面调查为“斯特林纳丰度研究项目”（STAR）的一部分，该研究项目是一项跨年度的鲸类及生态系统评估研究，旨在评估那些在东太平洋金枪鱼围网渔业的附带捕获中被视为捕捞对象的鲸鱼种群的状态。该调查由NOAA西南渔业科学中心在NOAA船只《大卫·斯塔·乔丹号》、《奋进号》和《麦克阿瑟号》上执行，总计约42,000公里的调查范围，时间从1998年7月下旬至12月初。本数据集提供了在调查期间检测到的所有鲸类的时-日期和地理坐标，以及由《奋进号》执行的线形断面调查的每日及日内起止点。

目的：
调查的主要目的是收集必要信息，以估算在东太平洋黄鳍金枪鱼围网渔业的附带捕获中被捕捞的鲸鱼种群的丰度。
