Abstract:
This 1991 line-transect survey was designed to make abundance estimates for the cetacean species commonly found in California waters and killed in commercial gill net fishing operations. This survey was conducted by the NOAA Southwest Fisheries Science Center aboard NOAA Ship <i>McArthur</i> for a total of approximately 10,000 kilometers surveyed from late July to early November 1991. 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.

摘要：
本数据集源自1991年的线样调查（line-transect survey），旨在对加利福尼亚海域常见鲸类的种群丰度进行估算，该类鲸类曾在商业刺网捕捞作业中被误捕致死。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依托“麦克阿瑟”号（McArthur）科考船开展，于1991年7月下旬至11月上旬完成，总调查航程约10000公里。本数据集收录了本次调查期间探测到的所有鲸类按物种/种群分类的时间-日期信息与地理坐标，同时包含该线样调查的每日及日内作业起止点位。
