Marine animal sighting and census data from NOAA Ship SURVEYOR as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 17 May 1975 to 13 October 1977 (NODC Accession 8000349)

Marine animal sighting and census data were collected from the NOAA Ship SURVEYOR from 17 May 1975 to 13 October 1977. Data were collected by the U.S. National Marine Fisheries Service (NMFS) as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F127 Marine Animal and Census format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f127.html. An analog file for this accession is available from NODC user services. The F127 format is used for data from field observations of marine animals. Data may be reported either for individual, random sightings or for sightings made as part of systematic ship or aircraft surveys along specified tracks. These data provide information on animal population densities and distributions, activities, migratory routes and breeding locales. Cruise or survey information, start and end positions, start and end times, and platform speed, direction, and altitude are reported for each observation or series of observations. Position, date and time are reported for each sighting location, along with a code indicating presence or absence of animals and, if present, their distance to the observer, shoreline, and ice edge and heading direction. For each sighting location, animal sighting data are reported by species for all observed species. Species identification, total number of individuals, and counts by age group (adults, subadults, juveniles, unknown) may be reported in summary for all animals sighted or by subgroups distinguished by sex, behavior, markings, or other characteristics. A text record is available for comments.本数据集收录了1975年5月17日至1977年10月13日期间，由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）“探索者号”（SURVEYOR）科考船收集的海洋动物目击与普查数据。该数据由美国国家海洋渔业局（U.S. National Marine Fisheries Service, NMFS）作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的一部分采集完成，后由美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照NODC标准F127海洋动物与普查格式完成标准化处理。完整格式说明可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/f127.html获取，本数据集的模拟文件可通过NODC用户服务渠道获取。 F127格式用于收录海洋动物野外观测数据，支持两类数据上报场景：针对单个随机目击事件的记录，以及沿指定航线开展的系统性船舶或航空调查中的目击记录。此类数据可提供海洋动物种群密度与分布、活动行为、洄游路径以及繁殖栖息地等核心信息。每份观测或观测序列均需记录巡航/调查信息、起止位置、起止时间，以及观测平台的航速、航向与飞行高度。每个目击位置需上报观测位置坐标、观测日期与时间，同时附带代码以标记该位置是否存在海洋动物；若存在动物，则需补充记录其与观测者、海岸线及冰缘的距离，以及动物的行进方向。针对每个目击位置，数据集需按物种分类上报所有观测到的海洋动物目击数据。可汇总上报所有目击动物的物种识别信息、总个体数，以及按年龄组（成体、亚成体、幼体、未知）划分的数量统计；也可按性别、行为、斑纹或其他特征划分的亚组进行细分统计。此外，数据集预留了文本记录字段用于添加备注信息。
