Marine mammal specimen and other data from the Beaufort Sea and other locations from the SURVEYOR and other platforms as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 25 January 1977 to 17 November 1977 (NODC Accession 7900339)

Marine mammal specimen and other data were collected in the Beaufort Sea from the SURVEYOR and other platforms from 25 January 1977 to 17 November 1977. Data were collected by the Alaska State Department of Fish and Game as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F025 Marine Mammal Specimens format. Full format description ia available from the NODC homepage at www.nodc.noaa.gov/. An analog file for this accession is available from NODC user services. The F025 format is designed to support studies of biological populations and ecosystems that are subject to impact from oil and gas development, marine pollution and other environmental disturbances. Information on marine animal populations, activities, migratory routes and breeding locales are obtained from either surface ship or aircraft surveys. The F025 format contains data from examinations of marine mammal specimens. The data are collected to define behavior, population dynamics and trophic relationships of marine mammals. In addition to species, position, time and environmental conditions at the collection site, data for each specimen may include weight and body dimensions, sex and reproductive status, age, primary cause of death and analysis of stomach contents. The species of both the specimen and its ingested prey are encoded using the NODC Taxonomic Code. Comments may be reported in a free-text record.1977年1月25日至11月17日，研究团队在波弗特海（Beaufort Sea）通过勘测者号（SURVEYOR）考察船及其他平台采集了海洋哺乳动物标本及相关数据。该数据由阿拉斯加州鱼类与狩猎部（Alaska State Department of Fish and Game）作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的一部分开展采集工作，后由美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照NODC标准F025海洋哺乳动物标本格式进行处理。完整格式说明可从NODC官网www.nodc.noaa.gov获取，本次入库数据集的模拟文件可通过NODC用户服务获取。 F025格式旨在支撑受油气开发、海洋污染及其他环境扰动影响的生物种群与生态系统研究。海洋动物的种群情况、活动规律、洄游路线及繁殖栖息地等信息，均可通过水面船舶或航空勘测获取。 F025格式收录海洋哺乳动物标本的检测数据，采集这些数据的目的在于阐明海洋哺乳动物的行为特征、种群动态及营养级关系。除采集地点的物种信息、位置、时间及环境条件外，每份标本的数据还可包括体重、身体尺寸、性别及繁殖状态、年龄、主要致死原因以及胃容物分析结果。标本及其摄食猎物的物种信息均采用NODC分类编码（NODC Taxonomic Code）进行标注，同时可通过自由文本记录添加相关备注。
