Marine bird sighting and other data from aircraft and other platforms as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 07 March 1977 to 19 September 1977 (NODC Accession 7800158)

Marine bird sighting and other data were collected from aircraft and other platforms from 07 March 1977 to 19 September 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 F033 Marine Bird Sighting, Ship/Aircraft Census format. Full format description is available from NODC at www.nodc.noaa.gov/. An analog file for this accession is available from NODC user services.

The F033 format contains data from field observations of marine birds made along ship or aircraft survey tracks. These data are collected to provide information on population density and distribution. Start and end position, date and elapsed time, speed and course, platform type and observing techniques are reported for each survey. Environmental information may include meteorological and sea surface conditions, distances to the shoreline and shelf break, ice characteristics within and outside each transect and surface debris, including oil slicks. Species data may include age, sex, color, plumage, number of individuals, direction of flight, behavior and food source association. Any number of species may be reported within one observation time span.

1977年3月7日至1977年9月19日期间，阿拉斯加州鱼类与野生动物部通过航空器及其他观测平台，收集了海洋鸟类目击记录及其他相关数据。本次数据采集工作作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的组成部分实施。美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照其制定的F033海洋鸟类目击、船舶/航空器普查标准格式对采集到的数据进行了标准化处理。完整的格式说明可通过NODC官方网站www.nodc.noaa.gov查询获取。本次数据集的模拟文件可通过NODC用户服务渠道申领。
F033格式收录了沿船舶或航空器调查航线开展的海洋鸟类野外观测数据，本次数据采集旨在获取海洋鸟类的种群密度与分布情况相关信息。每项调查均会记录起止位置、观测日期、耗时、航速与航向、观测平台类型及观测方法等关键参数。环境相关信息可涵盖气象与海表状况、距海岸线及陆架坡折的距离、各调查断面内外的冰情特征，以及包括浮油在内的海面漂浮废弃物等内容。物种相关数据则可包含鸟类的年龄、性别、羽色、羽毛状态、个体数量、飞行方向、行为模式及与食物源的关联等细节。在单次观测时段内，可记录任意数量的鸟类物种观测数据。
