Marine bird sighting and other data from aircraft as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 19 August 1975 to 11 October 1976 (NODC Accession 7700651)

Marine bird sighting and other data were collected from aircraft from 19 August 1975 to 11 October 1976. Data were collected by the College of the Atlantic 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.1975年8月19日至1976年10月11日，研究人员依托航空器采集了海鸟目击数据及其他关联数据。本次数据采集工作由大西洋学院（College of the Atlantic）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。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将采集所得数据整理为符合NODC标准的F033海鸟目击、船舶/航空器普查格式。完整的格式说明可通过NODC官方网站www.nodc.noaa.gov获取。本存档批次的模拟文件可通过NODC用户服务渠道获取。 F033格式存储了沿船舶或航空器调查航线开展的海鸟野外观测数据，其采集目的是为海鸟种群密度与分布情况提供信息支撑。每份调查记录均需报告起止位置、观测日期与耗时、航速与航向、观测平台类型以及观测技术手段等核心信息。环境相关信息可涵盖气象与海表状况、距岸线及陆架坡折的距离、各断面内外的冰情特征，以及包括浮油在内的海面漂浮物情况。物种数据可包含个体年龄、性别、体色、羽饰、种群数量、飞行方向、行为模式以及食物源关联信息。单次观测时段内可记录任意数量的海鸟物种信息。
