Marine bird sightings from aircraft, temperature profiles from XBT casts, and other data from the YANKEE CLIPPER and other platforms as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 02 December 1969 to 28 June 1977 (NODC Accession 7700893)

Marine bird sightings from aircraft, temperature profiles from XBT casts, and other data were collected from the YANKEE CLIPPER and other platforms from 02 December 1969 to 28 June 1977. Data were collected by the Fish and Wildlife Service (FWS) and the Hydrographic Office, Ministry of Defence, 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 and the Universal Bathythermograph Output formats. Full format descriptions are 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.

The UBT format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record are comprised of pairs of temperature-depth values. The XBT data files contain temperature values at non-uniform depths. These depths were recorded at the minimum number of points (''''inflection points'''') required to accurately define the temperature curve.
Standard XBTs can obtain profiles to depths of either 450 or 760 m.

1969年12月2日至1977年6月28日期间，科研人员从“扬基克利珀”号（YANKEE CLIPPER）及其他观测平台采集了航空海鸟目击记录、抛弃式温深计（XBT）投放得到的温度剖面数据及其他相关数据。本次数据采集由鱼类与野生动物管理局（FWS）以及英国国防部水文局执行，属于外大陆架环境评估计划（OCSEAP）的一部分。数据由国家海洋数据中心（NODC）按照NODC标准F033海鸟目击、船舶/航空普查格式以及通用温深计（UBT）输出格式进行处理。完整的格式说明可从NODC官网www.nodc.noaa.gov/获取。本次数据集的模拟文件可通过NODC用户服务渠道获取。

F033格式存储的是沿船舶或航空调查航线开展的海鸟野外观测数据。此类数据采集目的为获取海鸟种群密度与分布情况的相关信息。每份调查记录均会报告起止位置、日期、耗时、航速与航向、观测平台类型及观测手段。环境信息可涵盖气象与海表状况、距海岸线及陆架坡折的距离、各断面内外的海冰特征，以及包括浮油在内的海面漂浮碎屑。物种相关数据可包含海鸟的年龄、性别、体色、羽衣特征、个体数量、飞行方向、行为模式以及与食物源的关联。单次观测时段内可报告任意数量的物种观测记录。

通用温深计（UBT）格式存储的是使用抛弃式温深计（XBT）获取的温度-深度剖面数据。每份观测记录均会报告航次信息、位置、日期与时间。数据记录由温度-深度值对组成。XBT数据文件存储的是非等间隔深度处的温度值。这些深度点以准确刻画温度曲线所需的最少点数（即拐点）进行记录。标准XBT可获取深度达450米或760米的温度剖面。
