Marine bird colony and other data from platforms in the Bering Sea as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 15 June 1975 to 15 October 1976 (NODC Accession 7700654)

Marine bird colony and other data were collected from platforms in the Bering Sea from 15 June 1975 to 15 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 F035 Marine Bird Colony format. Full format description is available from the NODC homepage at www.nodc.noaa.gov/. An analog file for this accession is available from NODC user services.

The F034 format contains data from field observations of marine birds made along land survey tracks. These data are collected to provide information on population density and distribution and breeding locales. The contents and structure of data type file are similar to Marine Bird Sighting, Aircraft Census (F033), although the transect distance of land surveys will normally be shorter than that of ship and aircraft surveys. In this data type the investigator defines the lateral dimension of survey distance unit (a specified number of whole meters). Start and end position, date and elapsed time, and number of distance units are reported for each survey. Environmental information may include meteorological and adjacent sea surface conditions, distance to nearest shoreline, ice characteristics, and debris, including oil slicks. Species data may include age, sex, color, plumage, number of individuals, flight direction, behavior, and food source association. Any number of species may be reported within one observation time span.

1975年6月15日至1976年10月15日期间，研究人员于白令海的观测平台上收集了海鸟繁殖群及其他相关数据。本数据集由大西洋学院（College of the Atlantic）作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的一部分开展采集工作。国家海洋数据中心（National Oceanographic Data Center, NODC）将所有数据处理为NODC标准F035海鸟繁殖群格式。完整的格式说明可通过NODC官方网站www.nodc.noaa.gov查阅。本数据集的模拟文件可通过NODC用户服务渠道获取。

F034格式存储了沿陆地调查航线开展的海鸟野外观测数据。采集此类数据旨在获取海鸟种群密度、分布范围及繁殖栖息地的相关信息。该数据类型文件的内容与结构与“海鸟观测、航空普查（F033）”高度相似，但陆地调查的样带距离通常短于船舶与航空调查的样带距离。在此数据类型中，调查人员需自行定义调查距离单元的横向范围（即指定整数米数）。每次调查需记录起始与终止位置、观测日期、耗时以及距离单元总数。环境信息可涵盖气象与邻近海面状况、距最近海岸线的距离、海冰特征以及包括浮油在内的海洋废弃物。物种相关数据可包含个体年龄、性别、体色、羽色、种群数量、飞行方向、行为模式以及食物来源关联信息。单次观测时段内可记录任意数量的物种数据。
