Marine bird habitat and other data from aircraft as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 17 May 1976 to 20 May 1976 (NODC Accession 7601876)

Marine bird habitat and other data were collected from aircraft from 17 May 1976 to 20 May 1976. Data were collected by the Alaska State Department of Fish and Game - Anchorage as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F040 Marine Bird Habitats 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 F040 format contains data from field observations of marine bird species and their associated habitats. The data are collected to provide information about species abundance, distribution and behavior. Position, date, time, elapsed survey time, area and distance, platform type and sampling technique are reported for each survey. Environmental information may include meteorological conditions, sea surface temperature and salinity, tide conditions and ice characteristics. Species and habitat information may include number of species, number of individuals per species, age, sex, color, molt, behavior, physiographic features, substrate, cover and distances to shore, barrier islands, or river deltas.

1976年5月17日至20日期间，海洋鸟类栖息地及其他相关数据通过航空器采集获得。本次数据采集由阿拉斯加州鱼类与野生动物局安克雷奇分局作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的一部分实施完成。数据经美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理，统一采用其制定的F040海洋鸟类栖息地标准格式存储。完整的格式说明文档可通过NODC官方网站www.nodc.noaa.gov获取。本次存档数据集的模拟文件可通过NODC用户服务部门获取。

F040格式收录了海洋鸟类物种及其关联栖息地的野外观测数据。本次数据采集旨在获取物种丰度、分布格局及行为特征相关信息。每份调查记录均包含观测位置、日期、时间、调查时长、调查区域与覆盖距离、观测平台类型及采样方法等核心信息。环境信息可涵盖气象条件、海表温度与盐度、潮汐状况及海冰特征等要素。物种与栖息地信息则包含物种总数、各物种个体数量、年龄、性别、羽色、换羽状态、行为特征、地貌要素、底质类型、生境覆盖情况，以及至岸线、障壁岛或河口三角洲的距离等内容。
