Primary productivity, nutrients, and other data from bottle casts from the NOAA Ship DISCOVERER as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 18 May 1975 to 20 June 1975 (NODC Accession 7601624)

Primary productivity, nutrients, and other data were collected from bottle casts from the NOAA Ship DISCOVERER from 18 May 1975 to 20 June 1975. Data were collected by the University of Alaska - Fairbanks; Institute of Marine Science (UAK/IMS) as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F029 Primary Productivity format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f029.html. An analog file for this accession is available from NODC user services.

The F029 format contains data from measurements of primary productivity. The data are collected to provide information on nutrient levels and nutrient flow in offshore areas. In addition to cruise information, position, date, time, sampling depths, bottom depth, and environmental information, this file may contain measured parameters including: concentrations of nutrients such as phosphate, nitrate, silicate, and ammonia; temperature and salinity; and carbon assimilation. Measurements of chlorophyll A, phaeopigment, and carbon assimilation may be reported as integrated values. A free-text record is available for comments.

1975年5月18日至6月20日期间，研究人员借助美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）“发现者”号考察船的采水器采样，获取了初级生产力、营养盐及其他相关观测数据。该数据由阿拉斯加大学费尔班克斯分校海洋科学研究所（University of Alaska Fairbanks - Institute of Marine Science, UAK/IMS）作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的一部分采集完成。美国国家海洋数据中心（National Oceanographic Data Center, NODC）将全部数据整理为NODC标准F029初级生产力格式（F029 Primary Productivity Format）。完整的格式说明可通过NODC官方网站（www.nodc.noaa.gov/General/NODC-Archive/f029.html）查阅获取。本次入库数据集的模拟文件可通过NODC用户服务部门获取。

F029初级生产力格式包含初级生产力的实测数据，其采集目标为获取近海区域的营养盐水平与营养盐循环相关信息。除航次基本信息、站位坐标、观测日期与时间、采样深度、海底深度及环境参数外，该数据集文件还涵盖以下实测参数：磷酸盐、硝酸盐、硅酸盐、氨等营养盐浓度，水温与盐度，以及碳同化量。叶绿素a、脱镁色素及碳同化量的实测数据可报告为积分值。数据集附带自由文本注释记录。
