Zooplankton and other data from net casts from the ACONA and other platforms as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 02 July 1974 to 15 May 1975 (NODC Accession 7601458)

Zooplankton and other data were collected from net casts from the ACONA and other platforms from 02 July 1974 to 15 May 1975. Data were collected by the University of Alaska - Fairbanks; Institute of Marine Science (UAK/IMS) as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F124 Zooplankton Data format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f124.html. An analog file for this accession is available from NODC user services.

The F124 format is used for data from sampling and analysis of marine zooplankton. Information on zooplankton abundance, distribution, and productivity derived from these data support studies of marine populations and ecosystems. Data reported may include: cruise information, position, date, and time of sampling; bottom depth, sampling depths, temperature, and salinity; gear type, volume of water filtered, total dry and wet weight, and other data for total haul; and data for subsamples by species. Data on zooplankton catch by species may include subsample size, zooplankton concentration, life history code, and numbers of adults, juveniles, eggs, and larvae. Estimated density of holoplankton and meroplankton and data on ichthyoplankton may also be reported. A text record is available for comments. Note: there are two options for reporting subsample counts of individuals at different life history stages. If life history codes are used, only number of adults should be reported on that record. Additional separate records should then be used to report number of juveniles and so on. Alternatively, life history codes may not be used and number of adults, juveniles, and so entered in the proper fields of a single record.

1974年7月2日至1975年5月15日期间，研究人员通过ACONA及其他平台的网采作业，收集了浮游动物(Zooplankton)及其他相关数据。该数据由阿拉斯加大学费尔班克斯分校海洋科学研究所（UAK/IMS）作为外大陆架环境评估计划(OCSEAP)的一部分采集完成。数据随后由国家海洋数据中心(NODC)处理为NODC标准F124浮游动物数据格式。完整的格式说明文档可通过NODC官方网站www.nodc.noaa.gov/General/NODC-Archive/f124.html获取。本次入库数据集的模拟文件可通过NODC用户服务渠道获取。

F124格式专用于海洋浮游动物的采样与分析数据。从该数据集提取的浮游动物丰度、分布及生产力信息，可为海洋种群与生态系统研究提供关键支撑。可上报的数据内容包括：航次信息、采样位置、采样日期与时间；海底深度、采样深度、水温及盐度；采样设备类型、过滤水体体积、总拖网样品的总干重与湿重及其他相关参数；以及按物种分类的子样本数据。按物种统计的浮游动物捕捞数据可包含：子样本规格、浮游动物浓度、生活史代码，以及成体、幼体、卵和幼虫的个体数量。此外，还可上报终生浮游生物(holoplankton)与阶段性浮游生物(meroplankton)的估算密度，以及鱼卵仔鱼(ichthyoplankton)相关数据。数据集附带可填写备注的文本记录字段。注意：针对不同生活史阶段的个体子样本计数，存在两种上报方式：若使用生活史代码，则单条记录仅可填报成体数量，幼体等其他生活史阶段的个体数量需通过额外的独立记录上报；若不使用生活史代码，则可将成体、幼体等各类群的个体数量直接填入单条记录的对应字段中。
