Marine toxic substance and other data from bottle casts from the DISCOVERER as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 05 May 1978 to 16 May 1978 (NODC Accession 7900274)

Marine toxic substance and other data were collected from bottle casts from the DISCOVERER from 05 May 1978 to 16 May 1978. Data were collected by the Pacific Marine Environmental Laboratory (PMEL) as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC standard F144 Marine Toxic Substances format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f144.html. An analog file for this accession is available from NODC user services.

The F144 format contains data on ambient concentrations of toxic substances and other pollutants in the marine environment. The data derive from laboratory analyses of samples of water, sediment, or marine organisms. Samples may have been collected near marine discharge sites or during ocean monitoring surveys of large areas. Field observations of tar deposits on beaches may also be reported. Survey information includes platform type, start and end dates, and investigator and institution. If data are collected near a discharge site, discharge location, depth, distance to shore, average volume, and other characteristics are reported. Position, date, time and environmental conditions are reported for each sample station. Environmental data may include meteorological and sea surface conditions, tide stage and height, depth of the thermocline or mixed layer surface temperature and salinity, and wave height and periods. Sample characteristics, collection methods, and laboratory techniques are reported for each sample collected and analyzed. The data record comprises concentration values (or a code to indicate trace amounts) for each chemical substance analyzed. Chemical substances are identified by codes based on the registry numbers assigned by the Chemical Abstracts Service (CAS) of the American Chemical Society. Marine organisms from which samples have been taken are identified using the 12-digit NODC Taxonomic Code. A text record is available for optional comments.

1978年5月5日至5月16日，科研人员依托“发现者”号（DISCOVERER）开展瓶式采样作业，收集了海洋有毒物质及其他相关数据。该数据集由太平洋海洋环境实验室（Pacific Marine Environmental Laboratory, PMEL）作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的组成部分采集完成。美国国家海洋数据中心（National Oceanographic Data Center, NODC）已按照其制定的F144海洋有毒物质标准格式对数据完成标准化处理。完整的格式说明文档可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f144.html查询获取。本入藏数据集的模拟文件可通过NODC用户服务渠道获取。

F144格式涵盖海洋环境中有毒物质与其他污染物的环境浓度数据。此类数据源自水体、沉积物或海洋生物样本的实验室分析结果。样本可采集自海洋排放点附近，或是大范围海洋监测调查过程中。此外，报告内容还可包含海滩焦油沉积的现场观测记录。
调查信息涵盖平台类型、调查起止日期、调查人员及其所属机构。若样本采集自排放点附近，则需同步报告排放点位、水深、离岸距离、平均排放量及其他相关特征参数。每个采样站位均需记录其地理位置、采集日期、时间及现场环境条件。环境数据可涵盖气象与海面状况、潮汐水位与潮高、温跃层或混合层深度、海面温度与盐度，以及浪高与浪周期。针对每一份采集并完成实验室分析的样本，需记录其样本特征、采集方法及分析技术细节。数据记录包含每一种被分析化学物质的浓度值（或用于标识痕量含量的编码）。化学物质通过美国化学学会（American Chemical Society）下属化学文摘社（Chemical Abstracts Service, CAS）分配的登记号进行编码标识。采集样本的海洋生物采用12位NODC分类代码进行唯一标识。可附加文本记录以填写可选备注信息。
