Marine toxic substance and other data from the Gulf of Alaska from the MOANA WAVE as part of the Outer Continental Shelf Environmental Assessment Program from 25 June 1976 to 078 July 1976 (NODC Accession 7601849)

Marine toxic substance and other data were collected in the Gulf of Alaska from the MOANA WAVE. Data were collected by Pacific Marine Environmental Laboratory (PMEL) as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 25 June 1976 to 08 July 1976. Data were processed by NODC to the NODC standard F144 Marine Toxic Substances and Pollutants 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 located at NODC in Silver Spring, MD. 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.本数据集的海洋有毒物质及其他相关数据采集于阿拉斯加湾的MOANA WAVE平台。该数据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）的一部分，于1976年6月25日至7月8日完成采集。数据已由国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准F144海洋有毒物质与污染物格式。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f144.html获取。本数据集的模拟文件存档于马里兰州银泉市的NODC。 F144格式涵盖海洋环境中有毒物质及其他污染物的环境浓度数据。此类数据源自对水体、沉积物或海洋生物样本的实验室分析。样本可采集自海洋排污口附近，或是大范围海洋监测调查期间。海滩焦油沉积的现场观测数据亦可纳入收录。调查信息包含作业平台类型、调查起止日期、调查人员及所属机构。若数据采集于排污口附近，则需记录排污位置、水深、离岸距离、平均排放量及其他相关特征。每个采样站位均需记录位置、日期、时间及环境条件。环境数据可涵盖气象与海表状况、潮汐水位与潮高、温跃层或混合层深度、海表温度与盐度，以及浪高与周期。每份采集并分析的样本，其特征、采集方法及实验室处理技术均有详细记录。数据记录包含各分析化学物质的浓度值（或用于指示痕量检出的代码）。化学物质通过美国化学学会下属化学文摘社（Chemical Abstracts Service, CAS）分配的登记号进行唯一标识。采集样本的海洋生物采用12位NODC分类代码进行识别。此外还提供可选的文本记录，用于添加附加备注。
