Marine Toxic Substance and other data from core casts from the ALUMINIAK in the Beaufort Sea as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 14 August 1977 to 25 August 1977 (NODC Accession 7900067)

Marine Toxic Substance and other data were collected from core casts in the Beaufort Sea from the ALUMINIAK. 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) from 14 August 1977 to 25 August 1977. 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.

本数据集涵盖海洋有毒物质及其他相关数据，数据采集自波弗特海（Beaufort Sea）海域由“ALUMINIAK”号科考船获取的岩心柱样。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，简称UAK/IMS）于1977年8月14日至1977年8月25日采集，作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program，简称OCSEAP）的组成部分。数据经美国国家海洋数据中心（National Oceanographic Data Center，简称NODC）按照NODC标准F144海洋有毒物质格式完成标准化处理。完整格式说明可通过NODC官网https://www.nodc.noaa.gov/General/NODC-Archive/f144.html查询获取，本存档数据集的模拟文件可通过NODC用户服务渠道获取。

F144格式存储的数据包含海洋环境中有毒物质及其他污染物的环境浓度信息，数据来源于水体、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污口附近区域，或是大范围海洋监测调查过程中获取。此外，数据集还可包含海滩焦油沉积的野外观测记录。调查相关信息包括作业平台类型、调查起止日期、调查人员及其所属机构。若样本采集自排污口附近，则需记录排污口位置、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其地理位置、采样日期、时间及现场环境条件。环境数据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、表层水温与盐度，以及浪高与浪周期。每份采集并完成分析的样本均需记录其特征、采集方法及实验室分析技术。数据记录包含所分析的每种化学物质的浓度值（或用于标识痕量物质的编码）。化学物质通过美国化学学会下属化学文摘社（Chemical Abstracts Service，简称CAS）分配的登记号对应编码进行标识。获取样本的海洋生物采用12位NODC分类编码进行识别。数据集附带文本记录字段，用于填写可选备注信息。
