Chemical data from moored current meter, bottle casts, and other instruments in the Coastal Waters of New Jersey as part of the Mesa New York Bight (MESA - NYB) project, 18 May 1978 - 19 October 1978 (NODC Accession 7900280)

Chemical data were collected using moored current meter, bottle casts, and other instruments in the Coastal Waters of New Jersey from May 18, 1978 to October 19, 1978. Data were submitted by Nassau County Department of Health; Bureau of Water Surveillance as part of the Mesa New York Bight (MESA - NYB) project. Data has been been processed by NODC to the NODC standard F004- Current Meter Data, and F144 Marine Toxic Substances formats. Full format descriptions are available from NODC homepage at http://www.noaa.nodc.gov

The F004 format is used for data from measurements and analyses of physical and chemical characteristics of the water column. Among chemical parameters that may be recorded are salinity, PH, and concentration of oxygen, ammonia, nitrate, phosphate, chlorophyll, and suspended solids. Physical parameters that may be recorded include temperature, density (sigma-t), transmissivity, and current velocity (east-west and north-south components). Cruise and station information, including environmental conditions of the study site at the time of observations, is also included.

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18日至10月19日，研究团队于新泽西海近岸海域，利用锚定海流计（moored current meter）、采水器（bottle casts）及其他仪器采集化学数据。本数据集由拿骚县卫生署（Nassau County Department of Health）水域监测局（Bureau of Water Surveillance）作为纽约湾梅萨（Mesa New York Bight, MESA-NYB）项目的一部分提交。数据集已由美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照其标准格式F004-海流计数据（Current Meter Data）与F144-海洋有毒物质（Marine Toxic Substances）进行标准化处理。完整的格式说明可从NODC官网http://www.noaa.nodc.gov获取。

F004格式用于存储水柱物理与化学特性的实测及分析数据。可记录的化学参数包括盐度、pH值、溶解氧、氨氮、硝酸盐、磷酸盐、叶绿素以及悬浮固体浓度；物理参数则涵盖温度、密度（σ_t）、透射率以及海流流速（东西向与南北向分量）。此外，数据集还包含航次与测站信息，以及观测时研究区域的环境条件。

F144格式用于存储海洋环境中有毒物质与其他污染物的原位浓度数据。此类数据源自水体、沉积物或海洋生物样本的实验室分析。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。此外，数据集还可包含海滩焦油沉积的野外观测记录。调查信息涵盖观测平台类型、起止日期、调查人员及所属机构。若数据采集自排污口附近，则需报告排污口位置、水深、离岸距离、平均排放量及其他相关特征。每个样本测站均需记录其位置、日期、时间及环境条件。环境数据可包括气象与海面状况、潮汐潮位与潮高、温跃层或混合层深度、表层温度与盐度，以及浪高与波周期。针对每一份采集并分析的样本，均需记录其样本特征、采集方法及实验室分析技术。数据记录包含每种被测化学物质的浓度值（或用于表示痕量含量的编码）。化学物质通过美国化学学会（American Chemical Society）化学文摘社（Chemical Abstracts Service, CAS）分配的登记号对应的编码进行标识。采样所用海洋生物则采用12位NODC分类编码（NODC Taxonomic Code）进行识别。此外，数据集还支持可选的文本注释记录。
