Water physics and chemistry data from moored current meter and bottle casts in the Northwest Atlantic Ocean as part of the North East Monitoring Program (NEMP) project, 21 April 1980 - 18 July 1980 (NODC Accession 8100501)

Water physics and chemistry data were collected using moored current meter and bottle casts in the Northwest Atlantic Ocean from April 21, 1980 to July 18, 1980. Data were submitted by Atlantic Oceanographic Meterological Laboratory - Miami, FL. as part of the North East Monitoring Program (NEMP) project. Data were processed by NODC to the NODC standard Water Physics and Chemistry Data (F004) format. Full water physics and chemistry descriptions are available at http://www.nodc.noaa.gov/General/NODC-Archive/f004.html.

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.

本数据集的水体物理与化学数据采集于1980年4月21日至1980年7月18日的西北大西洋海域，采用锚定海流计（moored current meter）与采水器（bottle casts）完成数据采集。数据由美国佛罗里达州迈阿密大西洋海洋气象实验室（Atlantic Oceanographic Meteorological Laboratory - Miami, FL）提交，作为东北监测计划（North East Monitoring Program, NEMP）项目的组成部分。后续由国家海洋数据中心（NODC）按照NODC标准水体物理与化学数据（F004）格式完成数据处理。完整的水体物理与化学数据说明可通过以下链接获取：http://www.nodc.noaa.gov/General/NODC-Archive/f004.html。

F004格式专用于存储水柱物理与化学特征的实测与分析数据。可记录的化学参数包括盐度、pH值、溶解氧浓度、氨氮浓度、硝酸盐浓度、磷酸盐浓度、叶绿素浓度以及悬浮固体浓度。可记录的物理参数则涵盖水温、势密度（sigma-t）、透射率以及海流流速（东西向与南北向分量）。数据集同时包含航次与测站信息，其中包括观测时段内研究区域的环境条件。
