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, 1982-09-04 to 1982-09-15 (NODC Accession 8300162)

Water physics and chemistry data were collected using moored current meter and bottle casts in the Northwest Atlantic Ocean from September 4, 1982 to September 15, 1982. Data were submitted by National Ocean Service (NOS) 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.

本数据集的水体理化数据采集于1982年9月4日至1982年9月15日的西北大西洋海域，采用锚定海流计与采水瓶采样两种方式完成。数据由美国国家海洋服务局（National Ocean Service, NOS）作为东北监测计划（North East Monitoring Program, NEMP）项目的组成部分提交。数据经美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理为NODC标准水体理化数据（F004）格式。完整的水体理化数据说明可通过以下网址查阅：http://www.nodc.noaa.gov/General/NODC-Archive/f004.html。

F004格式专用于存储水柱理化特征的实测与分析数据。可记录的化学参数涵盖盐度、pH值、溶解氧浓度、氨浓度、硝酸盐浓度、磷酸盐浓度、叶绿素浓度及悬浮颗粒物含量。可记录的物理参数包括温度、密度（σ-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，其中包括观测时刻研究区域的环境条件。
