Oceanographic station data from bottle casts from the INGHAM from Ocean Weather Station E (OWS-E) in the North Atlantic Ocean 05 June 1973 to 30 June 1973 (NODC Accession 7400028)

Oceanographic station data were collected from the INGHAM within a 1-mile radius of Ocean Weather Station E (3500N 0480W) and in transit. Data were collected by the United States Coast Guard (USCG) from 05 June 1973 to 30 June 1973. Data were processed by NODC to the NODC standard Station Data II Output Format (SD2). Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/sd2.html.

The SD2 format contains physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5 percent) were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters and temperature and salinity , but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t) sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels.

本数据集为海洋站观测数据，采集自“英厄姆号”（INGHAM）在E号海洋气象站（北纬35°00′，西经48°00′）周边1英里范围内及航行途中的海域。数据由美国海岸警卫队（United States Coast Guard, USCG）于1973年6月5日至1973年6月30日期间采集。国家海洋数据中心（National Oceanographic Data Center, NODC）将所有数据处理为NODC标准站数据II输出格式（Station Data II Output Format, SD2）。完整格式说明可从NODC获取，网址为www.nodc.noaa.gov/General/NODC-Archive/sd2.html。

SD2格式包含离散深度层级下记录的物理化学海洋学数据。多数观测采用多瓶南森采水器（multi-bottle Nansen casts）或其他类型水体采样器完成，仅约5%的少量数据通过电子电导率-温度-深度（conductivity-temperature-depth, CTD）仪或盐度-温度-深度（salinity-temperature-depth, STD）记录仪获取。不过，CTD/STD数据以与南森采水数据一致的深度层级提交至NODC，并按照与南森采水数据完全相同的流程完成处理与存储。每一个海洋站均会记录航次相关信息（如船舶、所属国家、研究机构）、站位坐标、观测日期与时间。核心观测参数为温度与盐度，但也可同步记录溶解氧、磷酸盐、总磷、硅酸盐、硝酸盐、亚硝酸盐及pH值。采水作业时的气象条件（如气温、气压、风向风速、浪况）亦可被记录，辅助数据则包括水体颜色（福勒-于勒色标，Forel-Ule scale）、水体透明度（塞氏盘深度，Secchi disk depth）及海底深度等。密度（西格玛-t，sigma-t）、声速与动态深度异常值均可通过实测参数计算得到。每个海洋站既包含实测深度层级下的原位观测数据，同时也包含经插值得到的标准化深度层级数据集。
