Oceanographic station data from bottle casts from the SACKVILLE in the North Atlantic Ocean from 15 January 1963 to 18 January 1963 (NODC Accession 7600961)

Oceanographic station data were collected from the SACKVILLE in the North Atlantic Ocean. Data were collected by the St. Andrews Biological Station from 15 January 1963 to 18 January 1963. 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.

本数据集为采集自北大西洋海域SACKVILLE站位的海洋站观测数据，由圣安德鲁斯生物站于1963年1月15日至1963年1月18日期间完成采集。数据经NODC处理，适配至NODC标准站数据II输出格式（SD2）。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/sd2.html获取。
SD2格式包含在离散深度层级记录的物理化学海洋学数据。绝大多数观测采用多瓶式南森采水剖面或其他类型的水体采样器完成，仅约5%的观测数据通过电子CTD（电导率-温度-深度仪，conductivity-temperature-depth）或STD（盐度-温度-深度记录仪，salinity-temperature-depth）获取。不过，提交至NODC的CTD/STD数据的深度层级与南森采水剖面数据保持一致，且处理与存储流程与南森数据完全相同。每个站位均记录有航次信息（如船舶、所属国家、研究机构）、站位位置、观测日期与时间。核心观测参数为温度与盐度，同时也可记录溶解氧、磷酸盐、总磷、硅酸盐、硝酸盐、亚硝酸盐及pH值等指标。采样时的气象条件（如气温、气压、风向风速、海浪状况）亦可被记录，此外还包含水体颜色（福勒-乌勒色标，Forel-Ule scale）、水体透明度（塞氏盘深度，Secchi disk depth）及海底深度等辅助数据。密度（σ-t）、声速与动态深度异常等参数由实测数据计算得到。每个站位不仅包含观测深度层级处的实测数据，还包含经插值至标准深度层级后的数据集。
