资源简介:

Oceanographic Station Data, temperature, and other data were collected using CTD and bottle casts from NOAA Ship DAVID STARR JORDAN, NOAA Ship McARTHUR, and NEW HORIZON from the Coastal Waters of California from February 19, 1985 to November 14, 1985. Data were submitted by Scripps Institution of Oceanography as part of the California Cooperative Fisheries Investigation (CALCOFI) project. Data were processed by NODC to the NODC standard Oceanographic Station Data (SD2) and the Universal Bathythermograph Output (UBT) formats. Full format descriptions are available at nodc.noaa.gov/. The Oceanographic Station Data 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.

本数据集包含海洋站数据、温度及其他海洋学相关数据,采集于1985年2月19日至1985年11月14日的加利福尼亚近岸海域,采集平台为美国国家海洋和大气管理局(NOAA)旗下的DAVID STARR JORDAN号科考船、McARTHUR号科考船以及NEW HORIZON号科考船,采集手段为电导率-温度-深度仪(CTD, Conductivity-Temperature-Depth)与采水器挂站(bottle casts)。数据由斯克里普斯海洋研究所(Scripps Institution of Oceanography)作为加利福尼亚合作渔业调查(California Cooperative Fisheries Investigation, CALCOFI)项目的组成部分提交,后经国家海洋数据中心(National Oceanographic Data Center, NODC)处理,转换为NODC标准海洋站数据格式(SD2)与通用海水温度深度记录仪输出格式(UBT)。完整格式说明可访问nodc.noaa.gov网站获取。 海洋站数据格式涵盖离散深度层级下记录的物理化学类海洋学观测数据。绝大多数观测采用多瓶南森式采水器(multi-bottle Nansen casts)或其他类型水样采集器完成,仅约5%的少量数据通过电子CTD(conductivity-temperature-depth,电导率-温度-深度)或盐度-温度-深度仪(STD, Salinity-Temperature-Depth)记录仪获取。不过,CTD/STD数据将按照与南森采水数据一致的深度层级上报至NODC,并与南森采水数据采用完全相同的流程进行处理与存储。每个测站均记录有航次相关信息(如科考船、所属国家与依托科研机构)、站位地理坐标、观测日期与时间。核心测量参数为温度与盐度,同时可能上报溶解氧、磷酸盐、总磷、硅酸盐、硝酸盐、亚硝酸盐及pH值。采水作业时的现场气象条件(如气温、气压、风向风速、海浪状况)也可被同步记录,此外还包含水体颜色(福勒-于勒色度标尺,Forel-Ule scale)、水体透明度(塞氏盘深度,Secchi disk depth)及海底水深等辅助数据。密度(sigma-t)、声速与动态深度异常值可通过实测参数计算得到。每个测站既包含实测深度层级的原始测量数据,也包含经插值得到的标准深度层级数据集。
