Cloud amount/frequency, TRANSMISSIVITY and other data from BARTLETT in the Greenland Sea from 1989-09-07 to 1989-09-20 (NODC Accession 9200159)

The Conductivity, Temperature and Depth (CTD) and other data were collected in Greenland Sea. Data was collected from Ship BARTLETT. The data was collected over a period spanning from September 7, 1989 to September 20, 1989. Data was submitted in a tape by Mr. Robert H. Bourke, Naval Postgraduate School (NPS), Monterey CA. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC.

F022 High-resolution CTD data is collected from high resolution (conductivity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1 m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t) and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals.

本数据集包含格陵兰海域采集的电导率-温度-深度剖面仪（Conductivity, Temperature and Depth, CTD）及其他相关数据。数据采集自BARTLETT号科考船，采集时段为1989年9月7日至1989年9月20日。该数据由加州蒙特雷海军研究生院（Naval Postgraduate School, NPS）的Robert H. Bourke先生以磁带形式提交。数据已完成处理，可通过美国国家海洋数据中心（National Oceanographic Data Center, NODC）的F022-CTD-Hi Resolution文件格式获取。

F022系列高分辨率CTD数据采集自高分辨率电导率-温度-深度剖面仪。此类电子设备在海洋中布放与回收的过程中，可输出温度、盐度及其他参数的准连续剖面数据。数据值可经过平均、滤波处理，或通过插值方法生成，且可按照精度可达1米的深度间隔进行记录发布。每个测站均会记录航次与仪器信息、站位坐标、观测日期、时间及采样间隔。测次开展时的环境数据（包括气象与海面状况）同样可被纳入记录。数据记录包含指定深度或压力层级下的温度、盐度（或电导率）、密度（计算得到的sigma-t）数据，以及可能存在的溶解氧或透射率数据。数据可按照等间距或不等间距的深度或压力间隔进行发布。
