UK National Databank of Moored Current Meter Data (1967-)

The data set comprises more than 7000 time series of ocean currents from moored instruments. The records contain horizontal current speed and direction and often concurrent temperature data. They may also contain vertical velocities, pressure and conductivity data. The majority of data originate from the continental shelf seas around the British Isles (for example, the North Sea, Irish Sea, Celtic Sea) and the North Atlantic. Measurements are also available for the South Atlantic, Indian, Arctic and Southern Oceans and the Mediterranean Sea. Data collection commenced in 1967 and is currently ongoing. Sampling intervals normally vary between 5 and 60 minutes. Current meter deployments are typically 2-8 weeks duration in shelf areas but up to 6-12 months in the open ocean. About 25 per cent of the data come from water depths of greater than 200m. The data are processed and stored by the British Oceanographic Data Centre (BODC) and a computerised inventory is available online. Data are quality controlled prior to loading to the databank. Data cycles are visually inspected by means of a sophisticated screening software package. Data from current meters on the same mooring or adjacent moorings can be overplotted and the data can also be displayed as time series or scatter plots. Series header information accompanying the data is checked and documentation compiled detailing data collection and processing methods.

本数据集由超过7000条海洋环流的时间序列数据组成，这些数据源自锚定式仪器。记录中包含了水平流速和流向，以及通常伴随的温度数据。此外，还可能包含垂直速度、压力和电导率数据。数据主要源自大不列颠群岛沿海大陆架海域（例如北海、爱尔兰海、凯尔特海）以及北大西洋。同时，南大西洋、印度洋、北极洋、南大洋以及地中海的数据亦可供参考。数据收集始于1967年，并持续至今。采样间隔通常介于5至60分钟之间。在大陆架区域，流速仪的部署通常持续2至8周，而在开阔海洋中则可达6至12个月。约25%的数据来源于超过200米深的水域。数据由英国海洋数据中心（BODC）进行处理和存储，并可通过在线计算机化目录进行查询。在数据入库之前，对数据进行质量控制。通过高级筛选软件包对数据周期进行视觉检查。同一锚定或相邻锚定的流速仪数据可以进行叠加，并且数据也可以以时间序列或散点图的形式展示。伴随数据的系列头信息将进行核查，并编制详细说明数据收集和处理方法的文档。
