UK National Databank of conductivity-temperature-depth (CTD) or salinity-temperature-depth (STD) profiles (1969-)

The databank comprises more than 60,000 profiles of conductivity-temperature-depth (CTD) or salinity-temperature-depth (STD) profiles collected during 100s of research cruises by UK laboratories, since 1969. In addition to water column temperature and salinity, some profiles may include measurements for nutrients, dissolved gases, pigments, or suspended particulate material. The majority of profiles were collected in the North East Atlantic or the shelf seas (often around the UK) but data are available from elsewhere including for example the Indian Ocean, the South Atlantic and the Southern Ocean. Many profiles have been measured in the shallow waters of the UK continental shelf but some are deep ocean profiles which may contain data to a depth of 5000m. Data are normally supplied to the British Oceanographic Data Centre as time or depth averages resulting in vertical resolutions between 0.5 dbar and 10 dbar, with casts collected in shallow water typically having a higher vertical resolution.

该数据库汇集了自1969年以来，英国实验室在数百次研究航次中收集的超过60,000个电导率-温度-深度（CTD）或盐度-温度-深度（STD）剖面样本。除了水温与盐度之外，部分剖面样本还记录了营养物质、溶解气体、色素或悬浮颗粒物的测量数据。绝大多数剖面样本是在东北大西洋或大陆架海域（通常位于英国周边）收集的，但数据资源亦涵盖其他地区，例如印度洋、南大西洋和南半球海域。众多剖面样本采集于英国大陆架的浅水区域，而部分则为深海剖面，其数据可延伸至5000米深度。数据通常以时间或深度平均值的形式提交至英国海洋数据中心，从而形成0.5 dbar至10 dbar之间的垂直分辨率，浅水区域的采集样本通常具有更高的垂直分辨率。
