Description 
Summary

This data set has been compiled from data collected by many different groups within the Laboratory, from a variety of platforms, over the last century. The data set can best be described as three component parts: a) Data from 1960 to the end of 1999: these data are stored on optical disk and in manuscript form. The data have been fully checked and verified and comprise some 28,680 stations. b) Data from the Faroe-Shetland Channel from 1893 to 1959: these data are stored on optical disk and in manuscript form. The data have been verified. There are approximately 2000 stations. c) All other data prior to 1960: These data are stored in manuscript form in the original station books and other record sheets. During 1997 these data have been recovered from the station books into computer files and are yet to be formatted to the MLA format. There are some 19,000 stations. Each station is described by station number, its position (latitude and longitude), date and time of sampling, sounding, research vessel code, cruise number and sampled depths. In the main, the data from each station comprises depth, temperature and salinity. Depending on the area worked, and the requirements of the particular cruise, some or all of the additional parameters may have been measured. All the data in this data set have been collected under many different projects and programmes in which the Laboratory has been involved with the exception of approximately 600 stations from the Faroe-Shetland Channel. These data were obtained through the ICES Oceanography Secretary and originate from Denmark, Norway and the former USSR.
