This dataset comprises 51 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during June - July 1998 from stations at La Chapelle Bank in the Bay of Biscay and off the coast of Vigo, Spain. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the University of Liège Department of Astrophysics Geophysics and Oceanography as part of the Ocean Margin Exchange (OMEX) II project.

The data set comprises hydrographic and biogeochemical and biological measurements including temperature, salinity, currents, chlorophyll, dissolved organic and inorganic carbon and nitrogen, suspended matter concentrations, nutrients, plankton and fish. The results of primary production experiments are also included. The data were collected from the Bristol Channel, Severn Estuary, Celtic Sea and Plymouth Sound between 1971 and 1983. Measurements were taken over a series of more than 100 cruises, many with more than 50 stations. The most intensive sampling took place before 1975. The original data were collated and stored at Institute for Marine Environmental Research (IMER), which became Plymouth Marine Laboratory in 1988. As this is a large and important data set, which was previously held in an inaccessible format, it was selected for long-term archival at BODC as part of the NERC SEEDCORN programme. The data have been extracted, loaded into a relational database and are available on CD-ROM.

This dataset comprises 167 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during August - October 1994 from stations from the Straits of Hormuz to the Murray Ridge in the Gulf of Oman and the Arabian Sea. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Plymouth Marine Laboratory as part of the ARABESQUE project.

This dataset comprises 57 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in June 1997 from stations off the coast of the Iberian Peninsula. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Vrije Universiteit Brussels Department of Analytical and Environmental Chemistry as part of the Ocean Margin Exchange (OMEX) II project.

This dataset comprises 50 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in September 1999 from stations off the coast of the Iberian Peninsula, between 42.0 - 43.0 N, 9.0 - 10.3 W.
