The data set comprises a series of ten reports containing tables of current data and diagrams of trajectories derived from neutrally buoyant floats deployed in seas across the globe. The floats were numbered between 1-180 and 209-227, with floats 1-180 being deployed between 1955 and 1964 and floats 209-227 being deployed between February and March 1969. Detailed deployment information is listed below, with deployment location, float numbers, deployment dates and ship name (if known). NE Atlantic: floats 1-5 (Jun 1955, Oct-Nov 1955); float 11 (Aug 1956); floats 12-20 (Mar 1957); floats 25-33 (May-Jul 1958); floats 34-39 (Nov 1958). Norwegian Sea: floats 6-10 (Apr-May 1956). NW Pacific: floats 21-24 (Jul-Aug 1957). Deep water off Bermuda: floats 40-53, 55, 58 (Jun-Oct 1959, RV Aries); floats 54, 56, 57 (Oct 1959, RV Crawford); floats 59-60,64-65,68, 69,71,73-74 (Jun-Dec 1959, RV Aries); floats 61-63,66, 67,70,72 (Nov 1959, RV Crawford); floats 75-77 (Dec 1959, RV Atlantis); floats 78-98 (Feb-Jun 1960, RV Aries); floats 99-119 (Jun-Aug 1960, RV Aries). Faroe-Shetland Channel: floats 120-127 (Jul 1961, RRS Discovery). Faroe Bank Channel: float 135 (1963, Ernest Holt). Labrador Sea: floats 128-132 (1962, Erika Dan). Arabian Sea: floats 133, 134, 136-139 (Jul-Aug 1963, RRS Discovery). Indian Ocean: floats 140-160 (Mar-Apr 1964, RRS Discovery); floats 161-180 (Apr-Aug 1964, RRS Discovery). NW Mediterranean: floats 209-227 (Feb-Mar 1969, RRS Discovery). The reports were produced by the National Institute of Oceanography (NIO), which later became the Institute of Oceanographic Sciences Deacon Laboratory.

The dataset comprises 2 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from the East Atlantic area specifically just North of the McGowan Seamount and the Kane Gap, East of Guinea, from January to April 1968. 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 National Institute of Oceanography.

The dataset comprises 17 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North East Atlantic Ocean (limit 40W) area specifically around Cape Verde and to the north east of the Canary Islands. The data were collected from February to April of 1972. 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 National Institute of Oceanography.

The dataset comprises 22 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Irish Sea and St. George's Channel and the North East Atlantic Ocean (limit 40W) area specifically both North and South of Loury Canyon, from April to June of 1971. 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 National Institute of Oceanography.

The dataset comprises 3 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North East Atlantic Ocean (limit 40W) area specifically west of Portugal and south of Palmer Ridge, from September to November of 1970. 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 National Institute of Oceanography.

The dataset comprises 4 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from the North East Atlantic Ocean (limit 40W) area specifically South East of the Santo Antao ridge, from October to December of 1969. 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 National Institute of Oceanography.
