  • The data set comprises 2193 profiles of turbidity from an area of the Severn Estuary (UK) between the Shoots and Bridgwater Bay between 1974 and 1978. The data were collected as analogue records of continuous vertical profiles on a time series cross-section basis, where possible, over 13.5 hours from a drifting ship. All measurements were collected between 0 m and 39 m depth. The data coverage is derived from 172 stations along 17 survey lines, the density of coverage varying between 1 and 99 records per station. Each analogue record was digitised as approximately 200 pairs of XY coordinates. The X ordinates were then converted to depth (in metres) using a depth calibration and the Y ordinates to parts per million (PPM) of sediment using siltmeter calibration data. The Fluid Mud data bank was designed by the (former) Institute of Oceanographic Sciences (IOS) Taunton, UK, and the data were originally stored at IOS on a PDP 11 computer. They were then moved to an Oracle RDBMS at the British Oceanographic Data Centre (BODC) and stored as the Bristol Channel Suspended Sediments Data Bank.

  • This document describes CTD data collected on three cruises undertaken within the Dogger Bay Bank between August and November 2004, the RV Endeavour 12/04 (September 30 – October 10), 13/04 (August 31 – September 04) and 14/04 (October 22 – November 01). Ship-deployed CTDs were used to collect data at stations throughout each of the cruises. The cruises formed the research component of CEFAS project A1225 – North Sea Dogger Bank. This project is aimed at achieving a better understanding of the dynamics of the circulation processes of the seas around the UK, in order to characterise the extent and nature of density driven and seasonal jet-like circulation which acts as a direct and rapid pathway for transport of material. This project was conducted by the Centre for Environment, Fisheries and Aquaculture Science (CEFAS), Lowestoft Laboratory, led by Dr. Stephen Dye. The CTD data have been received by BODC as raw files from the RV Endeavour, processed and quality controlled using in-house BODC procedures and are available online to download from the BODC website.

  • This dataset comprises hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during April 1991. It incorporates CTD sections and anchor stations in the Humber Estuary, Humber Plume and the Wash plus a CTD section E-W across the North Sea along 53N. The data were collected by the Ministry of Agriculture, Fisheries and Food Lowestoft Fisheries Laboratory as part of the Joint Nutrient Study I (JoNuS).

  • This dataset comprises hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during January 1994. It incorporates CTD profiles on a station at 53.25N, 0.75E off the mouth of the Wash. The data were collected by the Ministry of Agriculture, Fisheries and Food Lowestoft Fisheries Laboratory.

  • This dataset comprises hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during January 1993. It incorporates a CTD survey of the waters within 20 miles of the UK east coast from the Tees to the Thames including stations in the Humber Estuary, Humber Plume and the Wash. The data were collected by the Ministry of Agriculture, Fisheries and Food Lowestoft Fisheries Laboratory as part of the Joint Nutrient Study I (JoNuS).

  • This dataset comprises hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during May 1994 in the Irish Sea. The data were collected by the Ministry of Agriculture, Fisheries and Food Lowestoft Fisheries Laboratory.

  • This dataset comprises hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during October - November 1990. It incorporates CTD sections and anchor stations in the Humber Estuary, the Wash and the coastal waters from the Tyne to 55 30N. The data were collected by the Ministry of Agriculture, Fisheries and Food Lowestoft Fisheries Laboratory as part of the Joint Nutrient Study I (JoNuS).

  • This dataset comprises 48 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during November - December 1993 from stations on the shelf off Tagos and Sado between 38 - 39 N, 8 - 10 W. 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 Instituto Hidrografico, Portugal as part of the Ocean Margin Exchange (OMEX) I project.

  • The dataset comprises 16 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Irish Sea and St. George's Channel area specifically the NW Irish Sea and Bristol Channel, during April of 1996. 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 Ministry of Agriculture, Fisheries and Food Lowestoft Fisheries Laboratory.

  • The dataset comprises 19 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North Sea area specifically the north east coast of England, between the Firth of Forth and Flamborough Head, and in the vicinity of the Dogger Bank. The data were collected during July of 1997. 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 Centre for Environment, Fisheries and Aquaculture Science Lowestoft Laboratory.
