  • This dataset consists of underwater benthic imagery and measurements of light attenuation taken from Paluma Shoals in the Coral Sea following a 2016 El Niño coral bleaching event. Data were collected between 09 and 11 August 2016. Benthic imagery was captured using a SeaViewer Sea-Drop™ Camera (950 Analog model) on 10 August 2016. Light attenuation measurements were taken using a LiCOR LI-192SA Light Meter deployed at a range of depths below the sea surface. These cruises formed the field component of NERC Discovery Science project "Quantifying ENSO-related bleaching on nearshore, turbid-zone coral reefs grant story”. The data were collected following a major El Niño event which caused mass coral bleaching across the Great Barrier Reef. The event provided opportunity to undertake a rapid assessment of the impacts of bleaching on the turbid-zone reefs in the vicinity of Paluma Shoals (central Halifax Bay). The aim of the project is to ascertain: 1) The total extent of bleaching-induced mortality; 2) The extent to which specific coral species have been impacted; 3) Any immediate impacts on the structural complexity and diversity of the reefs. The Discovery Science project was composed of Standard Grant NE/P007694/1. The grant was held by the University of Exeter, School of Geography and led by Professor Christopher Perry. The funding period ran from 01 July 2016 to 31 March 2017. All data described have been received by BODC from the RRS James Clark Ross and will be processed and made available online in the future. Raw data are available on request. No further data are expected from this project.

  • This dataset comprises 30 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in August 1989 from stations covering the southern North Sea in a area off Flamborough Head. 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 Wales, Bangor School of Ocean Sciences as part of the North Sea Project Frontal Process Study

  • The 'End of the Pier' Menai Strait data set is a collection of biogeochemical and physical parameters (including temperature, salinity, transmittance and attenuation of the water column) measured in the Menai Strait since 1955.The aim is to concatenate data both historical and current, preventing the loss of valuable information and creating a time series for a variety of parameters in a unique environment. Data have been extracted from Ph.D. and M.Sc. theses undertaken at the School of Ocean Sciences (SOS) at Bangor University, in addition to published sources. In all cases data has undergone a very thorough quality audit and sufficient detail is provided so that the original source may be located. Data collection is ongoing but the British Oceanographic Data Centre (BODC) only holds data up to 2003.

  • 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).

  • The dataset comprises 136 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North East Atlantic Ocean (limit 40W) and the Inner Seas off the West Coast of Scotland areas specifically all across the West of Scotland during July of 1983. 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 Wales, Bangor School of Ocean Sciences.

  • This dataset comprises hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during April 1994. It incorporates CTD profiles from 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 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.

  • The dataset comprises 44 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North Sea area specifically Wee Bankie/Marr Bank during the month of May 2005. 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 Fisheries Research Services Aberdeen Marine 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 89 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, in September 1988 from stations covering the Flamborough Head frontal system. 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 Wales, Bangor School of Ocean Sciences as part of the North Sea Project Frontal Process Study.
