  • The dataset comprises 43 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the English Channel, North Sea, Irish Sea and St. George's Channel, and the Bristol Channel areas, specifically from between Liverpool and the Isle of Man and then at various locations around the west, south west and south coasts up to the east of Ipswich. The data was collected during January and February of 2003. 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.

  • This dataset contains particle flux analyses and current measurements collected from sediment traps and associated moored current meter instrumentation. Four McLane sediment traps were deployed in the Iceland Basin (by the Ocean Weather Station India) in a mesoscale array around 60 degrees N 20 degrees W to sample particle flux time series between November 2006 - July 2007 and August 2007 - June 2008. Sediment traps were deployed with Aanderaa RCM8 current meters 15 m below the traps, recording current speed and direction once an hour. The sediment traps were initially deployed during RRS Discovery cruise D312 and recovered on RRS Discovery cruise D321. For the second deployment period the traps were deployed on RRS Discovery cruise D321 and recovered on RRS Discovery cruise D340. The first sediment traps were prepared for analysis by scientists shortly after recovery. The second deployment samples were stored in the dark at 4 degrees Celsius until 2016 and were subsequently analysed. All sediment trap samples are preserved with formalin and hence should not be affected by long time storage. The samples were analysed for mass flux, particulate organic carbon (POC) and nitrogen (PON) flux, calcium carbonate flux, biogenic silica flux (including dissolved contribution for deployment 2), strontium flux (including Acantharian cyst fractions for deployment 1 and 2 and particulate fractions for deployment 2). The samples from the latter part of deployment 2 are thought to have severely under collected and so those data are flagged. The dataset was produced for the purposes of calculating sediment fluxes in the Iceland Basin and was funded by the Natural Environment Research Council (NERC) - Oceans 2025 Programme (Grant number NE/L002531/1).

  • This dataset contains high and low water values manually digitised from historic hand-written tabulated ledgers, from the Port of London Authority (PLA). The dataset contains 463 years of data, from across 15 tide gauge sites along the Thames Estuary (bounding box = -0.3159W, 51.3914N, 1.3797E, 51.8428N), for the period 1911 to 1995. When these historic records are combined with digital records available from the PLA since 1995, the new sea level time-series spans the 109-year period from 1911 to 2019. London is one of the world’s most important coastal cities and is located around the Thames Estuary. Quantifying changes in sea levels in the Thames Estuary over the 20th century and early part of the 21st century is vital to inform future management of flood risk in London. This dataset is of importance for ongoing monitoring of mean sea-level rise, and changes in tidal range and extreme sea levels in the Thames Estuary. The project was led by the Ocean and Earth Science, University of Southampton and the Environment Agency, with contributions from the Leibniz Institute for Baltic Sea Research Warnemunde and the National Oceanography Centre. The study contributes to the objectives of UK National Environment Research Council (NERC) project E-Rise: Earliest detection of sea-level rise accelerations to inform lead time to upgrade/replace coastal flood defence infrastructure (NE/P009069/1; I.D.H.).

  • The dataset comprises 68 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North East Atlantic Ocean (limit 40W) area specifically the Gt.Meteor Table Mount,Moroccan,Portuguese,Spanish,Amorican shelf during March and April of 1992. 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.

  • Collection of geophysical and oceanographic data from several cruises dedicated to the repeated mapping and monitoring of three UK Marine Protected Areas (MPAs) - Haig Fras, Whittard Canyon and the Darwin Mounds. Data were collected during the following 2018-2020 cruises: JC166/7, DY103, DY108/9, DY120 and DY106. Data collection took place at three of the UK’s MPAs - Haig Fras Marine Conservation Zone (MCZ) in the Celtic Sea, Whittard Canyon submarine complex, which includes The Canyons MCZ, situated off the south west UK continental shelf and Darwin Mounds Special Area of Conservation (SAC), situated in the northern Rockall Trough. An Autonomous Underwater Vehicle (AUV) was used to collect photographic data, sidescan sonar and multibeam bathymetry. Other data included shipboard multibeam bathymetry data; moored ADCP, CTD and sediment trap datasets from repeat mooring deployments; ROV video, pushcores and specimen samples; settling plate experiments; box cores and mega cores; BioCam imagery. The MPAs under investigation had been previously surveyed on cruises JC035 (2009) and JC125 (2015) hence these cruises formed part of the Fixed Point Observations Underpinning Activity. Here repeated observations and surveys of MPAs and their surroundings aim to provide insight into the development and recovery of benthic ecosystems following natural and/or anthropogenic impacts. The data collection was undertaken by scientists at the UK’s National Oceanography Centre (NOC) and formed part of the Natural Environment Research Council (NERC) Climate Linked Atlantic Sector Science (CLASS) Programme (NERC grant reference NE/R015953/1).

  • The dataset comprises 12 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North Atlantic Ocean area specifically just north of the Equator in the central Atlantic, during July and August of 1974. 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 Institute of Oceanographic Sciences Wormley Laboratory.

  • The WireWall project developed a prototype wave overtopping field measurement system. The system was designed and trailed at Crosby Beach, Hall Road carpark, north of Liverpool during winter 2018/2019. The data collected include both wave-by-wave overtopping volumes and horizontal velocities. At the time of the project the coastal structure at this site comprised a stepped revetment and vertical sea wall with a recurve. The system was designed at the National Oceanography Centre, validated in HR Wallingford’s flume facility and deployed with Sefton Council. Five datasets are available from the project. These contain processed data from: 1) The numerical wave overtopping estimates for past events used to design the system and plan deployments; 2) The numerical wave overtopping estimates for the joint wave and water level conditions with a 1 in 1 year return period probability to a 1 in 200 year return period probability in Liverpool Bay; 3) The dock side tests; 4) The physical laboratory experiments; and, 5) The field trials during windy spring tides. For Crosby these data can be used to validate/calibrate numerical tools used for coastal scheme design and flood hazard forecasting. Beach profile data collected alongside the overtopping measurements have been archived with the Northwest Regional Coastal Monitoring Programme, https://www.channelcoast.org/northwest/. This project was delivered by the National Oceanography Centre in collaboration with HR Wallingford. Our project partners were Sefton Council, Balfour Beatty, Environment Agency, Channel Coastal Observatory and Marlan Maritime Technologies.

  • The Impacts of Deglaciation on Benthic Marine Ecosystems in Antarctica (ICEBERGS) dataset comprises of physical oceanography, marine geology, habitat mapping, community structure and seabed sediment data. The data were collected from CTD deployments, multi-beam swath bathymetry surveys, TOPAS sub-bottom profiling, shallow underwater camera system deployments, plankton net deployments, Agassiz trawls, Hamon grabs and multi-corer deployments during three seasonal cruises around the West Antarctic Peninsula beginning 2017 and scheduled to end in 2021. The data were collected as part of the ICEBERGS project to investigate the impacts of physical disturbance arising from climate-warming induced deglaciation on benthic communities around the West Antarctic Peninsula. The ICEBERGS project is part of the joint funded NERC-CONICYT Initiative and involves collaboration between the University of Exeter, University of Bangor, British Antarctic Survey (BAS) and Universidad Católica de la Santísima Concepción. The physical data will be managed by the British Oceanographic Data Centre (BODC) with the remainder of the data being submitted to the Polar Data Centre (BAS-PDC).

  • The dataset comprises the combination of estimates of anthropogenic carbon derived from hydrographic occupations of the 26N section with volume transports for the area between east USA and Africa calculated using the RAPID-MOCHA-WBTS AMOC timeseries. The data cover the time period between April 2004 and October 2012. The observations will be used with data from other sources to determine and interpret the accumulation of anthropogenic carbon in the North Atlantic, to infer the magnitude and variability of uptake of anthropogenic carbon dioxide from the atmosphere, and assess the risk of changes in the meridional overturning circulation on the marine carbon cycle. The Atlantic Biogeochemical Fluxes programme (ABC-Fluxes) is a joint effort between NERC in the UK (Principal Investigator Elaine McDonagh), and NOAA in the USA (Molly Baringer). It builds on the work of the RAPID-MOCHA-WBTS programme, a joint effort between NERC in the UK (Principal Investigator Eleanor Frajka-Williams), NOAA (Molly Baringer) and RSMAS (Bill Johns) in the USA. The Atlantic anthropogenic carbon transport (and its components), calculated from the above data, are held by BODC in NetCDF format.

  • A dataset collected by investigators of the University of East Anglia during January - February 2020 in the tropical North Atlantic. Gliders SG620 and SG637 were deployed from the RV Meteor during cruise M161 as part of the EUREC4A oberservational campaign. Glider SG579 was deployed by the autonomous surface vehicle Caravela. All gliders were recovered by the Meteor. SG620 and SG637 occupied a bowtie pattern 10 km across centered at 14'10''N 57'20''W. The two gliders were deployed with CT sails measuring conductivity and temperature and completed 131 and 155 dives respectively. SG579 was deployed at 13'21''N 58'50''W and travelled 200 km to the bowtie over 10 days conducting 75 dives. Once onsite, SG579 conducted a further 220 dives. In addition to a CT sail, SG579 carried a PAR sensor and Wetlabs sensor measuring backscatter, chlorophyll a and CDOM. Data were processed using the UEA Seaglider Toolbox.
