The COMICS (Controls over Ocean Mesopelagic Interior Carbon Storage) project consists of observations, at sea, of particle flux and stable isotopes. It applies organic geochemical and molecular biological techniques to samples collected using nets and traps. The study areas are the tropical Atlantic and Southern Oceans. The results will be combined with models to quantify the flow of carbon in the ocean’s ‘twilight’ zone in order to accurately model global climate change. This ‘twilight’ zone is the part of the ocean between 100m and 1000m below the sea surface, where only a small amount of light from the sun can still penetrate. By investigating carbon dynamics in the ocean interior, COMICS will help to improve predictions of future global climate change. The COMICS project is led by the National Oceanography Centre and is a collaboration between the British Antarctic Survey and the universities of Queen Mary London, Liverpool, Oxford and Southampton. The project received funding from the Natural Environmental Research Council and runs between 2017 and 2022.
This dataset consists of measurements of wave height, direction and frequency, bubble size distribution, Autoflux measurements of air-sea fluxes CO2, and WAVEX measurements of directional wave radar. Data were collected onboard the RRS James Clark Ross in the Weddell Sea during cruises in the 2010/2011, 2011/12 and 2012/13 field seasons. Meteorology data were collected using an aspirated psychrometer and temperature and humidity sensors mounted above the bridge of the ship. Wavex and Autoflux systems were run for the duration of each cruise. Bubble size distributions were measured with two acoustic resonators. These cruises formed the field component of NERC Discovery Science project "Waves, Aerosol and Gas Exchange Study (WAGES)”. The data were collected to measure the amount of aerosol at different sizes generated near the surface and transported upwards into the atmosphere, along with the wind speed, wave size and white-capping under a wide range of different conditions. The aim was to improve understanding of aerosol generation and ultimately the way in which clouds are represented within climate models. The Discovery Science project was composed of three Standard Grants. The lead grant, NE/G00353X/1, was held by the University of Leeds, School of Earth and Environment, with Professor Ian M. Brooks as principal investigator. The funding period for this grant was 01 August 2009 to 31 March 2014. Child grant NE/G003696/1 was held by the National Oceanography Centre, Department of Science and Technology and was led by Professor Meric Srokosz. The funding period for this grant was 01 September 2009 to 31 March 2014. The third grant was held under the title “pCO2 data collection on James Clark Ross in support of Autoflux” at the Plymouth Marine Laboratory. It was led by Professor Phillip D. Nightingale and was funded for the period covering 01 April 2010 to 31 March 2013. 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.
This dataset comprises 45 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during December 1998 - January 1999 from stations off the coast of Vigo and in the Nazare Canyon. 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 Rostock Institute of Biosciences as part of the Ocean Margin Exchange (OMEX) II project.
This dataset comprises 41 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, during April - May 1993 from stations in the English Channel, Bay of Biscay, Ria de Vigo, Ria de Arosa and Ria de Muros. 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 Université Libre de Bruxelles, Laboratory of Chemical Oceanography and Water Geochemistry as part of the Ocean Margin Exchange (OMEX) I project.
The Changing Arctic Ocean (CAO) oceanographic dataset comprises data collected in the Arctic Ocean, including the Barents Sea and Fram Strait, as part of the Changing Arctic Ocean programme. The data were collected over multiple research cruises starting in June 2017. The majority of these cruises were conducted during the Arctic summer on board the RRS James Clark Ross, with further winter cruises completed in collaboration with the Nansen Legacy project on board the RV Helmer Hanssen. Shipboard data collection included the deployment of conductivity-temperature-depth (CTD) packages, ocean seagliders, mulitcorers, grabs, nets, trawls, and a shelf underwater camera system. The CAO programme aims to understand the changes in Arctic marine ecosystem in a quantifiable way, enabling computer models to help predict the consequences of these changes on, for example; surface ocean productivity; species distributions; food webs; and ecosystems, and the services they provide (ecosystem services). It was initially a Natural Environment Research Council (NERC) funded programme comprising four projects: Arctic PRIZE (Arctic productivity in the seasonal ice zone), led by Finlo Cottier (Scottish Association for Marine Science - SAMS); ARISE (Can we detect changes in Arctic ecosystems?), led by Claire Mahaffey (University of Liverpool); ChAOS (The Changing Arctic Ocean Seafloor), led by Christian Maerz (University of Leeds) and DIAPOD (Mechanistic understanding of the role of diatoms in the success of the Arctic Calanus complex and implications for a warmer Arctic), led by David Pond (University of Stirling). Additional projects were added to the programme in July 2018 through funding provided by NERC and the German Federal Ministry of Education and Research (BMBF). The majority of data are held by the British Oceanographic Data Centre (BODC) but a proportion of the data, primarily biological, are stored at the British Antarctic Survey Polar Data Centre (email@example.com) and any BMBF funded data are held by Pangaea (https://www.pangaea.de/).
