  • This dataset collection comprises solid and liquid coastal freshwater fluxes from land ice in Greenland, Canadian Arctic Archipelago, Svalbard and Iceland. Tundra runoff from all these land areas is also included. The fluxes have been routed to coastal grid cells around the margins of the land areas. The fluxes are provided in three fields: tundra, surface runoff over ice, solid ice discharge (icebergs, for Greenland only). The data are on a 5 km polar stereographic projection with a monthly time step and are in a netcdf format. Detailed description of the derivation of the data can be found in an associated paper in JGR-Oceans: Bamber J.L, et al "Land ice freshwater budget of the Arctic and North Atlantic Oceans. Part I: Data, methods and results". This dataset contains monthly resolution runoff and annual resolution discharge (at monthly time steps) from 01/01/1958 to 31/12/2016.

  • The oceanographic part of the ACSIS (North Atlantic Climate System Integrated Study) project uses sustained observations from the North Atlantic, gathered during other observational programs, such as RAPID, Argo and OSNAP, to generate ocean heat budgets. The overarching objective of the ACSIS project is to enhance the UK’s capability to detect, attribute and predict changes in the North Atlantic Climate System, comprising: the North Atlantic Ocean, the atmosphere above it including its composition, and interactions with Arctic Sea Ice and the Greenland Ice Sheet. The data will be combined with models to develop new products. ACSIS is delivered by a partnership between six NERC Centres, National Centre for Atmospheric Science (NCAS), National Oceangraphy Centre (NOC), British Antarctic Survey (BAS), National Centre for Earth Observation (NCEO), Centre for Polar Observation and Modelling (CPOM), Plymouth Marine Laboratory (PML) and the UK Met Office. ACSIS has been fully funded for five years (2016-2021) through the Natural Environment Research Council (NERC) Long Term Science commissioning, which aims to encourage its research centres to work closely together to tackle major scientific and societal challenges. The oceanographic data are held by the British Oceanographic Data Centre (BODC), the atmospheric, cryospheric and model data are held by the Centre for Environmental Data Analysis (CEDA).

  • This dataset comprises metocean (current, wave,wind, meteorology and water level) data collected by oil companies Shell, BP and Total at their offshore oil and gas fields worldwide. It does not included the hindcast modelling simulations which were run on behalf of these oil companies; just the metocean measurements. Additionally, some data on the effect of water motion on platform stability, corrosion (dissolved oxygen concentration), ice thickness and movement and hydrography (vertical profiles of salinity, temperature and density and occasionally sound velocity) are included. The vast majority of the data were measured by instruments, although some human observations of wind speed and wave height and direction are also included. Geographic coverage is worldwide, according to the location of offshore oil and gas fields: NE and NW Atlantic, North Sea, Norwegian Sea, Mediterranean Sea, Adriatic Sea, Caspian Sea, Red Sea, Gulf of Aden, Gulf of Oman, Persian Gulf, Gulf of Mexico, Gulf of Guinea, South Atlantic, Magellan Straits, Sea of Okhotsk, Indian Ocean, South China Sea, Seram Sea, Malacca Straits, Makassar Strait. The earliest dataset was collected in 1961 and the most recent in 2010. Collection is ongoing. At present, there are over 2550 datsets covering more than 2000 years of observations of winds, waves, currents and sealevels.
