ACCACIA hydrographic, biogeochemical and meteorological data from cruises in the Arctic Ocean (March and July 2013) as part of the Arctic Research Programme

This dataset consists of a hydrographic, biogeochemical and meteorological data. Hydrographic profiles, underway measurements and point sources provided information on the water column structure including temperature, salinity and fluorescence. The biogeochemical water sampling programme provided details on nutrients. Meteorological parameters were measured across the study area. Data collection was undertaken in the Arctic Sea. The data were collected during the period 15 - 31 March 2013 during RV Lance ACCACIA cruise and from 13 July - 16 August 2013 during RRS James Clark Ross JR20130713 (JR288) cruise. Measurements were taken using a variety of instrumentation, including conductivity-temperature-depth (CTD) profilers with attached auxiliary sensors, water bottle samplers, fluorometers, grabs and ship flow-through and meteorological packages. The data have been collected as part of the United Kingdom (UK) Natural Environment Research Council (NERC) Arctic Research Programme (ACCACIA project) to provide information on how aerosol concentration levels change with the seasons and the extent of sea-ice cover. This will help improve modelling of the global climate system and predictions for future climatic change, as well as immediate weather forecasts for mid-to-high latitude locations. Both cruises were undertaken by the University of York- Department Of Chemistry in collaboration with the University of Manchester, University of Leeds, University of Oxford, Plymouth Marine Laboratory, University of Essex, Bangor University and British Antarctic Survey. The Principal Scientist during the first research cruise was James Lee (University of York) and on the second cruise Lucy Carpenter and Rosie Chance, also from the University of York. The Principal Investigator for this project is Ian Brooks (University of Leeds). CTD data, temperature logger data, nutrient data, ship underway monitoring system data and trace gases concentrations in the water and air are held at the British Oceanographic Data Centre. Other data have not yet been supplied or have been supplied to the British Atmospheric Data Centre.
