The fieldwork element of the project aimed to generate datasets consisting 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. No data have been received by BODC for this project.
