Cruise Report RRS James Clark Ross JR252 & JR254C, 19 March - 6 April 2011

This cruise report describes the combined JR252 and JR254C cruise on RRS James Clark Ross, departing Port Stanley on March 19th and arriving in Punta Arenas on April 6th. JR252 was the BAS Long-Term Monitoring and Survey (LTMS) cruise to service the mooring array in Orkney Passage, operated jointly between BAS and Lamont-Doherty Earth Observatory (LDEO), Columbia University. In addition, we serviced two of LDEO's moorings in the northern Weddell Sea. JR254C was part of the Waves, Aerosol and Gas Exchange Study (WAGES), aiming to improve our understanding of air-sea fluxes of CO2 and heat and how they are influenced by breaking waves and other factors. The project is based at the National Oceanography Centre, Southampton (NOCS), and the University of Leeds.
