Presentation Transcript

  1. Ocean Acidification Impacts on Sea-Surface Biology, Biogeochemistry and Climate • NERC Consortium grant led by University of Southampton and involving MBA, NHM, NOC, PML, SAHFOS, SAMS, UEA and Universities of Essex and Oxford. • Goal of project is to investigate links between changes in ocean carbonate system (acidification) and plankton biodiversity and community structure, organism physiology and morphology, biogeochemical rates, food webs and climate-relevant processes. • Three cruises: UK (2011), Arctic (2012), Antarctic 2012/13. • Cruises involve: • In situ observations/measurements (water/net sampling and analysis). • On-deck bioassay experiments examining response of in situ community to elevated CO2. Water collection, incubation and analysis – 5 day turnaround so 5 or 6 experimental stations. • Access to Norwegian, Greenland and Iceland waters, including ice-covered waters (but no on-ice work)
