Scott Doney (2004), Victoria Fabry (2009), Gretchen Hofmann (2009), and Joanie Kleypas (2008) are part of a new committee that will recommend a national plan to research, monitor, and assess ocean acidification. The four Leopold Leadership Fellows were named by the National Research Council in April to the committee, which will recommend priorities for research that will increase understanding of how ocean acidification takes place and reduce uncertainty in projections on the rate of change and the effects on ocean ecosystems.
