Paytan Receives 2015 Paleoceanography and Paleoclimatology Dansgaard Award
Adina Paytan will receive the inaugural Dansgaard Award at the 2015 American Geophysical Union Fall Meeting, to be held 14–18 December in San Francisco, Calif., as selected by a Dansgaard Award selection committee. The award is given in recognition of the awardee's research impact, innovative interdisciplinary work, educational accomplishments (mentoring), societal impact, and other relevant contributions and to acknowledge that the awardee shows exceptional promise for continued leadership in paleoceanography or paleoclimatology.
Historic Hurricane Data Give a Warning for the Future
Sediment cores from a Massachusetts pond help suggest that as ocean temperatures rise, the occurrence of severe hurricanes along North America's Atlantic coast will increase.
