from Wikipedia, the free encyclopedia

Sallie "Penny" Watson Chisholm (born November 5, 1947 in Marquette ) is an American oceanographer and marine biologist.

Chisholm graduated from Skidmore College with a bachelor's degree in 1969 and received a PhD in biology from the State University of New York at Albany in 1974 . She was a postdoctoral fellow at the Scripps Institute of Oceanography in San Diego until 1976 . From 1976 she was a professor at the Massachusetts Institute of Technology (MIT) and regularly at the Woods Hole Marine Research Laboratory, whose program in oceanography she headed from 1988 to 1995. From 1993 she was professor of biology at MIT and from 2002 Professor of Environmental Studies (Lee and Geraldine Martin Professor of Environmental Studies). She is in both the Faculty of Civil and Environmental Engineering and the Faculty of Biology. In 2002 she became co-director of Terrascope and the Earth System Initiative.

Chisholm studied the diet and life cycles of phytoplankton in the sea and found in the late 1980s that cyanobacteria (especially Prochlorococcus marinus ) play a significantly greater role in photosynthesis (and in other global cycles) than previously assumed. She has also emerged as a critic of proposals for iron fertilization to counteract the decline in plankton due to global warming.

In 2010 she received the Alexander Agassiz Medal , 1991 the Rosenstiel Award in Oceanography, 2012 the Ruth Patrick Award of the Association for the Sciences of Limnology and Oceanography, 2013 the Ramon Margalef Prize and 2011 the National Medal of Science . For 2019, Chisholm was awarded the Crafoord Prize . She is a member of the National Academy of Sciences , the American Academy of Arts and Sciences (since 1992) and the American Association for the Advancement of Science . In 1997/98 she was a Guggenheim Fellow .

She wrote two popular science children's books about her work.
