Graham Michael "Mike" Purdy is a British geophysicist and oceanographer who specializes in marine seismology.
In 1991, he became Chairman of the Department of Geology and Geophysics (G&G), a position he held until leaving WHOI in 1995 for the NSF.
He oversaw a breadth of research activities, including the international Ocean Drilling Program and the foundation-wide Life in Extreme Environments (LExEn) initiative, which he established in 1997 [1].
LDEO is the largest component of this alliance, and Purdy has taken an interest in interdisciplinary approaches to the traditional earth science work of the department.
He has dedicated particular attention to the problem of climate change, particularly as highlighted by the work of fellow LDEO scientist Wally Broecker.
