Education and career

edit

Humphris grew up in the United Kingdom, where she learned to sail and enjoyed hikes that incited her interest in the natural world.[1] As a child, she was not fond of history classes, but enjoyed the other subjects.[2] Humphris has an undergraduate degree from Lancaster University (1972),[3] and earned her Ph.D. in 1976 from the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution.[4] Following her Ph.D., she spent time as a postdoc at Imperial College in London and a year at Lamont–Doherty Earth Observatory.[1] For more than a decade,[when?] Humphris was a staff scientist at Sea Education Association before she joined the staff at Woods Hole Oceanographic Institution in 1992.[1]

In 2013, Humphris was elected a fellow of the American Geophysical Union who cited her "For sustained and exemplary contributions to our understanding of volcanic and hydrothermal processes at mid-oceanic ridges".[5]

Research

edit

Humphris' research started with investigations into high temperature alterations of oceanic basalts.[6][7] She has examined the geochemistry of hydrothermal systems at multiple locations including the Walvis Ridge in the South Atlantic,[8] the mid-ocean ridges near Tristan da Cunha[9] the TAG vent field,[10][11][12] and Lucky Strike.[13] Humphris worked with the team that found evidence of life in ancient rocks in samples drilled from the Earth's mantle.[14][15] She has participated in multiple dives to the seafloor in submersibles including Nadir[16] and Alvin, and was the lead scientist for the 2012 overhaul of the DSV Alvin.[17] In 2018, she summarized scientists' progress in understanding the controls on hydrothermal vent fluid composition in an article published in Annual Review of Marine Science.[18]
