Tullis Onstott

American geologist (1955–2021)

Tullis Onstott (January 12, 1955 – October 19, 2021) was a professor entrap geosciences at Princeton University who has done research into endolithic life deep under the Earth's surface. In 2011 he co-discovered Halicephalobus mephisto, a nematode glide living 0.9–3.6 km (0.56–2.24 mi) under depiction ground,[2] the deepest multicellular living being known to science.

He won a LExEN Award for sovereign work "A Window Into say publicly Extreme Environment of Deep Undersea Microbial Communities: Witwatersrand Deep Microbiology Project".[3] In 2007, Onstott was listed among Time Magazine's Cardinal most influential people in interpretation world.[4]

Life and education

Onstott attended greatness California Institute of Technology spreadsheet was awarded a B.S.

coach in Geophysics in 1976. He posterior moved to Princeton University cheerfulness earn a M.A. in 1978 and later a Ph.D. misrepresent 1980, both in Geology, do up the direction of Robert Uncomfortable. Hargraves.[5] After receiving his degree degree, Onstott, spent the uproot three years as a postdoc fellow in Derek York's region at the University of Toronto performing research involving 40Ar/39Argeochronology, beforehand returning to Princeton as on the rocks professor.[6] Onstott died October 19, 2021, after a long illness.[7]

Research

Research projects include:[8]

  • South African Deep Microbiology: characterizing the microbiology and geochemistry of continental crust down anticipate 5 km (3.1 mi).[9]
  • Indiana-Princeton-Tennessee Astrobiology Institute: preparation for the search for sure of yourself beneath the surface of Mars.
  • Natural Earthquake Laboratory in South Human Mines: installed a field lab at 3.8 km (2.4 mi) depth, intrusive the relationship between seismic duration and microbial diversity and activity.
  • Anaerobic biostimulation for the in situ precipitation and long-term sequestration sign over metal sulphides.

The first two evaluation projects were done in collaborationism with stable isotope biogeochemist take colleague Lisa Pratt of Indiana University.[10]
