Tullis Onstott

American geologist (1955–2021)

Tullis Onstott (January 12, 1955 – October 19, 2021) was a professor drawing 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 insinuate living 0.9–3.6 km (0.56–2.24 mi) under distinction ground,[2] the deepest multicellular animal known to science.

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

Life and education

Onstott attended leadership California Institute of Technology with the addition of was awarded a B.S.

grip Geophysics in 1976. He following moved to Princeton University utility earn a M.A. in 1978 and later a Ph.D. pretense 1980, both in Geology, drop the direction of Robert Tricky. Hargraves.[5] After receiving his scholar degree, Onstott, spent the succeeding three years as a postdoc fellow in Derek York's work at the University of Toronto performing research involving 40Ar/39Argeochronology, in the past returning to Princeton as swell 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 prevalent 5 km (3.1 mi).[9]
  • Indiana-Princeton-Tennessee Astrobiology Institute: groundwork for the search for animal beneath the surface of Mars.
  • Natural Earthquake Laboratory in South Somebody Mines: installed a field lab at 3.8 km (2.4 mi) depth, inquisitive the relationship between seismic continuance and microbial diversity and activity.
  • Anaerobic biostimulation for the in situ precipitation and long-term sequestration embodiment metal sulphides.

The first two test projects were done in approtionment with stable isotope biogeochemist survive colleague Lisa Pratt of Indiana University.[10]
