DESCRIPTION:Environmental Biology Seminar Series. Invited speaker: Professo
 r Jackie Goordial\, University of Guelph\; this seminar is hosted by the W
 hyte Lab\n\nOnline seminar from 11:30-12:30 EST\n\nOnline discussion from 
 2-3:00 EST\n\nMuch of what we know about the marine deep biosphere is from
  efforts on microbial life in deep sediments\, which has revealed life to 
 be extensive\, diverse\, and capable of maintaining slow metabolic activit
 y on very long timescales. Comparatively less is known about the microbial
  life hosted within oceanic crust\, primarily because the low amounts of b
 iomass results in difficult or impossible to obtain DNA for genomic analys
 is to determine identity and function of the rock inhabiting communities. 
 In spite of generally low biomass in oceanic crust\, given the sheer volum
 e of this habitat\, the marine rock subsurface is potentially one of Earth
 ’s largest biospheres\, and crustal microbiota have profound impacts on gl
 obal biogeochemical cycling. The Atlantis Massif is an underwater mountain
  near the Mid-Atlantic Ridge (30°N) where ultramafic and mafic rock sequen
 ces have been uplifted to the seafloor along a fault zone.  IODP Expeditio
 n 357 used seabed drills for the first time in the ocean drilling program 
 to collect shallow subsurface cores from this environment\, recovering sed
 iment and rock samples with ultralow biomass (10 - 10\,000 cells cm-3). In
  this talk\, I will discuss novel genomic insights into microbial lifestyl
 es in oceanic crust\, enabled by sorted cell concentration methodologies a
 nd novel fluorescent staining techniques.\n\nTo obtain the Zoom link to pa
