Our research interests:

Adaptations of marine microorganisms (from Bacteria, Archaea and their viruses to sea-ice algae (See Krembs et al, 2011 ) to life within physical support structures (frost flowers [See Bowman and Deming, 2010] shown above on the right, sea ice, particle aggregates and sediments), especially as they influence carbon and other elemental cycles. See a recent interview on Quirks and Quarks, CBC radio (scroll to “Algae Architects”).

Cold adaptation in marine microorganisms and relevance to polar geochemistry and ecology (International Northwater Polynya Study, NOW; Canadian Arctic Shelf Exchange Study, CASES; Nansen Amundsen Basins Observational System, NABOS; Canadian Flaw Lead System Study, CFL)

Limits of microbial life, especially in ice, as they relate to astrobiology (UW Astrobiology Program), biotechnology (see genomic information for our model psychrophile at TGIR web site) and bioremediation (UW Marine Bioremediation Program). See some of our most recent work at the UW School of Oceanography’s “Life in Extreme Environs” link at the School’s Interdisciplinary Studies/Research page.

Role of benthic bacteria in biogeochemical cycles and ecosystems, from coastal to deep-sea environments (DGoMB)

Hydrostatic pressure in the evolution and ecology of marine bacteria, especially at very cold (in deep-sea and polar environments) and hot (at hydrothermal vents) temperatures

Some of Jody’s Recent Highlights:

  • See the NSF Highlight on our Arctic frost flower project that involves work by Jeff Bowman and Marcela Ewert.
  • Participated in a March 2012 Campaign in Daneborg, NE Greenland, led by Soeren Rysgaard to examine carbon fluxes through winter sea ice. See the video of this effort.
  • Read blogs on exopolymers in sea ice at DeepBlueHome and MotherJones.
  • Read a recent interview with Jody at Action Bioscience.org.
  • Chief Scientist for Leg 5B of the overwintering icebreaker expedition in the Arctic for CFL, the Circumpolar Flaw Lead Systems Study, Canada’s flagship International Polar Year (IPY) 2007-2009 project (Listen to the CBC radio broadcast from CFL)
  • Participant in the ArcticNet 2006 expedition through the Northwest Passage. See the Washington Post article. A short video also summarizes the 2006 effort.
  • Recipient of an honorary doctorate from Université Laval, Quebec City, June 2006.
  • Instructor for the 2005 IARC International Summer School on Climate Change in the Arctic Ocean via NABOS
  • Participant in the NOAA-Ocean Exploration collaborative research effort (go to the link
    for ‘Arctic Exploration’)
  • Served as Chief Scientist for the 2003-2004 overwintering expedition of the Canadian Arctic Shelf Exchange Study (CASES)
  • Chaired the International Polynya Symposium 2001 in Quebec City in September
