    Blanchette, Robert A.; Held, Benjamin W.; Arenz, Brett E.; Jurgens, Joel Allan; Baltes, Nicolas; Duncan, Shona Margaret; Farrell, Roberta L. (Springer Science Bus Media BV, 2010)
    The historic expedition huts located in the Ross Sea Region of the Antarctic and the thousands of artifacts left behind by the early explorers represent important cultural heritage from the “Heroic Era” of Polar exploration. ...
  • Environmental pollutants from the Scott and Shackleton expeditions during the ‘Heroic Age’ of Antarctic exploration

    Blanchette, Robert A.; Held, Benjamin W.; Jurgens, Joel Allan; Aislabie, Jackie M.; Duncan, Shona Margaret; Farrell, Roberta L. (Cambridge University Press, 2004)
    Early explorers to Antarctica built wooden huts and brought huge quantities of supplies and equipment to support their geographical and scientific studies for several years. When the expeditions ended and relief ships ...
  • Functional ecology of an Antarctic Dry Valley

    Chan, Yuki; Van Nostrand, Joy D.; Zhou, Jizhong; Pointing, Stephen B.; Farrell, Roberta L. (National Academy of Sciences, 2013)
    The McMurdo Dry Valleys are the largest ice-free region in Antarctica and are critically at risk from climate change. The terrestrial landscape is dominated by oligotrophic mineral soils and extensive exposed rocky surfaces ...
  • Hexadecane mineralization activity in hydrocarbon-contaminated soils of Ross Sea region Antarctica may require nutrients and inoculation

    Aislabie, Jackie M.; Ryburn, Janine; Gutierrez-Zamora, Maria-Luisa; Rhodes, Phillipa; Hunter, David; Sarmah, Ajit K.; Barker, Gary M.; Farrell, Roberta L. (Elsevier, 2012-02)
    Hydrocarbon spills on Antarctic soils occur mainly near settlements where fuel is stored and aircraft and vehicles are refuelled. To investigate those factors that may preclude hexadecane mineralization activity in long-term ...
  • Highly specialized microbial diversity in hyper-arid polar desert

    Pointing, Stephen B.; Chan, Yuki; Lacap, Donnabella C.; Lau, Maggie C.Y.; Jurgens, Joel Allan; Farrell, Roberta L. (2009-11-24)
    The McMurdo Dry Valleys in Antarctica are a cold hyperarid polar desert that present extreme challenges to life. Here, we report a culture-independent survey of multidomain microbial biodiversity in McKelvey Valley, a ...
