Environmental Microbiology in the High Arctic

1 Comment

Swimming in icy cold fjords, Summer barbecues at 4C, insomnia under the midnight sun, polar bears roaming about… I was in no doubt that I was somewhere like nowhere else on Earth. If I was even on Earth at all. The University Centre in Svalbard (UNIS) is the world’s northernmost institution of higher education, located at 78º N in Longyearbyen, Norway. There, I fell in love with the amazing landscape and the diversity of life! The fauna and flora of Svalbard includes more than 1,800 marine invertebrate species, 1,200 terrestrial or freshwater invertebrate species and over 170 higher plant species in addition to the 21 mammal and 28 bird species.

While it is a stunning environment, the high Arctic is is harsh, and the challenges microbiologists face in the high Arctic were due to low biomass, unknown target, unknown selection pressures, the remote fieldwork, low activity of microbes, contamination, and typically only getting one initial sample.

  1. Awesome post Kristine – what is a cryconite? And what did you learn about polar viruses? I can’t wait to hear more at next week’s lab mtg!
