Less than 500 miles from the North Pole, the Milne Fiord Epishelf Lake is a unique freshwater lake that floats atop the Arctic Ocean, held in place only by a coating of ice. The lake is dominated by single-celled organisms, notably cyanobacteria, that are frequently infected by unusual "giant viruses." Investigators from Université Laval, Québec, Canada have produced the first assessment of the abundance of the viruses in this lake. The research is published in Applied and Environmental Microbiology.
