Characterisation of bacterioplankton communities in the meltwater ponds of Bratina Island, Victoria Land, Antarctica
A unique collection of Antarctic aquatic environments (meltwater ponds) lies in close proximity on the rock and sediment-covered undulating surface of the McMurdo Ice Shelf, near Bratina Island (Victoria Land, Antarctica). During the 2009–10 mid-austral summer, sets of discrete water samples were co...
