Photo by @jtkerby || The cold waters of Alexandra Fiord and the snout of the Twin Glacier pin the valley’s meadows between two dolomitic ridgelines. Research scientist Dr. Isla Myers-Smith (University of Edinburgh) ascends the ridge in front of the glacier, the human scale in this austere yet beautiful landscape. Just decades ago, glacial ice would have covered the spot where Isla stands. As the ice retreats, vegetation and even animal remains are sometimes released from their frozen tombs, hundreds or even thousands of years after being locked away. While this disappearing ice is linked to global climate change, the specimens that emerge from the ice are invaluable to researchers. They act as windows (and even sources of DNA!) into the long past, cold deaths that gave an unexpected gift to science. Fortunately, researchers have been intensively studying this polar oasis for almost 40 years, making it one of the better understood patches of tundra in the Arctic and also a place where inconspicuous data like these are more likely to be spotted. #AlexandraFiord #Ellesmere #HighArctic #Canada || Follow me @jtkerby for more on science and nature in harsh environments.
