East Antarctica’s Totten Ice Shelf is Warming
From Nature: “On a glorious January morning in 2015, the Australian icebreaker RSV Aurora Australis was losing a battle off the coast of East Antarctica. For days, the ship had been trying to push through heavy sea ice… Then the weather came to the rescue, with a wind change that blew the ice away from the shore, opening a path through the pack… Rintoul and his team were the first scientists to reach the Totten Ice Shelf — a vast floating ice ledge that fronts the largest glacier in East Antarctica… The team had to work fast before the ice closed again and blocked any escape. For more than 12 hours, Rintoul and his colleagues carried on non-stop, probing the temperature and salinity of the water, the speed and direction of ocean currents as well as the shape and depth of the ocean floor… These first direct observations confirmed a fear that researchers had long harboured… East Antarctica is well below sea level, which makes it more vulnerable to the warming ocean than previously thought.”

Benthic Colonization in the Antarctic Peninsula
From Ecography: “The Antarctic Peninsula is among the places on Earth that registered major warming in the last 60 years… The loss of sea-bed ice coverage, on the one hand has been affecting benthic assemblages, but on the other it is opening up new areas for benthic colonization. Potter Cove (South Shetland Islands) offered the opportunity of assessing both processes. We recently reported a sudden shift of benthic assemblages related to increased sedimentation rates caused by glacier retreat. This glacier retreat also uncovered a new island that presents a natural experiment to study Antarctic benthic colonization and succession… Under the current scenario of climate change, these results acquire high relevance as they suggest a two-fold effect of the Antarctic Peninsula warming: the environmental shifts that threaten coastal ecosystems, and also the opening up of new areas for colonization that may occur at a previously unimagined speed.
