Beached iceberg alters Antarctic marine communities

Studying the effects of expanding sea ice around Antarctica has been challenging, however, as it is difficult to predict exactly where sea ice will expand and whether it will stick around long enough to make a difference on marine life. But a rare event involving an iceberg bigger than the island of Manhattan created just the environment that Graeme Clark, an ecologist at the University of New South Wales in Australia, and his colleagues needed to study how the sudden advent of long-term sea-ice cover affects marine communities.

Ice (Re) Cap

From Antarctica to the Arctic; from polar caps, permafrost and glaciers to ocean-rafted sea ice; and from burly bears to cold-loving microbes, fascinating science is found in every nook and crevasse of Earth’s cryosphere, and new findings are announced often. Here are a few of the latest updates.

    Protecting the mineral treasures of Antarctica's Larsemann Hills

    In 2003, scientists visited the Stornes Peninsula in Antarctica's Larsemann Hills to study the rocks — especially boron and phosphorus minerals. What they found set them on a decade-long path to protect the geology, culminating in 2014 with the naming of the site as an Antarctic Specially Protected Area.

    The amazing minerals of the Larsemann Hills

    Four minerals were discovered on Stornes Peninsula in the Larsemann Hills of East Antarctica based on fieldwork there from 2003 to 2004. In part because of these minerals and other rare boron and phosphate minerals found in this pristine region, Stornes Peninsula is now protected as an Antarctic Specially Protected Area — the highest level of environmental protection in Antarctica. Below are some details about these special minerals.

    Past penguin populations not dependent on ice extent

    Penguins’ lives revolve around ice, so it seems they might be particularly vulnerable to changing ice conditions and ice loss. But a new study charting the rise and fall of penguin populations over the last 30,000 years suggests that past populations have actually increased during times of climate warming and retreating ice.

    Recovery of 1960s sea-ice satellite images wins dark data contest

    Scientists from the National Snow and Ice Data Center (NSIDC) and NASA who resurrected 50-year-old satellite images of Arctic and Antarctic sea ice from dusty 35-millimeter film reels took home first prize in an international geoscience data rescue contest sponsored by publisher Elsevier and the Integrated Earth Data Applications project at Columbia University’s Lamont-Doherty Earth Observatory.

    Travels in Geology: Antarctica: Following in the footsteps of giants

    In fall 2012, when I told friends and colleagues that I was heading south for a few weeks, they assumed that I, like many other northeasterners, was going to Florida or the Bahamas for a break from winter weather. Instead, I was headed to the iciest and southernmost place on Earth: Antarctica.

    Ship life

    Perhaps the most common question I’ve gotten after returning from my trip is, “Did you get sea sick?” The answer is yes, but I wasn’t miserable. And in truth, very few individuals missed out on any of the shore excursions because they didn’t feel well.

    Getting there and getting around in Antarctica

    Traveling to Antarctica pretty much requires being part of an organized tour, something tens of thousands of people do each year. We went on a trip arranged by the Geological Society of America and Cheesemans’ Ecology Safaris. If you aren’t lucky enough to take a scientific tour, there are plenty of more traditional tours that will get you there. Most depart from Argentina, but some go through the Falkland Islands as well as Australia and New Zealand.
