We were fortunate to have a Geologist on board who shared information with us about volcanoes on Antarctica.
He especially endeared himself to me at least when he made a Sheldon Cooper joke about how he knows Sheldon wouldn’t like him. To see one of Sheldon Cooper’s comments about geologists, click here.
There are 25 volcanoes in Antarctica and the sub-Antarctic Islands, mainly on the Pacific Ocean side.
Mt. Erebus, overlooking McMurdo Station (the largest U.S. base located on Ross Island), is the biggest and most southern volcano.
Last March, Zavodovski started erupting. There were 690,000 breeding penguin pairs and some were molting at the time so couldn’t get away when the ash started falling on them. More info here.
