Warm ocean melting East Antarctica’s largest glacier

The largest glacier in East Antarctica, containing ice equivalent to a six-metre (20-foot) rise in global sea levels, is melting due to warm ocean water, Australian scientists said on Monday.

The 120-kilometre (74.4 mile) long Totten Glacier, which is more than 30 kilometres wide, had been thought to be in an area untouched by warmer currents. But a just-returned voyage to the frozen region found the waters around the glacier were warmer than expected and likely melting the ice from below. “We knew that the glacier was thinning from the satellite data, and we didn’t know why,” the voyage’s chief scientist Steve Rintoul told AFP.

He said that up until recently the East Antarctica ice sheet had been thought surrounded by cold waters and therefore very stable and unlikely to change much. But the voyage found that waters around the glacier were some 1.5 degrees Celsius warmer than other areas visited on the same trip during the southern hemisphere summer. “We made it to the front of the glacier and we measured temperatures that were warm enough to drive significant melt,” Rintoul said. “And so the fact that warm water can reach this glacier is a sign that East Antarctica is potentially more vulnerable to changes in the ocean driven by climate change than we used to think.”

Previous expeditions had been unable to get close to the glacier due to heavy ice, but Rintoul said the weather had held for the Aurora Australis icebreaker and a team of scientists and technicians from the Australian Antarctic Division and other bodies.

Volcanos

Roundup of Global Volcanic Activity

Kliuchevskoi (Kamchatka): The eruptive activity has weakened a bit, but remains near-continuous. Small ash emissions from strombolian activity occurred yesterday and bright glow from this activity illuminates the volcano’s summit at night.

No lava flow seems to be active at the moment.

Shiveluch (Kamchatka): A strong vulcanian-type explosion occurred this morning. An ash plume rose to approx. 25,000 ft (7.5 km) altitude and a pyroclastic flow seems to have descended to the SE.

Zhupanovsky (Kamchatka, Russia): Intermittent ash emissions continue. A plume at 10,000 ft (3 km) altitude was detected extending SSE on satellite imagery this morning (Tokyo VAAC).

Suwanose-jima (Ryukyu Islands): Occasional strombolian eruptions occur from time to time. An explosion was reported yesterday (Tokyo VAAC).

Dukono (Halmahera): Significant ash emissions were observed again this morning. Tokyo VAAC reported a plume extending 20 nautical miles to the SW, at estimated 10,000 ft (3 km) altitude.
