Images from Antarctica
Lyn Irvine, marine biologist and photographer, has a passion for the outdoors and wide open spaces. This self-confessed Antarctica addict is a major contributor to the calendar — Antarctica 2007: Images of a Frozen Land, and we include some of those images in a special portfolio dedicated to Lyn’s stunning photography.
Kingston-based marine biologist Lyn Irvine, and Andy Townsend, a Hobart freelance photographer and computer programmer, have again combined forces to produce two more calendars — Antarctica 2006 [in two sizes] — celebrating the harsh beauty of the frozen continent. We highlight some of the images in their portfolio here
Volcanic ‘toothpaste’ doubles island’s size
McDonald Island, an isolated companion to Heard Island — itself a barren outpost — has doubled in size in recent weeks according to satellite photographs.
The chief scientist with the Australian Antarctic program, Professor Michael Stoddart, says it appears the volcanic eruption is not violent. “This is more like a gentle squeezing of the toothpaste tube, where the toothpaste is coming out of the top and running down the side,” he said.
“It’s a slow oozing of a very thick sticky, magma … so we’re not going to see all sorts of pyrotechnics.”
The remoteness of the area usually makes it difficult to study, with scientists relying on satellite images, which was how the recent activity was picked up.
The island is just 44 kilometres from Australia’s only other active volcano, on Heard Island, which has not erupted in recent times.
