Iceberg from Larsen C Ice Shelf threatens penguins on South Georgia Island

Satellite imagery shows the iceberg, shaped like a finger pointed in its direction of travel, headed toward South Georgia Island. It measures about 95 miles in length and 30 miles in width, making it roughly equivalent to the size of the island itself. It is now located less than 300 miles from the island, NASA found.

According to David Long, a Brigham Young University professor who tracks polar ice using satellite imagery, the iceberg is sizable enough that if it becomes grounded in shallow waters off the island’s eastern shore, it could make it difficult for native wildlife to forage for food.

Geraint Tarling, an ecologist at the British Antarctic Survey, said in a news release that the iceberg could have “massive implications” for local species, especially if it is there for a long time.

“When you’re talking about penguins and seals during the period that’s really crucial to them

Blue whales return to sub-Antarctic island of South Georgia after near local extinction — ScienceDaily

An international research team led by UK scientists has revealed the return of critically endangered Antarctic blue whales to the sub-Antarctic island of South Georgia, 50 years after whaling all but wiped them out. The new study follows recent research that humpback whales are also returning to the region.

The discovery, based on analysis of 30 years’ worth of sightings, photographs and underwater sound recordings, is crucial evidence in learning how the species is recovering following a ban on commercial whaling in the 1960s. The findings are published today (19 November) in the journal Endangered Species Research.

Blue whales were abundant off South Georgia before early 20th century industrial whaling between 1904 and 1971 killed 42,698 of them there. Most of these were killed before the mid-1930s.

The species all but vanished from the region — dedicated whale surveys from ships off South Georgia resulted in only a single

Trees and green roofs can help reduce the urban heat island effect — ScienceDaily

Air pollution experts from the University of Surrey have found that green infrastructure (GI), such as trees, can help reduce temperatures in many of Europe’s cities and towns.

An urban heat island is an urban area that is significantly warmer than its surrounding rural areas. The temperature difference is typically larger at night than during the day.

With the UK government pledging to build 300,000 new homes every year, it is feared that many of the country’s towns and cities will experience an increase in temperature brought about by more vehicles and building activity.

In a paper published by Environmental Pollution, experts from Surrey’s Global Centre for Clean Air Research (GCARE) modelled how a UK town would be affected if its urban landscape included different types of GI.

The study focused on simulating temperature increases in the town of Guildford, UK, under different GI cover (trees, grassland and green

Fossil bones collected in the early 1990s on Henderson Island, part of the Pitcairn Group, have revealed a new species of Polynesian sandpiper.

The Henderson Sandpiper, a small wading bird that has been extinct for centuries, is described in an article in the Zoological Journal of the Linnean Society published last week.

The newly-described bird is formally named Prosobonia sauli after Cook Islands-based ornithologist and conservationist Edward K Saul.

A team of researchers from New Zealand, Australia, Denmark, Switzerland, the Netherlands and China, led by Canterbury Museum Research Curator Natural History Dr. Vanesa De Pietri, described the Henderson Sandpiper from 61 fossilised bones cared for by the Natural History Museum at Tring in England.

Canterbury Museum Visiting Researcher Dr. Graham Wragg collected the bones from caves and overhangs on

Iceberg Headed for Sub-Antarctic Island Could Threaten Wildlife

An iceberg roughly the size of Delaware that is headed toward the sub-Antarctic island of South Georgia has experts worried about the possibility of it blocking wildlife from food sources and threatening the island’s ecosystem.

The iceberg, known as A68a, was about 400 kilometers, or about 250 miles, away from the coast of the British island territory of South Georgia as of Wednesday, the British Antarctic Survey said.

The iceberg may run aground near the island and be a few weeks out from the island’s coast, said Andrew Fleming, a remote sensing manager with the survey.

Delaware-Sized Iceberg Could Decimate Wildlife on South Atlantic Island | Smart News

A hulking block of ice adrift in the frigid South Atlantic is on a collision course with the island of South Georgia, a British Overseas Territory, and a direct hit could have disastrous implications for local wildlife, reports Jonathan Amos for BBC News.

The iceberg, known as A68a, cut loose from Antarctica’s Larsen C Ice shelf in July 2017, reports Kara Fox of CNN. At 1,815 square miles, A68a is slightly larger than South Georgia itself and weighs “hundreds of billions of tons” per BBC News.

“It is absolutely huge and it’s the largest iceberg around in the Southern Ocean,” Sue Cook, a glaciologist at the Australian Antarctic Program Partnership, tells Graham Readfearn of the Guardian.

After drifting around 870 miles north through “iceberg alley,” A68a is presently about 300 miles southwest of the island, which hosts large populations of seals, penguins and albatross. Though the berg’s final path

Seabirds’ response to abrupt climate change transformed sub-Antarctic island ecosystems — ScienceDaily

The Falkland Islands are a South Atlantic refuge for some of the world’s most important seabird species, including five species of penguins, Great Shearwaters, and White-chinned Petrels. In recent years, their breeding grounds in the coastal tussac (Poa flabellata) grasslands have come under increasing pressure from sheep grazing and erosion. And unlike other regions of the globe, there has been no long-term monitoring of the responses of these burrowing and ground nesting seabirds to climate change.

A 14,000-year paleoecological reconstruction of the sub-Antarctic islands done by an international research team led by The University of Maine (UMaine) including Dr Moriaki YASUHARA from the School of Biological Sciences and The Swire Institute of Marine Science, The University of Hong Kong (HKU), has found that seabird establishment occurred during a period of regional cooling 5,000 years ago. Their populations, in turn, shifted the Falkland Island ecosystem through the deposit of high concentrations

Ancient flint tools buried in the slopes of a Danish island have offered a hint that Neanderthals may have lived there 120,000 years ago. 

The first humans in Denmark were previously believed to have been reindeer hunters from around 14,000 years ago.

Archaeologists from Denmark’s National Museum and Roskilde Museum excavated slopes in Ejby Klint by Isefjord between Roskilde and Holbæk.

The researchers found ancient mussel shells and flint stones that may have been shaped by humans. 

Ejby Klint is one of the few places in Denmark where archaeologists can easily find layers in the earth from a warm period between two ice ages 115,000-130,000 years ago.

Two decades of data from a study of Maine’s Swan’s Island document a slow and steady dwindling of mussels, barnacles, and snails — ScienceDaily

The waters of the Gulf of Maine are warming faster than oceans almost anywhere on Earth. And as the level of carbon dioxide rises in the atmosphere, it’s absorbed by the oceans, causing pH levels to fall. Ocean acidification makes it difficult for shellfish to thicken their shells — their primary defense against predators.

In a new study in the journal Communications Biology, researchers Peter Petraitis, a retired professor of biology in Penn’s School of Arts & Sciences, and Steve Dudgeon, a biology professor at California State University, Northridge, who completed a postdoctoral fellowship with Petraitis at Penn in the 1990s, show that the changing climate is taking a toll on Maine’s sea life. A dataset collected over two decades, including numbers of five species of mussels, barnacles, and snails, shows that all have been experiencing declines — some slow, some more rapid — in part owing to climate
