‘Nothing but fish nests’: huge icefish colony found in Antarctic sea

Researchers make unprecedented discovery of 60m active nests while collecting data in Weddell SeaResearchers exploring Antarctica’s seabed have discovered a thriving, unprecedented colony of icefish “about a third of the size of London”.The surprise discovery of about 60 million active nests was made by a team of biologists while collecting routine data at 1.5-2.5 metres above the seafloor of Antarctica’s southern Weddell Sea. Before this discovery, the largest found colony contained only 60 nes...

Shift in atmospheric rivers could affect Antarctic sea ice, glaciers

Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica, according to new research published in the AGU journal Geophysical Research Letters.

Antarctic sea ice loss explained in new study

Scientists have discovered that the summer sea ice in the Weddell Sea sector of Antarctica has decreased by one million square kilometres -- an area twice the size of Spain -- in the last five years, with implications for the marine ecosystem. The findings are published this month (June 2020) in the journal Geophysical Research Letters.

Antarctic sea-ice models improve for the next IPCC report

All the new coupled climate models project that the area of sea ice around Antarctica will decline by 2100, but the amount of loss varies considerably between the emissions scenarios.

Benthos in the Antarctic Weddell Sea in decline

Over the past quarter-century, changes in Antarctic sea-ice cover have had profound impacts on life on the ocean floor.

New research first to relate Antarctic sea ice melt to weather change in tropics

While there is a growing body of research showing how the loss of Arctic sea ice affects other parts of the planet, a new study is the first to also consider the long-range effect of Antarctic sea ice melt. It estimates that Arctic and Antarctic ice loss will account for about one-fifth of the warming that is projected to happen in the tropics.

Scientists Will Once Again Try to Explore Alien Ecosystem Exposed by Giant Antarctic Iceberg

Last year, a team of scientists embarked on a mission to explore the seafloor exposed when a Delaware-sized iceberg popped off the Antarctic Peninsula in 2017. Frustratingly, their ship had to turn around mid-voyage thanks to impenetrable sea ice. This year, amidst near-record low Antarctic sea ice levels, another…Read more...

Antarctic Sea Ice Is In Record-Low Territory Again, and Nobody Knows Why

What’s happening to Arctic sea ice is pretty straightforward: Earth is getting warmer, and everything’s melting. But on the other side of the planet, things are more complicated, as evidenced by the latest Antarctic sea ice slump that has scientists scratching their heads.Read more...

New study provides information on the secret life of an enigmatic Antarctic apex predator

Scientists from British Antarctic Survey (BAS) have, for the first time, tracked the lives of leopard seals as they migrate around Antarctica. The team followed these formidable predators as they move from the frozen Antarctic sea-ice to the more northerly sub-Antarctic islands where they prey on penguins, seals and krill. The study is published this week in the journal PLOS ONE.

This Is Why Antarctic Sea Ice Crashed This Year

The disappearance of Arctic sea ice is a well-documented trend with a well-established cause. But this past summer, Earth scientists were startled to see Antarctic sea ice take a nosedive, too. Now, scientists at the British Antarctic Survey are blaming the event on a spate of freak weather, underscoring how much we…Read more...

Boaty McBoatface Has Returned From Its Inaugural Mission With a Trove of Data

The world’s most famous yellow submarine has returned home after a successful mission to Antarctica’s Weddell Sea. Expedition organizers say Boaty McBoatface captured “unprecedented” data during its maiden voyage, analyzing deep sea currents at depths exceeding 13,000 feet. Read more...

Antarctic Sea Ice Crashed This Year and Scientists Don't Know Why

Just about every month, it seems, we get a report on the dismal state of Arctic sea ice. By contrast, the shiny white stuff surrounding the Antarctic continent has been remarkably stable in a warming world. This year, however, the sea ice at our planet’s south pole is crashing, and scientists don’t know why.Read more...

New Antarctic ice discovery aids future climate predictions

A team of British climate scientists comparing today's environment with the warm period before the last ice age has discovered a 65% reduction of Antarctic sea ice around 128,000 years ago. The finding is an important contribution towards the challenge of making robust predictions about the Earth's future climate.

Antarctic sea-ice bacteria could be contaminating seafood with a dangerous form of mercury

Pollution in the Antarctic may not turn many heads, but seafood lovers must beware of mercury-tainted fish from the southern seas finding its way onto their plates. New research shows how a certain type of sea-ice bacteria may be converting existing mercury into an even more potent neurotoxin that is harmful to the environment, marine life, and those higher up the food chain. A study published in the journal Nature discovered how the Nitrospinia bacterium is turning mercury into methylmercury...
