First microplastics found in Antarctic snow
University of Canterbury researchers have published the world's first study confirming the discovery of microplastics in fresh snow in Antarctica......»»
Historic fires trapped in Antarctic ice yield key information for climate models
Researchers from the University of Cambridge and the British Antarctic Survey tracked fire activity over the past 150 years by measuring carbon monoxide trapped in Antarctic ice. This gas is released, along with smoke and particulates, by wildfires,.....»»

Antarctic heat, wild Australian winter: What"s happening to the weather, what it means for the rest of the year
Australia's south and east have seen freezing temperatures and wild weather this winter. At the same time, the continent as a whole—and the globe—have continued to warm......»»
Microplastics are everywhere, but are they harming us?
Microplastics have been found in the ocean and the air, in our food and water. They have been found in a wide range of body tissues, including the heart, liver, kidneys and even testicles......»»
Ancient Antarctic microorganisms are aggressive predators
In Antarctica there is a small lake, called Deep Lake, that is so salty it remains ice-free all year round despite temperatures as low as -20°C in winter. Archaea, a unique type of single-celled microorganism, thrive in this bitterly cold environmen.....»»
Study shows link between asymmetric polar ice sheet evolution and global climate
Joint research led by Professor An Zhisheng from the Institute of Earth Environment of the Chinese Academy of Sciences has revealed the pivotal role of the growth of the Antarctic ice sheet and associated Southern Hemisphere sea ice expansion in trig.....»»
Waters along Bar Harbor, Acadia, home to billions of microplastics
Along the shores of Acadia National Park, Bar Harbor and the Schoodic Peninsula are the vast, briny waters of Frenchman Bay. With 98 square miles of water and 39 islands, the bay is vital to shorebirds, fish, lobstermen and outdoor recreationists. Un.....»»
Elevated levels of antibiotic resistance genes should be considered a new factor of global change, researchers say
Human-caused global change is a complex phenomenon comprising many factors such as climate change, environmental contamination with chemicals, microplastics, light pollution, and invasive plants. One of the main tasks of global change biology is to i.....»»
Microbial structures in Antarctic lake could reveal more about how life evolved
In the depths of remote Antarctic lakes, communities of microorganisms are thriving where few life forms can survive. Scientists are studying structures formed by these communities to understand more about microscopic life in these extreme environmen.....»»
Mega-iceberg melt affects important marine ecosystem
Scientists have for the first time taken in-situ ocean measurements during the collapse of a giant iceberg in the sub-Antarctic. These new observations reveal how ocean ecosystems may be affected if more icebergs calve due to warmer ocean temperature.....»»
Local dragonflies expose mercury pollution patterns
A new study has unveiled surprising findings about mercury pollution: where it comes from and how it moves through the environment vary significantly depending on the ecosystem. In drier regions, most mercury is deposited through rain and snow. In we.....»»
Ground surface conditions found to impact speed and distance of leaking natural gas
When natural gas leaks from a subsurface pipeline, a ground cover of water/snow saturation, asphalt paving or a combination of these can cause the gas to migrate away from the leak site up to three to four times farther than through dry soil, a new s.....»»
As alpine glaciers melt, the corpses of long-lost climbers are being discovered in the ice
In late June, as a group of mountaineers descended a treacherous glacier high in the Peruvian Andes, they spotted a dark, out-of-place lump resting on the blinding white snow......»»
Studies unravel climate pattern impacts on the Antarctic Ice Sheet
New Monash research has untangled the influence of regional climate drivers, including the Southern Annular Mode (SAM) and the El Niño-Southern Oscillation (El Niño), on the Antarctic Ice Sheet. Snow accumulation and surface melting are two importa.....»»
Researchers use 1,000 historical photos to reconstruct Antarctic glaciers before a dramatic collapse
In March 2002, the Larsen B Ice Shelf collapsed catastrophically, breaking up an area about one-sixth the size of Tasmania......»»
To boost ocean research, some scientists are turning to superyachts
For almost two years, Robert Brewin collected data from the bow of a superyacht as it sailed pristine waters from the Caribbean Sea to the Antarctic Ocean......»»
Alaska’s top-heavy glaciers are approaching an irreversible tipping point
As the plateau of the icefield thins, ice and snow reserves at higher altitudes are lost. Enlarge / Taku Glacier is one of many that begin in the Juneau Icefield. (credit: Mauricio Handler / Getty Images) The melting of.....»»
Our clothes generate microplastics that pollute the St. Lawrence River and other bodies of water, say researchers
Our clothes are made mainly of plastic......»»
Recovery of unique geological samples sheds light on formation of today"s Antarctic ice sheet
In recent years, global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its fo.....»»
Scientists make gains in mystery of missing snow
A major field project high in Colorado's Rocky Mountains has enabled scientists to produce the most comprehensive examination to date of how snow sublimates in a mountain environment......»»
