A study in Scientific Reports shows the potential of passive microwave observations from satellites to estimate the thickness and winter volume of Arctic sea ice. The sea ice, formed by freezing ...

Changes in Arctic sea ice volume affect regional heat and freshwater budgets and patterns of atmospheric circulation at lower latitudes. Despite a well-documented decline in summer Arctic sea ice ...

Until now that system has gone back only as far as 1979. A new paper now extends the estimate of Arctic sea ice volume back more than a century, to 1901. To do so it used both modern-day computer ...

"With slow progress over the past few decades, additional measures may buy us time." Scientists prep bold experiments to ...

Arctic pack ice. The Arctic is warming at a rate up to four times faster than the planet as a whole and has lost a third of its sea ice volume in just two decades. Image by Markus Trienke via ...

Arctic sea ice declined dramatically in 2007 and ... Underwater radar systems can detect the volume of ice flowing overhead, while satellites and buoys track the movement of ice and the length ...

Arctic sea ice also hit a record low seasonal peak for sea ice volume, which is a measure of the thickness of the ice. This record indicates that the ice cover present in the Arctic is young and ...

Past studies concentrated more on the extent of Arctic sea ice, or how widespread it is, because that's easily measured by satellites, which don't observe volume well. But 90% of the sea ice ...

What are the polar research base stations of India? What is the significance of the Maritime Development Fund?

The “wide coverage of this thinner ice” means total Arctic sea ice volume for the month of February was the third lowest on record. Arctic sea ice extent changes throughout the year. It grows each ...

NASA researchers have documented the loss of trillions of tons of ice from Earth's poles due to human-driven climate change. However, a meme began circulating again in late 2021, claiming "NASA ...
