It appears that millennial scale variability in the southern high latitude region significantly modulates sub-orbital variance of cross-equatorial monsoon flow, most likely by influencing the sea surface temperatures (SST) in the tropical Indian Ocean, the scientists said.

By Dillip Pradhan Dhenkanal: She is a strong believer in destiny, but uncertainty looms large over her ambition to be the first Odia to scale all the highest peaks in all the continents of the world. Monetary constraints come in the way of her next two targets- Mount Vinson of Antarctica and Mount McKinley (also […]

Washington: NASA’s satellite to track Earth’s melting ice has revealed accurate first maps of Antarctica such that it can measure sea ice height to within an inch, the US space agency has said. Less than three months into its mission, the Ice, Cloud and land Elevation Satellite-2, or ICESat-2, is measuring the height of sea […]

Tokyo: More than 120 pregnant minke whales were killed during Japan’s latest annual hunt off the coast of Antarctica, a new report said. The report, released by the International Whaling Commission, showed that 128 out of the 333 minke whales caught during the expedition in the Southern Ocean were female, and 122 of them were […]

Washington: A geothermal heat source called a mantle plume lies deep below West Antarctica, explaining some of the melting that creates lakes and rivers under the ice sheet, confirms a new NASA study. The heat source may help explain why the West Antarctic ice sheet collapsed rapidly in an earlier era of rapid climate change, […]

San Francisco: A research team has solved a century-old mystery involving a famous red waterfall, known as Blood Falls, in Antarctica, by pointing to a source of salty water. Blood Falls, found in 1911 by the Australian geologist Griffith Taylor, is famous for its sporadic releases of iron-rich salty water from the tongue of Taylor […]

New York: Scientists have recovered a lost football-field-sized balloon with a telescope hanging beneath it from Antarctica after a year of its flight. According to the US space agency NASA, the balloon floated 39 kms above the Antarctic continent for 12 days in January 2016 until scientists sent the pre-planned command to cut the balloon. […]

The fastest-melting region of Antarctica is losing the equivalent weight in ice of Mount Everest every two years, with the melt rate of glaciers in the region tripling during the last decade, a new study has found

One of the largest glaciers on the planet, Totten, is melting due to ocean warming, a phenomenon that demonstrates the vulnerability of East Antarctica and its role in increasing the level of the oceans

Canberra: Australian scientists have used satellite imagery to capture the image of a gigantic iceberg breaking away from the Amery Ice Shelf in east Antarctica. Scripps Institution of Oceanography Professor Helen Amanda Fricker said on Tuesday: “We first noticed a rift at the front of the Ice Shelf in the early 2000s and predicted a […]

London: Almost a decade after scientists at British Antarctic Survey (BAS) first detected growth of vast cracks, a huge iceberg, more than 20 times the size of Manhattan, in Antarctica’s Brunt Ice Shelf has now broken off. The first indication that a calving event was imminent came in November 2020 when a new chasm — […]
