To strengthen India’s research base in Antarctica, the government today authorised the National Centre for Antarctic and Ocean Research (NCAOR), Goa to acquire a Polar Research Vehicle (PRV) at the cost of Rs 1051 crore.

“The Cabinet Committee on Economic Affairs (CCEA) had approved acquisition of the Polar Research Vessel (PRV) in October last year at an estimated expenditure of over Rs. 1051 crore,” Minister of State for Earth Sciences YS Chowdary said.

He said the vessel is expected to contribute to India’s scientific expeditions and to sustain research at two Indian bases in Antarctica (Maitri and Bharti) and also dovetail research initiatives in the Southern Ocean domain in the proximal regions of the Antarctic continent.

“Taking into consideration the growing need of the scientific community to initiate studies in the frontier realms of ocean sciences, and the uncertainty in the charter-hire of polar vessels and the ever-escalating chartering costs it was decided to explore the feasibility of constructing and commissioning a polar research vessel which can cater to both the scientific and logistics aspects of the polar and Southern Ocean programmes,” the minister said, and added, that the PRV will give an expansion to our scientific activities into the Arctic and Southern Ocean.

“It could also widen the thrust on Arctic research disciplines, undertaken through Indian Station Himadri, in addition to providing a suitable research platform for other ocean research programmes,” Chowdary said.

Ever since the first Indian Scientific Expedition to Antarctica began way back in 1981, India has been managing the transportation of the expedition personnel and cargo to and back from Antarctica through chartered vessels.

ESA Observes Strong Reduction in Ozone Concentrations Over Arctic

Satellite Indicates 'Mini-Hole' in Arctic Ozone Layer

Scientists studying data from a European Space Agency (ESA) satellite say they have observed a strong reduction in ozone concentrations over the Arctic, creating what they are calling a “mini-hole” in the ozone layer.

The ozone layer is a natural, protective layer of gas in the stratosphere that shields life from the sun’s harmful ultraviolet radiation, often associated with skin cancer and cataracts, as well as other environmental issues.

The “ozone hole” most often referenced is over Antarctica, forming each year. But observations scientists made at the German Aerospace Center in the last week indicate ozone depletion over northern polar regions as well.

The scientists refer to the Arctic depletion zone as a “mini-hole” because it has a maximum extension of less than a million square kilometers, which is tiny compared with the 20 million- to 25 million-square-kilometer hole that forms over the Antarctic.

Ice Loss in Antarctica and Greenland Increasing at an Alarming Rate: Scientists

Greenland, Antarctica ice loss accelerating

Earth’s great ice sheets, Greenland and Antarctica, were now losing mass six times faster than they were in the 1990s due to warming conditions, the media reported on Thursday citing scientists as saying.

A comprehensive review of satellite data acquired at both poles was unequivocal in its assessment of accelerating trends, the BBC quoted the scientists as saying.

Between them, Greenland and Antarctica lost 6.4 trillion tonnes of ice in the period from 1992 to 2017.

This was sufficient to push up global sea-levels up by 17.8 mm, the scientists added. “That’s not a good news story,” said Professor Andrew Shepherd from the University of Leeds.

“Today, the ice sheets contribute about a third of all sea-level rise, whereas in the 1990s, their contribution was actually pretty small at about 5 per cent. This has important implications for the future, for coastal flooding and erosion,” he told BBC News.

The researcher co-leads a project called the Ice Sheet Mass Balance Intercomparison Exercise, or Imbie, which is a team of experts who have reviewed polar measurements acquired by observational spacecraft over nearly three decades.

The Imbie team’s studies have revealed that ice losses from Antarctica and Greenland were actually heading to much more pessimistic outcomes, and will likely add another 17 cm to those end-of-century forecasts.

“If that holds true it would put 400 million people at risk of annual coastal flooding by 2100,” Professor Shepherd told the BBC.

High Temperature Records in Antarctica will Take Months to Verify: UN

Antarctic High Temp Records Will Take Months to Verify, says the UN Weather Agency

Record high temperatures reportedly measured in Antarctica will take months to verify, the U.N. weather agency said Sunday.

A spokesman for the World Meteorological Organization said the measurements made by researchers from Argentina and Brazil earlier this month have to undergo a formal process to ensure that they meet international standards.

“A formal decision on whether or not this is a record is likely to be several months away,” said Jonathan Fowler, the WMO spokesman.

Scientists at an Argentine research base measured a temperature of 18.3° C (nearly 65° F) Feb. 6 on a peninsula that juts out from Antarctica toward the southern tip of South America. Last week, researchers from Brazil claimed to have measured temperatures above 20° C on an island off the peninsula.

Fowler said both measurements would need to be transmitted to Prof. Randall Cerveny, a researcher at Arizona State University who examines reported temperature records for WMO.

Cerveny then shares the data with a wider group of scientists who “will carefully evaluate the available evidence (including comparisons to surrounding stations) and debate the merits and problems of the observation,” said Fowler.

The evaluation normally takes six to nine months, after which Cerveny would “formally either accept or reject the potential extreme,” giving official WMO approval to the new record, he said.
