It has been six months since I shifted home to Ghaziabad. Don’t cringe. Yes, I have left Delhi for good because the locality where I lived had started looking like a ghetto in Nazi occupied Europe. It used to be an open, green space some twenty-five years back but urbanization (which basically means cars and humans reproducing like rabbits) has choked it. Now Ghaziabad is the next upcoming destination in NCR and has some nice localities like Kaushambhi, Vasundhara, Vaishali and Indirapuram. One of them is my home now. Eventually they will turn into a ghetto too but till then I can breathe. Hell! Sometimes I feel like a well settled nomad.

Ten years ago if somebody would have hinted that I should settle in Ghaziabad, I would have frozen that guy with my stare. I would have preferred eating mud sitting comfortably in a pit full of vipers. My…

Siachen:World’s Highest Battleground

 Siachen glacier  is billed as the world’s highest combat zone, but atrocious weather conditions have claimed more lives than actual fighting. The 77-kilometre-long (48-mile) glacier traverses the Line of Control, the de facto border separating Indian- and Pakistan-controlled Kashmir, at a height of over 6,300 metres (20,800 feet). Combat between the nuclear-armed foes has claimed few lives but frostbite, avalanches and driving blizzards, which can sweep men into crevasses, are deadly for the thousands of soldiers deployed there. Winter temperatures plummet to minus 70 degrees Celsius (minus 94 Fahrenheit), with blizzards gusting at speeds of 160 kilometres (100 miles) per hour. India in 1984 occupied the key areas on the glacier, including the heights, and Pakistan immediately responded by deploying its own forces. They fought a fierce battle in 1987, raising fears of all-out conflict. New Delhi says it cannot withdraw its troops from the glacier until Islamabad recognises its troop positions, fearing Pakistan will move its soldiers forward in the event of an Indian pull-out. Experts have said there are some Indian 5,000 troops on the glacier while Pakistan has less than half that number, but there are no recent estimates. Islamabad says the presence of Indians on the glacier threatens a strategic Sino-Pakistani highway located 180 kilometres away.Most of the time on Siachen, the bad weather prevents any troop movement and despite the heavy deployment, clashes are generally low-level skirmishes involving a few dozen troops. Since both sides deployed troops on Siachen, casualties from sporadic clashes have not exceeded 150 on either side. Maintaining a military presence on remote Siachen exerts a heavy financial toll. India reportedly spends more than 40 million rupees ($800,000) daily on its Siachen deployment — excluding additional wages and bonuses. All Indian soldiers who complete a tour of duty on the glacier are awarded the “Siachen Pin” as a mark of fortitude. The Kashmir region — of which Siachen is a part — is divided between Pakistan and India and is claimed by both in full. It has triggered two of the three wars between the neighbours since independence in 1947 from Britain. Siachen is close to four of the world’s 14 peaks over 8,000 metres — K2, Broad Peak, Gasherbrum I and Gasherbrum II — all of which are on the Pakistani side of the frontline.

A Woman to Lead RISAT-1 mission of ISRO,India

 Valarmathi, who hails from Tamil Nadu state (in India), will lead RISAT-1 (Radar Imaging Satellite) mission, announced Indian Space Research Organisation (ISRO). She is the second woman scientist in India’s space history to head such a mission. T K Anuradha was the first woman scientist to head a space mission when GSAT-12 was launched on July 15, 2011.Valarmathi is the project director of RISAT-1, the first woman from the Tamil Nadu state to head such a project. Earlier, senior scientist R N Tyagi was the project director of RISAT.

 RISAT-1 is a microwave remote sensing satellite that has a Synthetic Aperture Radar and weighs about 1,850 kg. It is slated for launch by Polar Satellite Launch Vehicle– C19 (XL) this year into a 536 km orbit.

Coldest Antarctic Water AT Ocean Bottom Decreasing for Decades

Researchers have found a large reduction in the amount of the coldest deep ocean water, called Antarctic Bottom Water, all around the Southern Ocean using data collected from 1980 to 2011. These findings, in a study now online, will likely stimulate new research on the causes of this change.

It was found that Antarctic Bottom Water has been disappearing at an average rate of about eight million metric tons per second over the past few decades, equivalent to about fifty times the average flow of the Mississippi River or about a quarter of the flow of the Gulf Stream in the Florida Straits.

Antarctic Bottom Water is formed in a few peculiar  locations around Antarctica, where seawater is cooled by the overlying air and made saltier by ice formation. The dense water then sinks to the sea floor and spreads northward, filling most of the deep ocean around the world as it slowly mixes with warmer waters above it.

The world’s deep ocean currents play a critical role in transporting heat and carbon around the planet, thus regulating our climate.Previous studies have shown that the bottom water has been warming and freshening over the past few decades, now these new results suggest that significantly less amount of this bottom water has been formed during that time .

Changes in the temperature, salinity, dissolved oxygen, and dissolved carbon dioxide of this prominent water mass have important ramifications for Earth’s climate, including contributions to sea level rise and the rate of Earth’s heat uptake.
