Polar Perspectives

Polar Geopolitics-Security, Sovereignty and Stewardship

By: Prof Klaus Dodds

An unbiased institutional body working as an overseer and comprising of a legislative organ to construct and modulate strong political frameworks and agendas that demand sustainable approach in the exploration and exploitation of the rare and precious resources of the Polar Region is the need of the hour.

Science and the Antarctic: Resource Exploitation, Regulatory Lacunae and Environmental Security

By: Prof Karen Scott

Antarctic has arguably been ‘constructed through science’ as a geopolitical and legal space and science has been used as a surrogate for effective occupation, supporting the ‘colonisation’ of Antarctic. Yet science also provided both the motive and the means to negotiate and adopt, at the height of the Cold War, the 1959 Antarctic Treaty, under the auspices of which, a successful, effective and enduring management regime for Antarctic has been developed.

Iron Fertilisation Experiments in the Southern Ocean

By: Prof V Smetacek and Dr SWA Naqvi

Of the various macro-engineering schemes proposed to mitigate global warming, ocean iron fertilisation is one that could be started at short notice on relevant scales. It is based on the reasoning that adding trace amounts of iron to iron-limited phytoplankton of the Southern Ocean will lead to blooms, mass sinking of organic matter and ultimately sequestration of significant amounts of atmospheric carbon dioxide in the deep sea and sediments.

Antarctic Krill-Extraction and Storage

By: Dr C N Ravishankar

Antarctic krill is found in huge swarms in the waters of the Southern Ocean. The krill despite being a promising source of protein is still largely unfit for human consumption due to its high fluoride content, blackening and unpleasant flavour.

Fortunes under the Sea

By: Staff Reporter

Oceans hold precious resources buried in seabeds and continental shelves. Despite legislations and international bodies upholding the Law of the Seas, fear about restrain of rights has begun to grow in developing nations with technologically advanced countries leading exploitation activities.

Arctic Conventions

By: Staff Reporter

Arctic Conventions Climate change, the most significant stress on the Arctic is likely to impact the entire world as climate systems are all intricately linked. The essay attempts to understand the legal mechanisms that are functioning in the region dealing with the many uncertainties in the wake of a warming trend.

Antarctic Treaty System

By: Staff Reporter

The Antarctic Treaty System (ATS) is a complex legal instrument that enlists measures in effect and its associated international instruments. Freedom of scientific research is enshrined in the Treaty and hence the ATS promotes free exchange of scientific information and mandates that observations from Antarctic must be made freely available.

Eroding identities of Kashmir’s Bakarwal

By: Mohd Tufail

Bakarwal, one of the largest nomadic Muslim tribes of India inhabits the militancy ridden vales of beautiful Kashmir and traces their ancestry to Georgia and other Central Asian Countries. The tribe in the last few decades is rapidly losing its identity and is struggling for survival in the midst of the crisis that has shrouded the Valley since the early 1990s.

Eco-Friendly Plastics

By: Dipanjan Ghosh and Sreeparna Ghosh

Bioplastic is an important and exciting new field in biotechnology which promises to help in saving the environment and slow down the depletion of non renewable resources. Bioplastics may be derived from biomass sources, such as vegetable fats and oils, corn starch, pea starch etc., rather than fossil fuel plastics which are derived from petroleum. However not all bioplastics are designed to biodegrade.

Man-Animal Conflict-A Rising Concern

By: Kamal Kishore Srivastava

Man-animal conflicts are on the rise. The diminishing and depleting forest areas, habitat degradation, fragmentation of the forests and vanishing corridors are forcing wild animals to move out in to the open. The result is man-animal conflict and a irreplaceable loss of India’s vibrant biodiversity. With disrupted food chains, and an ever increasing population demanding more and more land, ecosystems are degrading with a rapidity that is astounding.

India's Outdoors

By the Sea: Maldives

By: S Srinivasan

The Maldives with a population of 270,000 has been isolated from the outside world for much of its history. The affable people here have adapted to island life with the main source of nutrition being fish, coconut and imported rice.

Chhattisgarh Dance and Music

By: Staff Reporer

Home to myriad tribes that trace their ancestry to mythological times, songs, dances and plays of the State of Chhattisgarh are unique and indeed a treat for the senses. The beat of the drums and lilting flutes beckon you to a world of unexplored charm.

In brief

Polar Roundup

Often termed as the barometer of world climate, the polar region is an area of active debate and research. A few updates on the research front are summarised here.

Editor's Note

Dear readers, Chaos reigns our office nowadays. Partnered with LIGHTS Research Foundation, we are all set to organise the International Conference of Science and Geopolitics, i-SaGAA 2012, at New Delhi on 9-11 March 2012. Why did we choose to work on polar issues? Well, we feel that new and signifi

What is ...

A large depression produced by thawing of a huge area of very thick and exceedingly ice-rich permafrost. The sides of an alas are smooth and slippery, hence making navigation difficult. Found in both the Arctic and the Antarctic region.

German for ‘ice on top’, it is a sheet-like mass of layered ice that forms from successive flows of ground water during freezing temperature. Aufeis accumulates in the winters along stream and river valleys in Arctic and subarctic regions.

The crevasse usually formed where glaciers located in armchair like depressions - cirque, moves away from the head wall which may be the solid rock of a mountain slope or a stable glacier.

Alternate bands of light and dark on a glacier, usually found below steep narrow icefalls as the possible result of different flow and ablation rates between summer and winter. Not all icefalls however have band ogives below them.

A nunatak is an exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier. Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named.

An area of open water in pack or sea ice, polynyas may be kept open by constant winds or upwelling of water and so tend to recur in the same location year after year. They are particularly important for wildlife as they allow mammals such as whales and seals to have a breathing hole.

Paleoclimatology (also palaeoclimatology) is the study of changes in climate taken on the scale of the entire history of Earth. It uses a variety of proxy variables to obtain data previously preserved within (e.g.) rocks, sediments, ice sheets, tree rings, corals, shells and microfossils.

The Bellingshausen Sea is an area along the west side of the Antarctic Peninsula, west of Alexander Island, east of Cape Flying Fish on Thurston Island, and south of Peter Island. Bellingshausen Sea has an area of 487,000 km2 and reaches a maximum depth of 4,470 meters.

Permafrost is the soil which has been at or below 0°C for more than two years. Ice is not always present, as may be in the case of nonporous bedrock, but it frequently occurs and it may be in amounts exceeding the potential hydraulic saturation of the ground material.

Arctic haze is the phenomenon of a visible reddish-brown haze in the atmosphere at high latitudes in the Arctic due to air pollution. Due to limited amounts of snow, rain, or turbulent air to displace pollutants from the polar air mass in spring, Arctic haze can linger for more than a month in the northern atmosphere.

Irregular ridges of snow which lie parallel to the direction of the wind. Sastrugi can make travel very awkward. Rarely higher than a foot, they can be quite soft or as hard as ice.

Thick ridges that become grounded in the winter and become part of the fast ice zone. While the rest of the fast ice melts in the summer, stamukhi remains intact throughout the summer attached to the ocean floor.

Maitri is India’s second permanent research station in Antarctica. It was built and finished in 1989, shortly before the first station Dakshin Gangotri was buried in ice and abandoned in 1990-91. Maitri is situated on the rocky mountainous region called the Schirmacher Oasis.
