Antarctic’s Weddell Sea loses sea-ice twice the size of Spain

Antarctic sea ice is a dynamic material that forms during winter and floats away and melts during the summer. Due to this dynamic phenomenon, the ocean around Antarctica enlarges, doubling the size of the continent in the winter months reaching over 18 million sq km (Science Daily 2020). The sea ice plays an important role […]

M N Rajeevan I Collaboration is the essence of science increasing the opportunity to work extensively

G’nY. Most of the Antarctic state parties have enacted laws for safety of their personnel and activities in Antarctic waters and land. Where does India stand in drafting an Antarctic legislation? Oceanographic research interests India is well ahead into the preparation of an Antarctic legislation. A high level quasi-legal committee has been constituted for the […]

Geopolitics of the Poles in the Anthropocene Age

 Science and politics are intricately intertwined more so in Polar Regions where science ensures access. The Antarctic Treaty has provided an excellent platform for resolving minor irritants even though some experts feel that the Treaty is lately hollowing (Hemmings, 2017). Even at the height of the cold war period when the ‘the potential for the […]

On Thin Ice: Arctic, Antarctic and the Himalayas

The melting of snow in the Arctic and Antarctic due to global warming and climate change is reported frequently. However, the melting of the Himalayan glaciers goes largely unreported, even though more people are impacted. Anomalies in temperatures, global cryosphere and sea level rise are the driving factors for negative impact on global conveyor belt […]

Psychrotrophic Metal Tolerant Bacteria for Mobilisation of Metals in Antarctic Waters

Introduction Antarctic has for a long time been viewed as a pristine environment as compared to other oceanic regions experiencing both local and global anthropogenic influences only over larger time scales (Bonner 1984, Evans et al., 2000). This remotest region of the earth is a model system where human assisted biological invasion can be understood […]

Cold-loving Bacteria from Antarctic and Arctic: Occurrence, Survival and Usefulness

Introduction Psychrophilic (cold-loving) bacteria are extremophiles that define the lower limits of temperature for the survival of life forms. They survive and multiply at temperatures as low as -20oC and rarely survive above 30oC. Such bacteria are predominant in habitats that are permanently cold, such as Antarctic, Arctic, glaciers, deep sea etc. Psychrophiles play a […]

Contrasting Climate Change in the Two Polar Regions

Introduction The Fourth Assessment report of the Intergovernmental Panel on Climate Change (IPCC) noted that the global average surface air temperature had increased by 0.65° C ± 0.2° C for the period 1901-2005 (IPCC, 2007). There is now strong evidence that anthropogenic activity in the form of increasing greenhouse gas emissions is responsible for this […]

Preserving the Perishing Paradises

Earth – the only habitable planet known to mankind so far, has been sustaining all life on it through a ‘free ecosystem facility’, fulfilling our need for air, water, natural food, fibre and shelter, selflessly. Comprised of diverse ecosystems that demonstrate a delicate balance between each component viz: atmosphere, hydrosphere, biosphere, cryosphere, lithosphere – the […]

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

Scientific activities in the Antarctic play an important role in both supporting and defining states’ political engagement with the Continent. The seven states which maintain territorial claims to Antarctic – Argentina, Australia, Chile, France, New Zealand, Norway and the United Kingdom – all operate research stations within ‘their’ zones and, even today, fund more or […]

Anthropocene Security Climate Change and the Southern Polar Region

In the light of persuasive evidence provided under the rubric of earth science system, the multifaceted challenge of anthropogenic climate change demands and deserves rethinking ‘security’ as well as ‘sovereignty’ in the ecological context of the ‘Anthropocene’; a new geological era marked by huge transformations in the biosphere caused by an unprecedented scale of human […]
