Deep Ocean Mission
Government of India is all set to launch ‘Deep Ocean Mission’ by January 2018 and it will improve India’s position in ocean research field.
Achievements in the field of ocean research: The program on Poly metallic nodules was initiated at CSIR-NIO with the collection of the first nodule sample from Arabian Sea on board the first Research Vessel Gaveshani on 26 January 1981.
India was the first country in the world to have been given the Pi
When the Indian Ocean’s ancient climate patterns return
About 19,000-21,000 years ago, ice-sheets covered North America and Eurasia, and sea-levels were much lower, with Adam’s Bridge exposed so that the Indian subcontinent and Sri Lanka were contiguous.
This period, the peak of ice age conditions, is called the Last Glacial Maximum.
Researchers analysed simulations of this past climate and predicted that the ongoing climate change could reawaken an ancient clim
Sea Level Rise: Its impact
GS-PAPER-1 Geography: Oceanography (PT-MAINS)
Recently, a study in journal Scientific reports made predictions that a large population and assets will be globally affected as a consequence of Sea Level Rise (SLR).
SLR is a consequence of climate change, which is predicted to increase coastal flooding by 2100.
The global population potentially exposed to episodic coastal flooding will increase from 128-171 million to 176-287 million by 2100
The Gulf Stream, together with its northern extension the North Atlantic Drift, is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida.
It then follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean as the North Atlantic Current.
The Gulf Stream system conveys warm surface water from equator to the north and the deep
