Government unveils blueprint of Deep Ocean Mission

Union Ministry of Earth Sciences has unveiled blueprint of Deep Ocean Mission (DOM). The mission proposes to explore deep-ocean by emulating success of Indian Space Research Organisation (ISRO) in designing and launching satellites. For this mission, Centre has drawn up a five-year, Rs. 8,000 crore plan to explore deep recesses of the ocean.

Features of Mission

The focus of DOM is on deep-sea mining, ocean climate change advisory services, underwater vehicles and underwater robotics related technologies. Two key projects planned under it include desalination plant powered by tidal energy and submersible vehicle that can explore depths of at least 6,000 metres.

Background

India’s Exclusive Economic Zone (EEZ) spreads over 2.2 million sq. km and in the deep sea, lies unexplored and unutilised. Besides, India has been allotted site of 1,50,000 sq. km in Central Indian Ocean Basin (CIOB) by United Nations International Sea Bed Authority (UN-ISBA) for exploitation of polymetallic nodules (PMN). These are rocks scattered on seabed containing iron, nickel, manganese and cobalt. It is envisaged that 10% of recovery of that large reserve can meet energy requirement of India for next 100 years. It has been estimated that 380 million metric tonnes of polymetallic nodules are available at the bottom of the seas in CIOB.

SAFAR: Most advanced System of Air Quality and Weather Forecasting inuagrated in Delhi

Ministry of Earth Sciences has unveiled state-of-the-art Air Quality and Weather Forecast System– SAFAR (System of Air Quality and Weather Forecasting) at Chandni Chowk in Delhi. It is first of its kind and most advanced system in India. Such advanced are also proposed to be implemented in other three cities of India- Pune, Mumbai and Ahmedabad.

SAFAR (System of Air Quality and Weather Forecasting)

SAFAR was developed indigenously by Indian Institute of Tropical Meteorology (IITM), Pune and operationalized by India Meteorological Department (IMD). It is integral part of India’s first Air Quality Early Warning System operational in Delhi. It will monitor all weather parameters like temperature, rainfall, humidity, wind speed and wind direction.

It also will measure sun’s UV-Index (UVI), PM1, Mercury and Black carbon in real time in addition to regular air quality and weather parameters like PM2.5, PM10, Sulfur Dioxide, Ozone, Nitrogen Oxides, Carbon Monoxide. It can also provide measurement of online automatic ultrafine particles PM1 and Mercury, both of which have direct relevance to human health. It will also monitor existence harmful pollutants of Benzene, Toluene and Xylene.

SAFAR has giant true colour LED display which gives out real-time air quality index on 24×7 basis with colour coding alongwith 72-hour advance forecast. Based on Air Quality Index on particular day, health advisory and related precaution will be notified to prepare citizens well in advance.

Benefits

SAFAR will accelerate public awareness and preparedness of air pollution and weather extremes. It will also lead to better understanding of linkages among emissions, weather, pollution and climate. It will strengthen existing air quality network of SAFAR, Central Pollution Control Board (CPCB) and Delhi Pollution Control Committee (DPCC). Besides health, SAFAR system will benefit cost savings to several other sectors like agriculture, aviation, infrastructure, disaster management skill, tourism and many others, which directly or indirectly get affected by air quality and weather.
