Minimising Shipborne Emissions Along the Indian Coast

Alarming amounts of ships exhaust gases emitted worldwide forced the International Maritime Organization (IMO) to issue some restricted maritime legislation for reducing the adverse environmental impacts arising from such emissions. Consequently, ships emission reduction became one of the technical and economic challenges that the ship operators are facing. The present paper addresses the different strategies […]

Recent Developments in Shore Protection for India’s Coasts

The Indian coastline spreads over 7,500 km and is endowed with a wide variety of ecosystems, rich habitats and biodiversity. The coastal environment plays a vital role in the nation’s economy by virtue of its resources. These areas, however, are also facing complex issues due to increasing human population, urbanisation and accelerated developmental activities. Of […]

Quarter Century of Ocean Technology

The National Institute of Ocean Technology (NIOT) is the only institute in the country working on technology for the oceans. In the quarter century of its existence, the achievements are truly remarkable. Technology development has been taken up from shallow water depths to deep waters. The areas of activity encompass societal benefits, strategic needs, technology […]

Phytoplankton Blooms in the Southern Ocean: Through Satellite Observations

The oceanic phytoplankton play an important role in linking the Southern Ocean pelagic ecosystem to the global biogeochemical cycle and modulating climate change. Phytoplankton is the base of the oceanic food web, supplying organic matter for all other organisms in the marine environment. They are responsible for contributing more than 50 per cent of the […]

Designing Polar Research Vessels

Research vessels are the primary source of oceanographic observations and will remain so for the foreseeable future. Science is likely to be conducted in increasingly remote and environmentally challenging areas, including the Polar seas in the decades to come. Thus the need to build an ability to operate with minimal interruptions from natural elements remains […]

International Indian Ocean Expedition-2: A Basin-Wide Research Initiative

A flashback to the last three working days of August 1957—fifteen members of a newly organised Special Committee on Oceanic Research (SCOR, the forerunner to the present-day Scientific Committee on Oceanic Research) met at Woods Hole on Cape Cod, USA. Led by Roger Revelle, then-director of the Scripps Institution of Oceanography, California and enthused by […]

What regulates our coastline: Coastal Regulation Zone Directives

Need for restrictions on Coastal Regulation Zone India has a vast coastline with nine states and four union territories having a sea-line running along their borders. Consequently, large populations of people are dependent on the sea for their livelihood. The scenic beauty of the sea and coastal formations also attract tourists in huge numbers. Minerals […]

Decoding Pelagic Deposits

Decoding Pelagic Deposits | Red Clay and Oozes under the Ocean

What are pelagic deposits? Ocean deposits usually consist of unconsolidated sediments, which can come from various sources, and are deposited at the ocean floor. Thickness of these  deposits vary greatly from one ocean to another (Fig.1). Ocean deposits can be differentiated on the basis of their composition, source, method of transit, and mode of distribution. […]
