Cabinet has approved the new draft National Marine Pollution Contingency Plan (NMPCP) to better deal with marine pollution, not only from oil spills in Namibian waters but also from hazardous and n

Intensifying climate change remains the biggest threat to coral reefs around the world, with rising sea surface temperatures driving widespread bleaching events, according to the Climate Council’s latest report.

A draft report on the state of three marine outfalls has been completed.

CHENNAI: The investigation of how much oil was leaked into the sea has been hit even as as efforts are on to transfer the oily water from one of the tanks of MT Dawn Kancheepuram, which collided wi

The Strategic Plan for Biodiversity, adopted under the auspices of the Convention on Biological Diversity, provides the basis for taking effective action to curb biodiversity loss across the planet by 2020—an urgent imperative. Yet, Antarctica and the Southern Ocean, which encompass 10% of the planet’s surface, are excluded from assessments of progress against the Strategic Plan. The situation is a lost opportunity for biodiversity conservation globally. We provide such an assessment.

Degradation of coastal water quality in the form of low dissolved oxygen levels (hypoxia) can harm biodiversity, ecosystem function, and human wellbeing. Extreme hypoxic conditions along the coast, leading to what are often referred to as “dead zones,” are known primarily from temperate regions. However, little is known about the potential threat of hypoxia in the tropics, even though the known risk factors, including eutrophication and elevated temperatures, are common.

During 2015–2016, record temperatures triggered a pan-tropical episode of coral bleaching, the third global-scale event since mass bleaching was first documented in the 1980s. Here we examine how and why the severity of recurrent major bleaching events has varied at multiple scales, using aerial and underwater surveys of Australian reefs combined with satellite-derived sea surface temperatures. The distinctive geographic footprints of recurrent bleaching on the Great Barrier Reef in 1998, 2002 and 2016 were determined by the spatial pattern of sea temperatures in each year.

Tropical cyclones and sea level rise cause major problems including beach erosion and damage to infrastructure in coastal areas. Inexpensive but effective plans for coastal protection will be needed by small island nations and developing countries. Natural breakwater formed by reefs is more cost-effective in coastal protection than the construction of artificial defenses. It provides a habitat for marine organisms and societal benefits including marine products, tourism, and education.

There were startling colours here just a year ago, a dazzling array of life beneath the waves. Now this Maldivian reef is dead, killed by the stress of rising ocean temperatures.

Question raised in Rajya Sabha on Damage to Marine Ecosystem, 09/03/2017. The Ministry has been implementing a program for assessment of health of the coastal waters of India by periodically monitoring the pollutant levels in the seawaters of India.
