CHENNAI: Even though one year has lapsed after oil spill robbed fishermen of their livelihood — damaging boats, fishing gear and drop in sales — the State government is yet to compensate the affect

Scientists have found that plastic trash - ubiquitous throughout the world's oceans - massively increases the chance of disease in corals.

THIRUVANANTHAPURAM: In the wake of Ockhi cyclone, plastic debris mounted in the sea bed and shores.

Coral reefs are crucial for an ocean ecosystem but over the last few years, they have been devastated by hurricanes and disasters.

The recent increase in nanoparticle (P25 TiO2 NPs) usage has led to concerns regarding their potential implications on environment and human health. The food chain is the central pathway for nanoparticle transfer from lower to high trophic level organisms. The current study relies on the investigation of toxicity and trophic transfer potential of TiO2 NPs from marine algae Dunaliella salina to marine crustacean Artemia salina.

Kai, a three-year-old green sea turtle, was released back into the turquoise waters of the Indian Ocean off Kenya's coast this month.

25% of tanker vessel market below 20 years of age are going to be decommissioned

A group of “source” reefs have been identified that could form the basis of a life support system for the Great Barrier Reef, helping repair damage by bleaching, starfish and other disturbances.

Scientists have found plastic in the stomachs of animals living more than 10 kilometres below the ocean surface in the deepest places on Earth.

Coral reefs are among Earth’s best-studied ecosystems, yet the degree to which large predators influence the ecology of coral reefs remains an open and contentious question. Recent studies indicate the consumptive effects of large reef predators are too diffuse to elicit trophic cascades. Here, we provide evidence that such predators can produce non-consumptive (fear) effects that flow through herbivores to shape the distribution of seaweed on a coral reef.
