NDTV Exclusive: Inside India's Ocean Research Vessel Sagar Manjusha
NDTV spent nearly 30 hours onboard India's ocean research vessel ORV Sagar Manjusha, witnessing live scientific experiments in the Arabian Sea and getting an inside look at how researchers study the ocean floor.

Record-Breaking Drill Beneath Antarctic Ice Reveals Ancient Open Ocean and Future Sea Level Risks
Scientists drilled deeper than ever beneath the West Antarctic Ice Sheet and found sediment and marine remains showing the area was once open ocean. The 23-million-year record offers key clues about past melting, helping researchers better predict how quickly the ice sheet could retreat and affect future global sea levels.

Sinking Calcium Carbonate Locked Away Greenhouse Gases, Reveals New Study
Scientists have solved a 66-million-year climate mystery, explaining how Earth cooled from a tropical greenhouse to an ice-capped world. New research reveals ocean calcium levels dropped by more than half, reshaping marine chemistry. As calcium declined, oceans locked away more carbon dioxide, lowering atmospheric CO2. The study links deep-Earth pr...

Fossils From The Arctic Reveal Ocean-Dwelling Reptiles Of The Dinosaur Age
Researchers collected samples from a 36-square-meter area, recovering over 800 kilograms of material.

Researchers Develop Wetsuits That Protect Against Shark Bites And Stings
Australian researchers have tested new bite-resistant wetsuits that minimize injuries from shark bites. The materials, made with chain mail, Kevlar, and nanofibers, help reduce bleeding and improve safety for surfers and divers. The innovation marks a step forward in shark bite protection without limiting flexibility underwater.

Whales And Dolphins Frequently Hang Out With Each Other: Study
As the annual humpback whale migration is underway with thousands of whales passing by the Australian coast, there are reports of dolphins joining the mass movement.

Greenland's Melting Glaciers Feed Ocean Life, Study Finds
A new NASA-led study reveals that Greenland’s melting glaciers are fueling life in the Arctic Ocean. Each summer, massive freshwater plumes from glaciers like Jakobshavn drag deep-sea nutrients upward, boosting phytoplankton growth by up to 40%. These microscopic organisms form the base of the marine food web and play a key role in carbon absorpt...

5 Arms, No Eyes, No Heart: DNA Revealed Weird Deep-Sea Brittle Star Journey
You may have read that the deep sea is a very different environment from the land and shallow water. There is no light, it is very cold, and the pressure of all the water above is immense.

AI Designs Ocean Gliders Inspired by Sea Creatures to Boost Underwater Research Efficiency
Researchers at MIT and the University of Wisconsin have developed AI-designed underwater gliders inspired by marine animals. The new shapes, generated using machine learning, move more efficiently underwater than traditional torpedo designs. This innovation could greatly improve climate and ocean monitoring by enabling better performance, energy sa...

Hundreds Of New Giant Viruses Discovered In Global Waters: Study
The study identified 230 new giant viruses and 530 novel functional proteins, shedding light on their interactions with marine microbes and potential biotechnological applications.

Scientists Discover Clicking Sounds in Rig Sharks for the First Time
Sharks were long thought to be silent, but a surprising new study reveals that rig sharks can make clicking sounds when handled. Evolutionary biologist Carolin Nieder first discovered the clicks by accident during lab tests. These sounds—likely produced by snapping their flat teeth—occurred most often during initial handling, suggesting a stres...
