World should come together to protect the oceans from race of expansion, exclusion says PM Modi at UNGA

India, the US and several other world powers have been talking about the need to ensure a free, open and thriving Indo-Pacific in the backdrop of China's rising military manoeuvring in the resource-rich region.

Carbon emissions will change ocean surface climate by 2100 by 95 percent: Study

Ocean surface climates, defined by surface water temperature, acidity and the concentration of the mineral aragonite support the vast majority of sea life.

Of loitering and loss: Mourning a changed relationship with the sea, in a 'developing' city

With the coastal road slowly altering the visual and emotional landscape of Mumbai, I feel as though I'm being distanced from my sea, writes artist Gaurav Ogale in the third part of Firstpost's series, Leisure and Loiter.

Ocean surrounding Antarctica officially named world's fifth ocean by National Geographic

While other oceans are defined by their nearby continents, the Southern Ocean is defined by its current.

World Oceans Day 2021: Can we use bio-fouling organisms to extract energy from ocean waves?

Waves have enough energy that every metre of coastline could power around five average homes and more during storms.

Warming climate is driving marine animals from the equator to the poles

Warming climate is driving marine animals from the equator to the poles

Poleward migration was more pronounced north of the equator, where oceans have warmed more quickly than in the south.

Carbon might boost forest, grassland growth but absorption capacity of soil decreases

Carbon might boost forest, grassland growth but absorption capacity of soil decreases

The new study adds to growing evidence that the terrestrial carbon sink is weaker than once thought.

Climate change disrupts ocean mixing that helps store world's excess heat, CO2
science

Climate change disrupts ocean mixing that helps store world's excess heat, CO2

Increasing temperature contrast between the density of the ocean layers makes mixing harder, so oxygen, heat and carbon arent able to penetrate deep seas.

Plastic pollution: What happens to the plastic after it enters the ocean?

Plastic pollution: What happens to the plastic after it enters the ocean?

Around ten million tonnes enter the ocean, but scientists estimate that only about 0.3 million tonnes of plastic is floating at the ocean surface.

Undersea habitats to change, fragment as human-made sounds drown out their voices: study

Scientists claim to have recorded 'fewer animals singing and calling than in the past' with anthropogenic sounds fragmenting their habitats.

Around the world, 14 million tonnes of microplastics litter the ocean floors: CSIRO report

The report said that areas with more floating rubbish generally had more microplastic fragments on the seafloor.

Rising temperatures making oceans stable, reducing carbon absorption capacity warns scientists

Rising temperatures making oceans stable, reducing carbon absorption capacity warns scientists

These findings have profound and troubling implications which include potentially driving more "intense, destructive hurricanes" as ocean surfaces warm.

science

Oceans around the world have captured 10 percent of global carbon emission, new study suggests

The researchers part of the study calculated a time history of ocean-atmosphere CO2 fluxes (or movement) from 1992 to 2018.

Climate change doubles the number of low-oxygen zones in Danish seas in a year
science

Climate change doubles the number of low-oxygen zones in Danish seas in a year

Increased nutrients in the sea lead to excessive growth of plants, which ultimately leads to less oxygen as the plants die and decompose in a process known as eutrophication.

A third of land, ocean area on Earth could be protected without harming economy: Report

Conserving at least a third of the planet’s land and oceans could prevent mass extinctions and allow vital habitats to be restored.

Forests are more than the planet's lungs – they also drive winds, argues Russian physicist

If proven, the biotic pump theory could explain why the remote interiors of forested continents receive as much rain as the coasts.

Rate of climate change in deep waters of the ocean could be to be seven times faster by 2050 even if we reduce emissions

Rate of climate change in deep waters of the ocean could be to be seven times faster by 2050 even if we reduce emissions

The results also showed that no amount of carbon emission reduction can reverse the rate of change that has already taken place.
