Study of ancient rocks suggests oxygen depletion in oceans led to end-Triassic mass extinction

A team of researchers from the U.K., China, and Italy has found evidence that suggests oxygen depletion in the world’s oceans led to the end-Triassic mass extinction. In their paper published in the …

‘Dead Zones’ Multiplying In World’s Oceans

‘Dead Zones’ Multiplying In World’s Oceans A global study shows the number of “dead zones” — areas of ocean with too little oxygen for most marine life — has increased by one-third since 1995 …

The Ocean’s “Dead Zones” Could Be Getting A Lot Worse

There are over 400 coastal dead zones around the world, regions so poor in dissolved oxygen that marine life can’t survive during the summer months. And it looks like these dead zones will be …

World’s oceans are capturing twice as much carbon as previously thought thanks to microscopic carbon-loving plankton that float down to the ocean depths, study claims

This phytoplankton, which consumes carbon dioxide and releases oxygen just like plants, is present in the ocean’s sun-lit surface area – known as the ‘euphotic zone’. Phytoplankton then enters the …

Our Oceans Are Full of Vast Dead Zones Without Oxygen

Scientists have found evidence that far more of the ocean is made of “dead zones” without oxygen than they previously believed. They studied the chemical signatures left by anaerobic bacteria to …

Ocean’s deep-water may be corroding Byron Bay’s coastal ecosystems

On the other side of the Pacific Ocean, in the Californian and Peruvian systems, such upwelling events are accompanied by significant drops in seawater oxygen saturation and pH. Lower pH levels lead …

How ancient oceans of magma may have boosted Earth’s oxygen levels

Shortly after the planet’s formation about 4.5 billion years ago, the mantle somehow became much richer in oxygen than it was originally. That rock began leaking molecules like carbon dioxide and …
