Earth scientists are on the skilled occupation list for immigration even as universities cut back in this area. The problem lies with a funding model that offers no incentive to lift graduate numbers.

Oceanographer Robert D. Ballard, who is best known for finding the wreck of Titanic, has written a memoir recounting his biggest discoveries and calling for more ocean exploration.
When sea sediment melts inside the Earth, it helps tectonic plates slide over one another smoothly.

Aftershocks of a major earthquake can continue for years or even decades.
A copper mine in Phalaborwa, South Africa. The African continent is home to vast mineral resources.
It seems the production of Earth science knowledge in Africa is simply not progressing, despite the world’s interest in (and exploitation of) the continent’s mineral wealth.

The science-fiction scenario of an engineered planet is already here.
Ancient fatty molecules, once believed to be traces of some of the first animals to live on Earth, may have been produced by algae instead.
It’s one of the largest funding cuts to any university course, and will leave Australia ill-equipped to deal with the environmental challenges of the future.

Born on July 30, 1920, geologist and cartographer Tharp changed scientific thinking about what lay at the bottom of the ocean – not a featureless flat, but rugged and varied terrain.

A network of sensitive instruments in schools around Australia is recording the eerie silence of the coronavirus pandemic — and tiny earthquakes that would otherwise be undetectable.
New research suggests that Earth’s oxygenation didn’t require difficult and complex evolutionary leaps forward.

Oxygen flooded the atmosphere for the first time and then … nothing. Or so we thought.
Earth is really ancient, and humans have only been around for a tiny part of that time.
All the buildings and the cars and the restaurants, and the phones and even everything that’s inside of you… it all started with an exploding star, billions of years ago.
Droplets rising from the Champagne vent on the ocean floor in the Mariana Islands. Fluids venting from the site contain dissolved carbon dioxide.

Thousands of years ago, carbon gases trapped on the seafloor escaped, causing drastic warming that helped end the last ice age. A scientist says climate change could cause this process to repeat.
The research vessel must dodge dangerous icebergs as it drills for sediment core samples.
A paleooceanographer describes her ninth sea expedition, this time retrieving cylindrical ‘cores’ of the sediment and rock that’s as much as two miles down at the ocean floor.
An eruption of Anak Krakatau caused an underwater landslide and tsunami that struck Java and Sumatra.

Research into volcanic activity in the waters off Indonesia shows how active this region is and how destructive landslide-caused tsunamis can be.
It’s core to life on Earth.
The Earth’s core is cooling down, and one day it will be completely solid – when that happens, Earth might look a lot like Mars.

Gravity, not magma, is forcing Etna to move, increasing the chances of collapse.
The scientific drilling ship JOIDES Resolution arrives in Honolulu after successful sea trials and testing of scientific and drilling equipment.
The ocean floor holds unique information about Earth’s history. Scientific ocean drilling, which started 50 years ago, has yielded insights into climate change, geohazards and the key conditions for life.

How do the narrow ribbons of sand that line the Atlantic and Gulf coasts withstand the force of hurricanes? The answer lies in their shape-shifting abilities.
