Scientist at work: I’m a geologist who’s dived dozens of times to explore submarine volcanoes

When you study volcanoes at mid-ocean ridges, doing fieldwork means becoming an aquanaut – diving thousands of feet to the ocean floor in the submersible Alvin, trading tight quarters for amazing views.

Curious Kids: how do mountains form?

When I was little, geologists worked out Earth's surface was made of pieces, like a giant puzzle. Those pieces, called “tectonic plates”, move and bump into each other and mountains form.

How Eurasia’s Tianshan mountains set a stage that changed the world

Setting the scene for ancient Silk Road trading and now China's Belt and Road initiative, the Tianshan has changed humanity. Geological evidence shows us how this incredible mountain range formed.

How rare minerals form when meteorites slam into Earth

A meteorite hitting Earth at many kilometres per second puts 'ground zero' target rocks under immense pressure. A shock wave faster than the speed of sound can result – and new materials created.

Scientists have been drilling into the ocean floor for 50 years – here’s what they’ve found so far

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.

Would an eruption in Melbourne really match Hawaii’s volcanoes? Here’s the evidence

Melbourne lies at the eastern end of a volcanic province, but when's it going to blow? Understanding the geology of Melbourne and comparing it to Hawaii is really helpful in calculating risk.
Successive governments have seen the Great Barrier Reef not just as a scientific wonder, but as a channel to further economic development. Superjoseph/

Politicised science on the Great Barrier Reef? It’s been that way for more than a century

The $444 million awarded to the Great Barrier Reef Foundation has been criticised as a politically calculated move. But governments have been asking what the reef can do for them ever since colonial times.
