What scientists first thought was an ancient species that had survived undiscovered for many millions of years, turns out to be part of something equally mysterious.
Climate change isn’t the only thing making sea levels higher and cyclones more intense.
Researchers have long used such techniques to learn about currents and tides.
Marine sediments provide evidence of climate variability in South Africa going back 270,000 years. These changes correspond with changes in the archaeological record of the country.
Infectious diseases are a normal part of ocean ecosystems, just as they are on land. But climate change is altering the oceans in ways that could make marine diseases spread farther and faster.
The open oceans are the world’s “wild west”, falling outside any nation’s jurisdiction. UN negotiations are aiming to draft new laws for the high seas.
The next cancer breakthrough could be found in international waters – but who’s in charge of the high seas?
From time-shifting earthquakes to bizarre creatures, the crushing depths of the hadal zone are another world.
Shellfish will have more brittle shells as oceans get more acidic – making them more vulnerable to predators. New research gives a fascinating glimpse into how they will adapt.
The way ice sheets respond to global warming may be more predictable than previously thought
The Great Barrier Reef might get all the attention, but what about our western coral reefs? Warmer waters and human impacts mean these reefs are in trouble.
The 2011 Japan tsunami illustrates how more marine creatures are crossing the oceans than ever before - and not all of them are friendly travellers.
Africa has some wonderful beaches. A serious traveller should visit at least one of them once in a lifetime.
Many corals can’t make it through the bleaching events caused by warming ocean waters. But some can – and scientists are trying to learn more about the sources of their resilience.
There are more bacteria in the ocean than stars in the known universe. New genetic techniques are letting us use microbes as early warning systems for oceans in trouble from pollution and other stresses.
Enhanced data collection capabilities will ensure that information collected from the coastline will be seamless.
Mining the deep oceans for minerals may soon become a reality, but the risks involved are many. So who is able to regulate this emerging industry?
The dust storm that turned Sydney red in 2009 triggered plankton blooms in the Tasman Sea, demonstrating how we might fertilise the ocean to take up more carbon dioxide.
One of the Australian government’s new research priorities is “environmental change”. But can be hard to know how to tackle such huge and interlinked issues as climate change and species extinctions.
