Delegates at this week’s marine science conference in Fremantle take a plastic-free coffee break.
This year's national conference of the Australian Marine Science Association is a plastic-free zone, as marine scientists aim to reduce the environmental burden of throwaway plastic.
New Zealand’s coastline spans a distance greater than from the south pole to the north pole.
New Zealand has one of the world's largest ocean territories, but the marine environment is at risk from climate change, pollution and fishing.
A few days after baby molluscs come out from tiny eggs, they start building their shell layer after layer.
Emily Nunnell/The Conversation NY-BD-CC
Molluscs that have shells - like pipis, clams and oysters - have to build their own shell from scratch. And they keep building it their whole life, using chemicals from the sea and their own bodies.
Eastern rock lobster on sale at Sydney’s fish market. Our preference for a limited variety of seafood drives up prices and threatens the industry’s sustainability.
Australian fishing boats throw away up to half the fish they catch. To make the seafood industry sustainable, we need to eat all the fish that get caught.
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.
The GBR Foundation fills a gap in funding research that might be seen as too much of a risk by other agencies.

Federal Labor has pledged to withdraw the A$443 million given to the Great Barrier Reef Foundation. But the foundation's decisions are led by science, and free of undue influence, its chief scientist says.
Successive governments have seen the Great Barrier Reef not just as a scientific wonder, but as a channel to further economic development.
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.
Sustained ocean warming could greatly reduce catches of fish like these herring photographed off Norway.
Fish are a key food source for millions of people worldwide. But a recent study finds long-term warming over the next 200 years could starve tiny plankton, with impacts that would ripple up food chains.
The Byron Scar, left behind by an undersea landslide. Colours indicate depths.
The ocean floor off Australia's east coast bears the scars of numerous subsea landslides, which have potentially triggered tsunamis over the past several millennia.
Salt flows down rivers to the ocean.
A special combination of rain, rocks and subsea volcanoes makes the sea salty.
The famous “faceless fish”, which garnered worldwide headlines when it was collected by the expedition.
Surveying the bottom of the ocean turns out to be far from easy. But there was something wonderful about seeing animals we have only read about in old books.
Scientists have sequenced the seahorse's genome and found the genes that could explain male pregnancy.
The Balleny Islands off East Antarctica - one of the many stops along the way.
Why spend three months completing a lap of Antarctica (and probably getting seasick along the way)? It's the only way to get vital clues about the remote Southern Ocean and its influence on the planet.
Steven Morgan deploys ABLE robots in a swimming pool to test how well their programs simulate larval behavior.
University of California, Davis
Most ocean species start out as larvae drifting with currents. Using underwater robots, scientists have found that larvae use swimming motions to affect their course and reach suitable places to grow.
School of thought.
Understanding this will boost conservation efforts.
A plague, or just an artefact?
How flawed citation practices can perpetuate scientific ideas even before they've been fully established as true.
Surface oil slick from the Deepwater Horizon oil spill.
Andreas Teske, University of North Carolina Chapel Hill.
Genetic analysis shows that marine bacteria broke down much of the oil from the 2010 Deepwater Horizon spill. These findings could lead to more effective cleanups after future spills.
The next cancer breakthrough could be found in international waters – but who's in charge of the high seas?
The Argo ocean profiling floats are part of a year-round monitoring network for the world’s oceans.
In 1985, when CSIRO's marine labs were launched, a seven-day weather forecast was little better than chance. Now, thanks to advances in our understanding of the oceans, our predictions are far better.
A new research expedition is documenting the deep-sea denizens of the Perth Canyon, such as this flytrap anemone and basket star.
UWA/Schmidt Ocean Institute
The Perth Canyon, off Australia's west coast, is twice the size of the Grand Canyon. But only now, with the help of remote-controlled submarines, are researchers finding out what lives in its depths.
