Is global warming causing marine diseases to spread?

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.

Avoiding Medusa’s gaze: what sharks can tell us about a rare human disease

Some things that develop as normal in elephant sharks and other marine life can mimic things we see in human disease. That makes these 'mutants' ideal for study to find out why things go wrong in humans.

The oceans are changing too fast for marine life to keep up

Over the past five years we've seen a significant increase in research on ocean acidification and warming seas, and their effect on marine life. Overall, unfortunately, the news is not good.
This common lionfish (Pterois volitans) was sighted more than 200km further south than expected down the NSW coast by 14-year-old scuba diver Georgia Poyner. It’s one of almost 40 verified observations she has submitted to Redmap. Redmap/Georgia Poyner

How you can help scientists track how marine life reacts to climate change

We know the warming seas are forcing some marine life to new waters, but we don't know much about how fast and how far they are moving. But now you can help scientists find the answers with Redmap.
The Great Southern Reef is unique, beautiful and contributes significantly to Australia’s culture and economy. However, few of us realise the magnitude and value of this gem right at our doorstep. T. Wernberg 2002

Australia’s ‘other’ reef is worth more than $10 billion a year - but have you heard of it?

The Great Southern Reef covers 71,000 square km and contributes more than A$10 billion to Australia's economy each year.

Rising seas could drown turtle eggs: new research

Immersion in seawater kills sea turtle eggs, suggesting that sea turtles are increasingly at risk from rising seas, according to research published today in Royal Society Open Science.

The march of the king crabs: a warning from Antarctica

Hundreds of meters below the surface of the freezing ocean surrounding Antarctica, the seafloor is teeming with life. The animals living there have no idea that an army is on the brink of invading their tranquil environment.
The cycles of nutrients into the oceans following the building of mountains may have been a prime driver of evolutionary change. John Long, Flinders University

Plate tectonics may have driven the evolution of life on Earth

The rise and fall of the essential elements for life could have influenced the way life evolved over many millions of years.

Following Nemo: marine life is heading south

As warmer seas move further south, tropical wildlife is going with them, giving us a dramatic insight into how global warming is changing our oceans.
