Australia’s ‘blue economy’ needs a strong basis in marine science.
The triple whammy of the moon’s wobble, sea level rise and more intense storms will bring worse tidal floods into coastal communities in the 2030s. This includes in Australia.
Traditional ecological and cultural wisdom was embraced and valued, enhancing Western scientific knowledge of a beautiful, fragile marine area.

New research involving CRISPR technology has furthered our understanding of corals’ gene functions. Specifically, it has revealed a mechanism underpinning how corals withstand heat stress.
They’re more used to taking visitors to the reefs, but COVID-19 gave tour operators time to help check the condition of the corals. What they found doesn’t bode well.
Restoring the reef represents one of the most significant science and technology challenges in the history of nature conservation.

The findings will help determine the age of whale sharks, protecting the endangered animals into the future.
Corals at Scott Reef in 2012, and at the same site during the 2016 mass bleaching.
The Western Australian coral reefs may not be as well known as the Great Barrier Reef, but they’re just as large and diverse. And they too have been devastated by cyclones and coral bleaching.
Many Caribbean reefs are now dominated by sponges.
Marine sponges are ancient organisms that have survived mass extinctions. Many are more tolerant of climate change and may dominate over corals in future reef systems.
During mass spawning events coral young rise from their parents to ocean surface.

Every year buoyant bundles rise from a spawning coral, giving the impression of an upside-down snowstorm.
How the Great Barrier Reef can be helped to help repair the damaged reef.
Corals on the Great Barrier Reef that are tolerant to warmer waters can be used to help repair other parts of the reef damaged by recent coral bleaching events.
Mobile phones can be used as human tracking devices.
You can learn a lot about the movement of people and animals if you tap into the tracking data from many of today’s mobile phones.
Scientists assess coral deaths in the worst-affected part of the Reef in November 2016.

Two-thirds of the corals in the northern part of the Great Barrier Reef have died on in the reef’s worst-ever bleaching event, according to the latest underwater surveys.

How you tell one whale shark from another? Spots and stripes.
Cartier Island marine reserve is part of a network that covers one-third of Australian waters.

Marine parks need to cover large swathes of ocean, but they also need to cover the right areas if they are to deliver the best conservation. New research off Australia’s northwest suggests how.
Professor Morgan Pratchett surveys bleached corals on Australia’s GBR.

Bleaching has hit a huge swathe of the Great Barrier Reef, with many corals in the reef’s remote northern reaches now expected to die as a result of warm waters linked to this summer’s El Niño.

Banning fishing helps fish, but it also helps reef recover from cyclones, disease, and coral bleaching.
Outbreaks of crown-of-thorns starfish, which eat coral, have been linked to poor water quality.

To fix pollution on the Great Barrier Reef, some farming practices will have to change.
