Over 1000 Coral Reefs Mapped in Northern Australia
and they become much clearer. It allows us to peek deeper into the water column than we could in one image.”It took 700 hours just to digitize the reefs and assign classifications to them.Dr Lawrey said the work revealed that northern Australia had a similar quantity of reefs as the Great Barrier Reef, albeit many of the reefs were much smaller.Previously, most of the northern Australian coastline was unsurveyed. The best mapping of northern Australia could be found in the marine charts which did not distinguish between coral reefs and rocky reefs as they were simply designed to warn vessels
Subsea Technology Helps Coral Larvae Find Home
This week, researchers at Australia’s Southern Cross University and CSIRO gave hope that millions of coral larvae on the Great Barrier Reef can help replenish degraded reefs thanks to the development of a “larval seedbox.”Results from the first trial have found coral settlement to be up to 56 times higher across thousands of square meters of reef. Large scale operation is achievable as tens of millions of larvae can be collected during the annual mass coral spawning that occurs each November in the Great Barrier Reef.The development comes as global warming is crossing dangerous
Larval Seedbox Boosts Coral Restoration
Millions of coral larvae on the Great Barrier Reef have an increased chance of replenishing degraded reefs thanks to the ‘larval seedbox’ - a coral restoration technology developed by CSIRO, Australia’s national science agency, with Southern Cross University.Results from the first trial of larval seedboxes have found coral settlement to be up to 56 times higher across thousands of square meters of reef.The trial was conducted at Lizard Island in 2024 and shows strong promise for use of seedboxes in scaling up coral restoration.Dr Christopher Doropoulos, Senior Research Scientist at
Scientists Explore Assisted Evolution to Help Coral Reefs
of approaches that involve active intervention to accelerate the rate of naturally occurring evolutionary processes. These approaches aim to enhance certain attributes such as temperature tolerance, growth, or reproduction.The aim is to enhance the spread of naturally warm-adapted genes across the Great Barrier Reef to buffer populations on cooler reefs against continued warming and bleaching
Drones Reveal Extreme Coral Mortality After Bleaching
New research has revealed coral mortality rates of 92% after last year’s bleaching event at Lizard Island on Australia’s Great Barrier Reef, marking one of the highest coral mortality rates ever documented globally.The team assessed the impact of the Fourth Global Coral Bleaching Event, declared by the National Oceanic and Atmospheric Administration (NOAA) in April 2024, which caused extensive bleaching and mortality across the reef system.Their findings, published in Coral Reefs, used high-resolution drone imagery to map coral bleaching in March 2024, returning in June to assess survival

The Future of Coral Reef Protection
fish abundance, diversity, length and biomass.By centralizing all this data in real time, they hope to generate predictive models that will help conservation efforts, enabling early intervention.Citizen scientists are also helping with reef conservation. Volunteers are helping with surveys of the Great Barrier Reef led by Citizens of the Reef. A census conducted late last year generated over 43,000 images. Using citizen observers and AI to review the images can achieve nearly the same level of accuracy as expert analysis.“Anyone with a few minutes to spare can help,” said Nicole Senn, head
Integrated Data System for Coral Reefs Enables AI Analysis
