‘LarvalBot’ underwater drone will reseed coral reefs damaged by climate change

 

Since August 2018, the Great Barrier Reef in the ocean off Australia has had a special protector — an autonomous underwater drone called RangerBot that has monitored the status of the reef and protected the corals from the predatory crown-of-thorns starfish. But now researchers at Queensland University of Technology (QUT), Australia have announced that the RangerBot has a new mission: it is to be rechristened “LarvalBot” and will be repurposed to spread coral babies.

Scientists have collected hundreds of millions of coral spawn from the surviving corals of the Great Barrier Reef which have not yet succumbed to coral bleaching. These spawn are then reared into baby corals in special floating enclosures, and once they have grown large enough to survive on their own, they are delivered by the LarvalBot to a designated location in the reef. If necessary, many coral larvae can be distributed at once in a “larval cloud” that can blanket an entire damaged area of a reef. This technique is called larval restoration and may be reef’s best hope for the future.

Ocean life threatened by mass extinction

The combined effects of climate change, over-exploitation, pollution and habitat loss will cause the mass extinction. 

Ocean life is at an imminent risk of the worst spate of extinctions in millions of years due to threats such as climate change and over-fishing, according to a study led by the International Programme on the State of the Ocean (IPSO).

New research suggests that coral reefs located in marine reserves can recover from the impacts of global warming.

A study by the University of Exeter provides the first evidence that coral reefs can recover from the devastating effects of climate change. Published Jan. 11, 2010 in the journal PLoS ONE, the research shows for the first time that coral reefs located in marine reserves can recover from the impacts of global warming.

Scientists are developing a robotic octopus that will be able to search the seabed with the same extraordinary dexterity as the real eight-legged cephalopod. With no solid skeleton, the robot would be the world’s first entirely soft robot, say researchers.
