US EditionCoral frozen in time throws lifeline for Great Barrier Reef
- Sydney's Taronga Zoo hosts the world's largest cryobank storing coral cells frozen at-196°C to aid the Great Barrier Reef restoration.
- The cryobank began in 2011 to preserve coral genetic material amid threats like climate-driven bleaching and a halving of live coral since the 1950s.
- Researchers from Taronga and the Australian Institute of Marine Science achieved a world-first on the Great Barrier Reef last year by using thawed frozen coral sperm to fertilize fresh eggs, resulting in healthy coral larvae that were successfully reintroduced to the reef and have shown encouraging growth.
- Justine O'Brien explained that coral's reproductive capabilities are effectively put on hold when frozen, allowing them to maintain their ability to fertilize for many years, even centuries.
- Despite the cryobank's promise, experts warn the Great Barrier Reef faces a closing window due to climate change, requiring wider efforts for coral survival.

U.S. launches deep-sea coral rescue after BP oil spill left ecosystems in ruins
Scientists are restoring coral habitats damaged by the Deepwater Horizon oil spill using underwater robots, lab-grown corals, and Navy divers in one of the most ambitious marine restoration efforts ever attempted.Liz Kimbrough reports for Mongabay.In short:The U.S. is restoring deep-sea coral reefs in the Gulf of Mexico, damaged by the 2010 BP Deepwater Horizon oil spill that released 134 million gallons of oil and devastated nearly 2,000 square…
In a zoo in Sydney, Australia, rows of reservoirs filled with liquid nitrogen form the world's largest warehouse of cryogenicly preserved corals: thousands of billions of cells collected each year on the Great Barrier Reef are expected to allow for...
Ship fuel sulfur content regulations may exacerbate mass coral bleaching events on the Great Barrier Reef
Climate change is increasing the frequency of mass coral bleaching events at Australia’s Great Barrier Reef (GBR), but its sensitivity to changing atmospheric aerosol levels is not well understood. Global shipping fuel sulfur content regulations introduced in 2020 (“FSC05”) significantly reduced ...
In a Sydney zoo in Australia, a row of tanks loaded with liquid nitrogen houses the world’s largest cryogenic coral bank. It is an extraordinary reserve: millions of cells collected annually in the Great Barrier Reef, with the aim of preserving and restoring this threatened ecosystem. This reservoir functions as a kind of frozen Noah’s Ark, created to safeguard marine biodiversity that scientists warn could be the first to extinguish if the adva…
Temperature of 1.5°C in the ocean can expand to 90% of the world's coral reefs In a zoology of Sydney, liquid nitrogen tanks form the world's largest chryogenically preserved coral reserve: billions of cells collected annually from the Great Barrier de Corais to allow regeneration. The reservoir is a frozen Noé Ark for an ecosystem that, according to scientists, can be the first to disappear if climate change is not reversed quickly.
