Scientists have developed a scalable “holdfast-graft” method to reseed Tasmania’s lost giant kelp forests. By binding hatchery kelp to other seaweed stubs, divers achieved 40× higher survival. Within a year, the grafted kelp began reproducing—kick-starting self-sustaining forests. #GreatSouthernReef

In addition to its striking appearance, what makes the longsnout boarfish stand out is its unusual feeding habits.
Along with the worms you’d expect from a bottom-dwelling predator, it also preys on brittle stars.. a rare choice among fishes.

Meet the humble ascidian, a.k.a. sea squirt. New research suggests one species could alter the role of reefs in a warming ocean. At Solitary Islands they increased 4x. The microbes within produce N₂O, a greenhouse gas about 300x more potent than carbon dioxide.

For Dominic Buyers, every dive begins long before he enters the water. From tides to topographical maps, preparation shapes every image he creates. He prefers diving between slack high and outgoing tide, when visibility improves and marine life appears more active.

The Hippolyte Rocks, off the Tasman Peninsula, is challenging to access due to rough weather, but when conditions align, the visibility, colours, and marine life are unmatched.

Shaun de Bruyn is the CEO of the Tourism Industry Council of SA and was part of the GSR HAB delegation to Canberra.

“From a scientific perspective, the GSR which supports $11.5 billion in jobs, seafood and tourism, deserves long-term funding to track ecosystem change on a level similar to the GBR”

New research published in Science warns that ocean-based climate interventions are moving faster than our ability to regulate, monitor, and evaluate them. One of their key messages is that monitoring must be comprehensive & connected. theconversation.com/marine-clima...

Footage captured yesterday at Ardrossan, Yorke Peninsula, reveals more underwater impacts of SA's Harmful Algal Bloom.

With neon green water, the seabed was littered with dead and dying animals. There were also hundreds, if not thousands, of garfish on the seabed, some still alive.

GSRRP Scientists have contacted the Federal Government, urging investment & offering to meet. Neither the funding request nor the meeting was acknowledged. Without a proper national monitoring program, our ability to prepare for, understand & respond to future marine heatwaves is extremely limited.
