Australia’s pop'n of #Southernrightwhales has grown substantially since the late 1970s when they began to recover from whaling. But a new study reveals troubling signs that could mark a turning point in the population’s recovery: tinyurl.com/4rd9uu2z

There’s a hidden threat beneath Antarctica’s ice sheet & it could add over 2m to global sea levels by 2300. New research shows subglacial meltwater plays a far bigger role in ice loss than previously thought & it urgently needs considering in modelling: theconversation.com/antarcti…

Antarctica’s hidden threat: meltwater under the ice sheet amplifies sea-level rise

A new study found parts of Antartica could pass a tipping point for mass ice sheet losses as soon as 2050 – pushing sea levels 2 metres higher by 2300 than currently predicted.

When not working with her horses, Dr Linda Armbrecht (@IMASUTAS) is pioneering techniques to extract ancient DNA from Antarctic seafloor sediments, unlocking secrets from up to a million years in the past.

Huge congrats to Linda Armbrecht who's received an @Science_Academy Honorific Award, the Dorothy Hill Medal, for her detective work using ancient DNA preserved in the seafloor in polar regions to discover what organisms once lived in our oceans. Dive in: vimeo.com/1069109404

Oceans are at the forefront of many new climate-related projects. But a new study shows the speed they're being developed & expanded is outpacing the ability to govern them effectively - & manage their potential impacts on marine ecosystems & communities tinyurl.com/mtdk9zdd

🎣 Commercial overfishing has helped to manage the numbers of long-spined sea urchins off the Tasmanian coast say @UTAS_ @CSIRO @IMASUTAS buff.ly/bp2ZENL

The first Kasten core deployment has extracted a tube of mud from the #Antarctic seafloor. Once in the lab, the sampling begins for traces of ancient eDNA (@AusAntarctic) and porewater, and measuring for thermal conductivity. #DMV @IMASUTAS | @UTAS_ 📷: Katharina Hochmuth

In our warming oceans, marine species are moving into new areas and ‘re-engineering’ or often destroying those ecosystems, but scientists say the paradox of overfishing sustainably can help: tinyurl.com/3jvsh4hw

Adding natural alkaline substances to seawater can boost the ocean’s ability to absorb CO2. But IMAS scientists warn there may be processes in the ocean system that alter the efficiency of ocean alkalinity enhancement. Story: tinyurl.com/58fzydeb Study: doi.org/10.1038/s41561-025-0…

A new IMAS study out today reports a recent upward trend in the relative abundance of Maugean skate in #MacquarieHarbour. It’s a potential sign the wild population of this endangered species has improved, w research catch rates at levels last seen in 2014 tinyurl.com/bdfbjave
