The #DMV is nearing its end 🌊
@AntarcticSciAus Science Lead Prof. Delphine Lannuzel explains why this sort of scientific collaboration in the field is "super important."

Fantastic to be a part of this @FRDCAustralia project using BRUVs and AI to provide fisheries independent data to improve stock assessments model.

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…

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

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

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

🌊 "As an oceanographer, I’m excited about the prospect of getting ocean, ice and climate data from a region where few observations have been collected.
The only way to get information like this is to be there."

We’ve teamed up with @IMASUTAS to explore how waste from urchin harvesting could be repurposed as a soil booster for agriculture.

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

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

Christmas might be over, but the gifts keep coming for the @AntarcticSciAus geo team! 🪨🎁
Today @IMASUTAS Dr Jodi Fox took delivery of new rock samples from Gaussberg - East Antarctica’s only exposed volcano 🌋 (even geophysicists were excited, right @Ina_Else 😉) ⚒️🧪
