From the fjords of Norway to the reefs of Bali, Andrew Sullivan’s PhD with IMAS @utas.edu.au is taking him around the world as he investigates how nations are developing policy for a sustainable ocean - and it will help inform future ocean governance. Discover more: tinyurl.com/53xf5svj

1️⃣ "Antarctica might seem a long way away, but really the changes that happen there have consequences for everyone on the planet." — Nerilie Abram, AAD Chief Scientist, ABC Radio 🌊 Rising seas are a planetary impact of global heating. The contribution of melting ice in Antarctica is growing. 🎞️ NASA

2️⃣ But it's much more than sea-level rise. " #Antarctica has long been seen as a remote, unchanging environment. Not any more. The ice-covered continent and the surrounding Southern Ocean are undergoing abrupt and alarming changes" — @aunz.theconversation.com ▶️ theconversation.com/from-sea-ice...

3️⃣ 'Emerging evidence of abrupt changes in the Antarctic environment' is published in nature.com today, led by @climatenerilie.bsky.social with authors from @antarcticsciaus.bsky.social, @arcsaef.bsky.social, AAD, @imas-utas.bsky.social, @ccrc.bsky.social & other key research groups. ▶️ rdcu.be/eBCJA

Deep-sea skates caught accidentally in Southern Ocean fisheries are usually released if they appear unharmed. But their chances of survival after release were unclear until now. IMAS PhD research shows only 1 in 4 survive, and it will improve skate bycatch mmt strategies doi.org/10.1098/rspb...

A Trans-Tasman collaboration between IMAS & @aucklanduni.bsky.social researchers shows Longspined Sea Urchins are a huge threat to NE #NewZealand marine ecosystems. And as the region is at lower latitudes, the impact there could outstrip what we've seen in #Tasmania. Study: doi.org/10.1016/j.je...

How do international Antarctic partnerships benefit the life and work of researchers? IMAS/AAPP researcher Dr Alex Fraser said they are "a fantastic way to broaden collaborative networks, especially for young scientists." ❄️ tinyurl.com/suac8efs @antarctic.bsky.social @utas.edu.au

#Antarctic sea ice is: ⚙️ a global climate engine ☂️ a cooling sunshade 🌀 a pumphouse for currents 🧊 a vast verandah for life ♻️ one of the largest seasonal cycles on Earth 🌬️ highly sensitive to climate variability 🌊 What happens when there's less sea ice? aapp.shorthandstories.com/a-world-with...

Now is not the time to put funding on ice. Australian Antarctic field programs should be ambitious as the rule not the exception, writes Professor Matt King in today's Mercury Newspaper, republished here: tinyurl.com/2zhpbryk @antarcticsciaus.bsky.social @utas.edu.au @deformedearth.bsky.social

Recent record summer lows in Antarctic sea ice are a window into a future warmer climate with more extreme events, but what impacts can we expect? New research clearly shows that faster action on climate change is vital to prevent even more drastic changes in the future: tinyurl.com/Low-summer-s...

Seas the opportunity 🚢 Applications for our 2026 CAPSTAN voyages are now open! This exciting at-sea experience for university students & trainers is all happening aboard CSIRO's research vessel #RVInvestigator, with two voyage opportunities in 2026. Apply now: www.csiro.au/capstan

What can the ancient rocks in the Denman region tell us? Go deeper with Prof Jo Whittaker (IMAS) and Dr Karin Orth (UTAS) to discover what lies beneath, and how ancient rocks hold vital clues about how fast the Denman Glacier is melting ❄️ @utas.edu.au

Unprecedented biodiversity loss and climate collapse are threatening livelihoods across the globe. Ecologists have been critical to uncovering the drivers of biodiversity decline. A new study outlines six actions for ecologists in a time of global environmental crisis: tinyurl.com/5n874r97

Ocean literacy is an understanding of the ocean’s influence on us and our influence on it. It empowers communities to make informed decisions about the ocean. The need for ocean literacy is increasing in Australia and abroad, with researchers calling for a national strategy: tinyurl.com/3cmnvs4v

As part of National Geographic Society & Rolex #PerpetualPlanet Ocean Expeditions, our IMAS ecologist Dr Jane Younger investigated emerging diseases in Antarctic wildlife aboard the R/V Falkor (too) in collaboration with the Schmidt Ocean Institute:🐧 youtu.be/PWV9O8un9P4 More info: bit.ly/3FGjgjX

"There are no images from this part of the Antarctic coastline, this is complete voyage of discovery stuff for us," said IMAS/ACEAS Adjunct Prof Emeritus Craig Johnson. Watch the joy & science of mapping sea floor communities around the Denman Glacier for the very first time youtu.be/gzh5zf73yy4

A little-known ocean current surrounds Antarctica & shields it from warm water further north. Once a steadfast guardian of the icy continent, the Antarctic Slope Current is being transformed by the ice it protects. And it's putting the continent’s last line of defence at risk tinyurl.com/y36mwfje

Our scientists have explored the history, methods & scale of a largely forgotten industry – commercial giant kelp wild harvesting. Harvested in Tasmania from 1964-1973, it would close within a decade. Knowing why provides insights to help future-proof seaweed industries today🌿 tinyurl.com/yx5svfek

A new study has revealed how a large mountain chain buried deep below the East Antarctic ice sheet, grew & partly collapsed more than half a billion years ago. It helps explain why Antarctica’s interior has remained remarkably stable for hundreds of millions of years: tinyurl.com/yka84vfp

Australia’s population of Southern right whales 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 and it could add more than two metres to global sea levels by 2300. New research shows a vast network of lakes and streams under the thick ice sheet plays a far bigger role in Antarctic ice loss than previously thought 🌊 tinyurl.com/ky4de37v
