“Large, vertebrate, carnivorous micro-endemics are incredibly rare all around the world. In Tasmania, we are very lucky to have had three: the Tasmanian devil, the Maugean skate and the thylacine.” — David Moreno, @imas-utas.bsky.social

These minerals are currently sitting atop the sea floor, waiting to be scooped up and processed. Through #NOAA’s mapping tech and licensing abilities, we are helping industry leaders find, collect and bring back these minerals to benefit the #USA & domestic manufacturing.

Following a massive die-off, two major #salmon companies operating 14 fish farms in the D’Entrecasteaux Channel in southern Tasmania have been ordered to prevent its pollution by dead fish.

Fascinating result of an organisation not really caring much about women & children so not even noticing their expressions or how absurd this scenario seems. Because they’re just generic prop people for the man to explain things to.
A startled-looking woman in a cardie and a ponytail, a marketer’s idea of a generic mum, seems to have been accosted in the fridge aisle of a supermarket by Liberal Party leader & nuclear disposal enthusiast Peter Dutton who is gesturing at her with a blank expression and looks to be explaining something. The position of his hands suggests he is demonstrating juggling one orange. The top of his head is bouncing fluorescent light. The people and the ceiling are white. A small child is holding the handle of the woman’s shopping trolley, sporting a thousand-kilometre straight-ahead stare. He is showing no interest in the bouncing-light man. The woman has not put her handbag into the shopping trolley as is customary, suggesting she may need it to bribe somebody to leave her alone, before she gets to the frozen section.

🌊 "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."

Yesterday we did it! Brave people ('kayaktivists', to borrow a US term) successfully stopped coal ship from the port of Newcastle - and 170 of these legends were arrested. Today we are supporting those who face court on this day. It's not over – join us in Canberra for action this week, 26-28th!
