GGRiP Bristol has begun! @alexauderset.bsky.social gave a fantastic keynote on nitrogen isotopes as a tool in paleoceanography!

Ever wanted to see how a coral skeleton grows? In this paper (led by: @jtrendbio.bsky.social) www.sciencedirect.com/science/arti... we use Live CT, a method of scanning live organisms using microCT, to visualise how the skeleton grew over about one month.

I will forever be haunted by this footage.

Trawling has only been filmed underwater a few times in documentary history, and never with such clarity.

What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives.

Nice summary thread too!

Change in iceberg calving behavior preceded North Sea ice shelf disintegration during the last deglaciation - Nature Communications Massive tabular icebergs broke off of the UK during the last ice age. The widespread break-up of the ice shelves which produced these giant icebergs can be traced to around 18,000 years ago, and likel...

Icebergs? The size of a city? 90 miles from the UK? Must be a joke, right?

No! Our new paper in @natcomms.nature.com shows massive tabular icebergs broke off the UK in the last ice age before the UK’s ice shelves disintegrated from climate warming.

How tiny foraminifera can play a massive role in understanding past climates Foraminifera comprise a group of heterotrophic zooplankton, which inhabit all depths within the world's oceans from the sunlit surface ocean to the depths of the abyssal plains. Many species build a ....

Department for Education confirms launch of natural history GCSE Campaigners have been calling for the qualification for years but plan stalled despite a curriculum being drawn up

This is great, I would have loved to take this! I hope it will involve the whole Earth system, not just ecology. If 16 yr olds leave with the idea that it's all connected in one beautiful complex web – biosphere, atmosphere, oceans, climate – it will have done a great service.

Like morphometrics, micro-CT scanning, and morphological evolution? Then please consider applying for our 18 month postdoc position at the university of Southampton! Details here: www.jobs.ac.uk/job/DMF402/r...

I'm always amazed the anyone-can-edit free-for-all doesn't descend into rubbish, it's a modern marvel!

I agree! It's one of the best things about the internet, and arguably editing articles that you know about is the most impactful science communication you could do (or at least has the widest reach)

Oh nooooo! Just leave it alone!

Nice one Mike!

So this is where everyone is! 👋 Hello, I'm a final-year PhD student at @unisouthampton.bsky.social and @bas.ac.uk investigating the provenance of ice rafted debris in W #Antarctic marine sediments with #geochemistry and #geochronology. More on my website! 🇦🇶🏔️🌎
