The marine biodiversity impact of the Late Miocene Mediterranean salinity crisis
Massive salt accumulations, or salt giants, have formed in highly restricted marine basins throughout geological history, but their impact on biodiversity has been only patchily studied. The salt gian...

Brachiopods once were the dominant invert group, but after the Permian-Triassic extinction, bivalves began to run the show. There are 100s of brachs alive, but >20,000 species of bivalves by some counts! Brachs to me are the elves of invert paleo. A noble race reminding us of a better age. (302)

Climate and ice sheet processes in Antarctica increasingly reflect those observed earlier in Greenland. Applying process insights from Greenland can improve projections of future Antarctic ice and climate behaviour.

🌊 Ocean stratification has increased since the 1960s, rising 0.8%/decade due to warming, with projections of up to 2.9%/decade by 2100 depending on emissions

Ocean stratification in a warming climate - Nature Reviews Earth & Environment
Ocean stratification — density-related layering of seawater — influences oceanographic and climatic processes. This Review outlines observed and projected changes in stratification, noting a 0.8% dec−1 increase in 0–2,000 m stratification from 1960–2024, and a further 1.4% dec−1 increase by 2100 under SSP2-4.5.

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

That moment when you spot a deep-sea cutie 😍
Deep-sea hatchetfishes cleverly camouflage themselves in the dark depths of the ocean with light-producing organs along their bellies. This allows them to match the daylight filtering from surface waters above and hide from predators lurking below.
