Hi Bluesky!

I'm a Lecturer in Marine Geosciences at the University of Barcelona. I currently teach the courses "marine Geology" and “Marine depositional environments and processes” in the BSc Marine Sciences and BSc Geology degrees.

🌊 Beneath the ocean surface, there's a hidden world of trenches, seamounts, and even volcanoes! So, how deep is the ocean on average?

🐚What can seashells tell us?

A new article in The Conversation co-authored by Tom Frazer, professor and dean of the College of Marine Science, explores how seashells can act as a historical record of seagrass health.

🌊 Ocean warming threatens the viability of 60% of Antarctic ice shelves

If global temps stay <2 °C, nearly all 64 ice shelves survive by 2300. But above ~4.5 °C, ocean melt causes 38 shelves to collapse by 2300, risking up to 10 m sea level rise.

Ocean warming threatens the viability of 60% of Antarctic ice shelves - Nature
The viability of Antarctic ice shelves under low rates and high rates of global warming is modelled to estimate when it will become unfeasible for the ice shelves to maintain their present-day shape.

Up to 59% of Antarctic ice shelves may be at risk of disappearing under high-emission scenarios by 2300, according to an analysis of the effect of ocean warming in Nature. This could result in up to 10 m of global sea-level rise. go.nature.com/47Ag4k1 🌊 🧪

New study identifies a critical threshold: 7.9% annual bleaching triggers major reef degradation.
Even best-case climate scenarios show widespread losses by 2100.

The way light reflects and refracts from water, esp. near the coast, has a lot to do with the sediment ( and other) particles suspended in them. What I didn't realize was that the waves can orient the particles, and thus how light behaves. 🧪🌊

🌊 Melting Arctic ice is opening the Arctic Sea Route, reshaping global trade, but at a cost.

A new study finds ASR use could raise global shipping emissions by 8.2% by 2100.

Current policies fall short…only a net-zero strategy can curb Arctic impacts.
