How ancient plankton point to the resilience of ocean ecosystems The researchers used a cutting-edge approach to predict future ocean conditions by examining the distant past through analyses of microscopic fossils.

🌊In a new study co-led by USF professor @oceanandclimate.bsky.social Patrick Rafter, researchers used forams from the Pliocene to show that warming in the tropical Pacific may not trigger the severe decline in nutrients predicted by earlier models.

Texas is nearing 100 gigawatts of emission-free power (solar, wind, storage, nuclear). EIA reported yesterday that the US will install 50 gigawatts of solar + storage in 2025, 40% of it in Texas. That & much more in today's Grid Roundup. Link in reply.

#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?

😓 These are the folks who provide satellite imagery, maps, and geospatial support to American scientists that operate in polar regions where most satellites don’t reach.

FOR DECADES they have done this, supporting critical work.

They have helped me many times. This is terrible. #WithoutNSF

Studying the role ocean circulation played in shaping past climate and glacial dynamics, I’m absolutely captivated by this new NASA simulation.

Sediment coring: examining a rich and ancient 'layer cake' of #Antarctic climate change

New records from the sea floor near the Denman Glacier and Shackleton Ice Shelf offer crucial insights dating back thousands of years, writes Dr Taryn Noble ⬇️ #DMV @utas.edu.au

Offshore to the west of the Denman Glacier, the Kasten core sediment tubes keep on coming - and this one, retrieved from the seafloor this week, is a keeper #DMV

The first time Sidney Hemming (from @lamontearth.bsky.social) sailed on JOIDES Resolution was in the role of a co-chief scientist. But this is just one part of Sidney’s "big adventure" for IODP Expedition 361. Take a listen at #TalesFromTheDeep in the StoryCorps Archive. 🧪🌊⚒️

These rocks were retrieved from the first dredge, deployed to a water depth of 2700 metres on the steep eastern slope of the Eastern Bruce Rise.

Further dredges are planned, including to features that may be extinct underwater volcanoes.

Please note that our labs now also have windows ☀️
It's sad that the JR got retired, but with all the ship's lab equipment here, the GCR has quickly been transformed to a cutting edge core research facility!

Expedition 398 E&O Officer Susan just published a book on the amazing cores we drilled in and around Santorini.
It's great for anyone (layperson to expert) who wants to learn about these stunning cores.

This paper shows that every dollar spent on improving hurricane forecasts pays for itself many times over in reduced damages: www.nber.org/papers/w32548

Cutting funding for weather forecasting does not save money - it costs billions in addition to putting lives at risk

While the U.S. undermines researchers, China can shift global economy The Trump administration's proposed cuts to research could shift the balance of global economic power to China.

The U.S. passes the torch of scientific dominance to China.

The National Academies released the Decadal Survey "Forecasting the Ocean" stating: "U.S. investment in ocean science, engineering, and technology is not keeping pace with growing societal needs, even as U.S. competitors are increasing investments in ocean science and advancing their capacities"
