A large research vessel - black and white and orange - floats in the water with ropes holding it to the building dock.

A group of individuals in matching white hard hats pose for a photo on the side of the large research vessel.

Oregon State University, with support from the National Science Foundation (NSF), is leading the design and construction of the next generation of #research vessels - ships that serve as floating laboratories for ocean-going scientists - to advance coastal #science.

Check out R/V Taani's progress!

Glad to have Demian on our team!

Oregon’s record low snowpack is not likely to recover, scientists say Scientists say it’s unlikely Oregon’s record low snowpack will recover before the end of winter.

“We know that the winters in the coming decades are going to be much more like this... look at how impactful these conditions are to us, because we know we’re going to expect them more in the future.” - Larry O'Neill, Oregon's state climatologist

Come work with us! Thanks for sharing, Dawn!

Spotlight on: The Disasters in Divided Societies lab with Laura Peters in CEOAS | OSU Today Laura Peters is an assistant professor of geography in the College of Earth, Ocean, and Atmospheric Sciences.

"For a lab focusing on disasters, we end up engaging with some of the most powerful stories of hope and creativity."

#CEOAS geographer Laura Peters asks how disaster risk can be reduced in places affected by conflict, displacement or deep division: today.oregonstate.edu/all-stories/...

A Pacific Northwest girl ‘raised by the ocean’ grows up to make notable contributions to worldwide ocean health “Standing at the edge of the world, in a place I only knew from photos and documentaries, I can’t imagine a greater thrill than this,” she wrote in one account. “The thrill of seeking to know the ocea...

SWAIS2C — Sensitivity of the West #Antarctic Ice Sheet to 2°C — seeks critical geological records from the sediment deep below the Ross Ice Shelf to determine how much the #ice melted during the past. Because to prepare for the future, we need to look back.

#CEOAS #Science #Climate #Collaboration

Drilling a 200m sediment core from the bedrock beneath 500m of Antarctic ice is a complex process, so we've broken it down step-by-step in this explainer. From melting snow in our flubbers through to filling our core barrels, what we're attempting 700km from the nearest base is no mean feat!

"Dr. Pettit and others expect the shelf to break apart entirely in the next few years, becoming a mélange of giant icebergs. Once that happens, the #ice upstream could start moving quickly to fill the void, Dr. Pettit said. “They are connected in ways that we don’t fully understand"

New Lessons from Old Ice: How We Understand Past (and Future) Heating - Eos Fragments of blue ice up to 6 million years old—the oldest ever found—offer key insights into Earth’s warming cycles. Researchers are using these ancient data to refine models of our future climate.

“Ice cores are like time machines that let scientists take a look at what our planet was like in the past," said Sarah Shackleton, lead researcher and scientist at @whoi.edu.

A team of #NSF Center for Oldest Ice Exploration #COLDEX scientists recently found 6 million year old ice in Antarctica. That's old ice!

Why Hasn’t Wave Energy Gotten Its Sea Legs Yet? It’s hard to convert energy from the ocean into electricity, thanks to a tough regulatory environment and, well, the ocean.

PacWave is an 80-million dollar facility that lets developers "plug and play," testing #renewable energy technologies that might someday capture the strength of the ocean.

@scifri.bsky.social has the latest on harnessing wave #power into energy: www.sciencefriday.com/segments/wav...

"You want big waves, you want consistency in big waves. And Oregon really has this in droves...all of these conditions come together to produce one of the areas of the world with the highest #wave energy potential."

One of the largest wave #energy projects, PacWave, is located off Oregon's coast.
