Last week, the IODP Expedition 403 Postcruise Meeting took place in Svalbard, Norway– a fitting location for an expedition focused on the Fram Strait. Scientists shared findings from the ancient climate, tectonic, and DNA data stored in Exp 403 cores.

35 years ago today Mt Pinatubo caused the largest volcanic eruption since 1912 releasing 50 million tonnes of CO₂ into the atmosphere.
Since then humanity has release 26,000 times more.
Svalbard's mountains were the perfect height to illustrate our @us-sciod.bsky.social Exp403 drill sites. Our deepest hole off the coast was roughly the same depth as these mountains are high, ∼630m. It's amazing to think that some rocks from the valleys the glaciers carved ended up in our cores.
It's out. My latest feature for @science.org, from aboard the RRS Discovery: a deep look at the past, present, and future of AMOC, told through the RAPID program.
AMOC is weakening -- maybe, probably. But it also may be more resilient than some have made it seem.
Ever considered how unfathomably more 1 Trillion is than 1 Billion?
1 Billion seconds are about 31 years. 1 Trillion seconds however are 31,000 years! NYC was covered by glaciers and woolly mammoths were roaming the tundra!
US mid-income net worth is about $200K or in our example here ∼2.3 days!
Studies of the Atlantic's circulation find signs of both weakening and unexpected stability in the face of global warming
Melting permafrost on Svalbard. Our local guide told us this amount of melt used to occur not before mid July.

The Expedition 403 postcruise meeting on Svalbard was a great success. Several days of scientific presentation followed by some time exploring the geology of the fjords. @us-sciod.bsky.social @ecord.bsky.social @anzic.bsky.social
🚨New Exp403 publication, co-led by two fantastic early career scientists, just published the XRF data of Site U1618.

From pole to pole, colorful surface to lightless abyss, the oceans are the planet‘s largest habitat, driver of weather & climate, feed billions, absorbed ∼30% of CO₂ & ∼90% of excess heat from our actions, produce (& use up) 50% of all O₂, support the $3T blue economy...
Happy World #OceansDay.
On Svalbard Exp403 scientists just had the rare chance to observe the sources & processes of ice-rafted debris found in our drill cores. IRD = rocks broken off by glaciers on land, rafted out at sea on icebergs, & dropped on the seafloor. It's an important indicator of past climate dynamics.

The making of the world’s first trillionaire, if sudden—Elon Musk was worth less than $25 billion just six years ago and $150 billion five years ago—has always been inevitable.

It took more than a century to go from first millionaire to first billionaire, and another century to hit $200 billion. Now the world is waiting for its first trillionaire.
