#iodp — Public Fediverse posts

The Hawaiian Drowned #Reefs expedition was one of the coolest things #IODP did before the program ended. Now all the site reports and core descriptions are online.
(And I just need to get around to reading them)

... still sad I didn't get to join it.

Applications are open for the 2nd MagellanPlus 21st Century Drilling Workshop.
Come and form a team of geoscientists doing core description, #biostratigraphy, #geochemistry, and physical properties, trying to tease our understanding of the #Miocene ocean and climate.
Between 3 and 12 Nov 2024 at the #IODP Bremen Core Repository.

Learned today:
Cement -making, which involves high heat, incurs 9% of the annual global CO2 emissions.
Roman #cement endured 2000 years, and counting.
"Ours" lasts merely 50-150 years.
Why is that?
Ours crumbles because little fissures are widened by rain water.
The Roman mix contains lotsa tiny calcium lumps. When fissures occur and rain enters them, it dissolves the calcium crumbs and this "dough" smears across the gaps. Case closed.

Heard in a curious podcast episode by a Noam Hassenfeld.

Also learned: when scientists drilled for sediment cores in 2022/2023 around Santorini and the submarine #volcano , the drill got stuck often, and 3 times, they had to use explosives to get it free. One reason: a Roman cement structure on the sea floor !
Thomas Ronge, cli-sci on this #IODP expedition, posted it yesterday on Bluesky.

Drillig deep into the mantle has been on the wish list of #ScientificOceanDrilling since #ProjectMohole - #IODP #EXP399 achieved an incredible record with 1268m on TheJR last year - read more about it here: https://science.org/doi/10.1126/science.adp1058 #KeepDrilling

"Searching for the future at the bottom of the sea" - nice article on #IODP #EXP403 with TheJR by Corriere

Weather can't seem to make up its mind in Bremerhaven ( @awi ) for the #IODP / #ICDP meeting to discuss the future of scientific drilling and learn of the cool works that has been done on the cores already collected.

We really need to talk more about what's going on with #IODP. After more than 60 years of (near) continuous activity, the program is now in its most precarious and fractured state.
There is a new program (#IODP3) in the works, but it's a much smaller dream.

https://www.nytimes.com/2024/08/26/science/drilling-ship-science-joides-resolution.html

I'm still trying to process this one (because math, hard), but it does present an interesting framework to explain the preservation of #OrganicMatter in #sediment and when carbon really leaves Earth's superficial #CarbonCycle.

Yet another study made possible by #IODP, that we could not do again without.

My girlie chart with 490ky years of #Milankovic cycles, CO2, sea level, and the top line is d18O of a sediment core from within the #ColdBlob, see map. I think, it records AMOC shutdowns in the past.

Would be intriguing to know why it shut down. Eg, 427ka, "just" before the interglacial MIS11.
And why it not shut down during that very long interglacial which was ~as warm as the Holocene,
and had an ice-free West #Greenland (with a leaf found just 2 years ago at rock-bottom of an ice core from there),

and why AMOC instead collapsed in the middle of the following #iceage.

The very long interglacial MIS11 with its ice-free West Greenland and stable AMOC throughout tells me that the amount of freshwater input from melting ice on its own isn't the trigger for a collapse. But instead, the speed at which freshwater is added: very slowly like during #MIS11 won't do it.

Also intriguing: why the stuttering motor during the last glacial before the #Holocene?

#d18O from sediment cores at other locations strictly follow the ups and downs of #sealevel and #CO2. This one site #IODP #U1308 is exceptional.

#WeekendReading: Prine et al. looks as the dolomite in the #Maldives drift bodies drilled by #IODP #exp359... I wanted to do that for years but never got around to it - happy someone finally did.

@sewblue
These scientific drilling operations is where we get most of our knowladge about past ocean and climate (for the last ~100Myr).

What's the story with #theJR?
#IODP now has three operations: the European-led Mission Specific Platform, targeting mostly shallow water and continental margins. The Japanese-operated Chikyu Hakken for sensitive pressure drilling, that does not venture far from the Japanese EEZ.
And there is the US-operated JR that does everything else everyehre else.
