Climate scientist and geochemist @UnivofStAndrews | CO2 & ocean circulation past & present | Social & Environmental justicehttps://bsky.app/profile/mudwaterclimate.bsky.socialhttps://bsky.app/profile/mudwaterclimate.bsky.social/post/3mlbvrbo4zk2uWas a real pleasure speaking to @elisecutts.bsky.social for Science on the beautiful new CO2 results over the MPT from Beyond EPICA presented by Florian Krauss at EGU. (And also nice to see them line up nicely with our CO2 reconstruction from boron!)

Lovely to have you over here. I tend to post on how past climates help us understand where we’re heading, including changes in ocean circulation, acidity, sea level, and CO2, as shown below. 🌊⚒️🧪🐚📈 [contains quote post or other embedded content]14 Nov 2024 06:20 +0000at://did:plc:bph42aa6ki7oq6q2puaeaecb/app.bsky.feed.post/3lav7syh3v22dhttps://bsky.app/profile/mudwaterclimate.bsky.social/post/3l7dhgvhuck2sNice nerdy contribution for geochemistry peeps - we use a new sequential leaching method to get accurate carbonate d11B from mixed matrix samples, demonstrated by getting true d11B from a coral, even when we filled the sample with clay! 🧪🌊⚒️ https://agupubs.onlinelibrary.wiley.com/doi/epdf/10.1029/2023PA00465825 Oct 2024 11:23 +0000at://did:plc:bph42aa6ki7oq6q2puaeaecb/app.bsky.feed.post/3l7dhgvhuck2shttps://bsky.app/profile/mudwaterclimate.bsky.social/post/3l66yz5pyyr2oAbsolute scenes in Cellardyke!10 Oct 2024 23:29 +0000at://did:plc:bph42aa6ki7oq6q2puaeaecb/app.bsky.feed.post/3l66yz5pyyr2o
