Nerdy details: we show using of (δ¹³C) and (δ¹⁸O) that **ONLY** Miliolida benthic foraminifera (including , , & - pictures attached) found **ONLY** in sediments proximal to methane hydrates (site U1446 is in the NW Bay of Bengal) contain wildly negative δ¹³C signatures characteristics associated with methane dynamics in marine sediments. Check out those δ¹³C values!!

🚨🚨New Paper Alert🚨🚨

We have a new paper out in Earth & Planetary Science Letters () entitled “Indian margin methane hydrate dissociation recorded in the carbon isotopes of benthic (Miliolida) foraminifera”

Main take home message: we have identified a group of (unicellular organisms living at the bottom of the ) whose shell chemistry carries signatures of dynamics within .

New paper out by @willerstorfi et al. in documenting the evaluation of planktic foraminiferal Na/Ca as a proxy for ocean salinity using plankton tows, sediment traps, and core tops: sciencedirect.com/science/arti?

Take home message: looks like this proxy can be quite complex due to varying Na-bearing phases of the foraminiferal calcite, even though the Na/Ca in some of these phases may be strongly correlated to salinity. The authors conclude instead that due to the effect of [CO₃²⁻], foraminiferal Na/Ca over Cenzoic timescales may be a better proxy for major ion chemistry than salinity changes in the ocean.

Using some modified scikit-learn examples to make a schematic showing how your statistical model might matter more where you don't have data.

Tuesday - greatly enjoying using Anonymous Pro (marksimonson.com/fonts/view/an) these days for most text entry (DayOne/Obsidian etc.) Preference for using fixed width fonts has increased over the years…

@atthenius Haha I guessed that - was curious about the metal though! Also legendary lab mates there; I know Tom M is a big metal fan! Trip out to Az in order to get you nostalgic about picking? 😅

@atthenius Thanks! What kind of metal are you into? I generally find drone (or audiobooks) to be most fitting for picking 😁

@kau These are super cool. I wish I’d had these when I started grad school — they would have made the monotony of picking palatable with a respectable soundtrack.

‼️Publication claxon‼️

Led by former student in my lab @raventurelli@twitter.com and other collaborators (on that other site), we find layered lake #sediment! So, what? That's been done before, you say?

Well, this lake was under 1100 m of Antarctic ice and had never been accessed by humans before we cleanly (no #microbial contamination, and no easy feat!) accessed it! These sediments give us an idea of how long #Antarctic #subglacial #lakes exist.
