Map showing which climate element was most unusual in winter (Dec-Feb) 2022-23. I looked at high snowfall, warm anomalies, cold anomalies, wet anomalies, dry anomalies, cloudy anomalies, and uncloudy anomalies. The period of analysis is the last 50 winters and whichever element had the highest rank (most uncommon) was mapped. @AlaskaWx

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.

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…

@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.

Chalk another one up for the ever-charismatic universa - this time as 's classic, From Mars to Sirius.

‼️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.
