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…

@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.

The upper ocean heat content (0-700 m) is just as striking and rising well above the graph's upper limits for the 2022 annual update...

#Arctic sea ice in the Barents Sea continues to remain new record low levels. I will have more on this in a blog late next week!
