New paper out by @willerstorfi et al. in #GCA documenting the evaluation of planktic foraminiferal Na/Ca as a proxy for ocean salinity using plankton tows, sediment traps, and core tops: https://www.sciencedirect.com/science/article/abs/pii/S0016703723001187?
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.

#Typography Tuesday - greatly enjoying using Anonymous Pro (https://www.marksimonson.com/fonts/view/anonymous-pro) 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 #Orbulina universa - this time as #Gojira's classic, From Mars to Sirius. #foraminifera #deathmetal
#Benthic #foraminifera Bulumina aculeata as #Autopsy's Macabre Eternal. #deathmetal #forams
‼️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.

#Planktic #foraminifera #Orbulina #universa back at it again this time as #Sleep’s #HolyMountain
#Foraminifera resembling #metal #albumcover #artwork (resurrecting a 🧵 from the birdsite).
A classic to begin with - Orbulina universa as #MorbidAngel’s Altars of Darkness

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!
