I’ve been greatly enjoying the storytelling in Johnathan Meiburg’s A Most Remarkable Creature—centered on the Falkland Islands’ Striated Caracara. Wonderful stuff!

@npub1e5c…nflr Ah! So it has to do with the fact that the subsurface-dwelling planktic foraminifera are living in "older", deeper waters (~500 m), as opposed to the others which are living in upper waters at the surface (0-50 m). While making shells, the surface bugs readily equilibrate with atmospheric radiocarbon (and hence gives accurate dates). The scientists are looking at dating sediment cores taken from the bottom of the ocean, which contain shells deposited from above; but plankton that lived in 0-50 m and >300 m (and even those living at the ocean bottom), all "co-occur" in the sediments (or mud/clay) that is brought in by rivers or wind. This is why its important to only date shells of surface-ocean species of plankton from marine sediment cores as opposed to the deeper-dwelling ones (w nice experiment borne out in that article).
If two types of plankton were living in the same waters, their source of carbon is the same, and hence their shells will not give different ages.
Sorry to be long, but hopefully simple!

A nice, new #study out by Jörg Lippold & colleagues on #radiocarbon differences in co-occurring planktic #foraminifera. They document how subsurface-dwellers like G. truncatulinoides have ages offset, on average, by ~300 14-C yrs compared to surface-ocean species (like G. ruber & T. sacculifer).

@npub153s…cvd9 I *just* visited the National Museum of Anthropology in México City (fresh on my mind — yesterday!) and boy, hands down, my favorite and most impressive museum I’ve ever visited! Why? The collections are MASSIVE and the exhibits are so well curated; indigenous peoples and civilizations of Mesoamerica are represented excellently in space & time. To top it all off, the architecture is stunning!

Interesting to see what the #LoopCurrent is up to right now: looks like it is about to shed a warm-core #eddy — especially considering the prevailing easterlies. Wonder how this might affect the upcoming #Atlantic #storm season...

Mainly focusing on coral-derived records, we also highlight a recent article by Ong et al. (2022; https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022PA004483) who add a new #coral genus to the #paleoclimate toolkit.

Very proud of our #NSF-funded #REU students at the Dept of Geosciences, University of Arizona — our program called “Clouds 2 Core” (C2C) is only for students enrolled in 2-Yr Community and Tribal Colleges and the current cohort of 11 students are from colleges and towns all over #Arizona (and #NM and #TX). Today is their final presentations after 8 weeks of research work, here in #Tucson. Some photos below!
