New article out in #Paleoceanography & #Paleoclimatology where we (Chris Maupin & myself) briefly recount how scientists have sought to understand past year-to-year (#interannual) temperature variations in the marine realm: https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2023PA004723

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.

The Department of Earth & Planetary Sciences at #UCDavis is looking for a Visiting Assistant Professor in #Paleoceanography: https://recruit.ucdavis.edu/JPF05722

Happening now at #AGU22 (E354a): the Emiliani lecture being delivered by @coralsncaves!

A full on #Rutgers lineup here at the Indian & Southern Ocean (paleo)circulation session in S403b. First, Jim Wright provides a fresh (first?) look into Argentine drift sediments and the insights they hold regarding Neogene glaciation.

Now: Liz Sykes talks about the history of δ¹³C in the southeastern Indian Ocean and its implications for deglacial carbon change.
Take Home MEssage: Differential δ¹³C histories of proximal cores

Mark Yu, from #Rutgers, gives an interesting talk about reconstructing #monsoon variability from sediment cores offshore the #Maldives and finds that the isotopic difference between this record and foraminiferal records from the Arabian sea and Bay of Bengal, are a reflection of monsoon variability. #AGU22 #Paleoceanography

Now at S405a (#AGU22) - Central University of #Kerala Ph.D. student, Ammoose Jayan (also currently a Fulbright visitor at the #UniversityOfArizona), talks about #paleoceanography investigations in the Gulf of #Mannar (#IndianOcean) focusing on paleoproductivity changes across the late Holocene using #planktic #foraminifera. Main result: lower productivity in Gulf of Mannar along with a relatively weaker #Indian summer #monsoon winds during the Little Ice Age (#LIA), some ~500-700 years ago.

I wonder about the potential impact on coastal southern Indian societies & seafood intake during the time!

My #firstpost on #Mastodon:

🌏 🌊 I am an Earth/climate scientist at the University of Arizona in #Tucson (southwestern US) focusing on the areas of #climate change, #paleoclimates, and #paleoceanography, with an emphasis on #ENSO, #monsoons, & #variability.

⚗️🐚 Our group uses #inorganic #geochemistry incl. measurements of #stableisotopes & #tracemetals in #carbonate rocks & #fossils (e.g., #foraminifera, #mollusks, & #speleothems) alongside climate #observations as well as #simulations to advance understanding of how the Earth's #climate & #oceans have changed in the past and can change in the future.

Some of my hobbies include:

🎵 #music: I am a fan of #metal and heavy music of all sorts, but tend to migrate towards #black, #death, #doom, #drone, #sludge, & #thrash. I also have a soft spot for #carnatic/#hindustani #ragas, #darkambient, oldschool-ish #hiphop, #triphop, and various forms of #electronicmusic.

🦜 #birds & #birding #photography bring me joy. Right now, I feel v lucky to be briefly back in my hometown of #Bengaluru, southern India, after three long years being able to see #oldworld birds I grew up with.

👨🏾‍💻 #GTD, #mindfulness, #organization, and (vs?) #producivity are things that I enjoy thinking about. Of late, I've been using #Things3, #Streaks, #Hobonichi w a #Lamy Safari, #Obsidian, #Overleaf, & #Bookends to get things done.

🙏🏽 Thanks for reading!

Not #ForamFriday, but I'd like to kick off mastodon by introducing this beautiful #benthicforams called Globobulimina, a microfossil that I'm using to reconstruct bottom water temperatures changes in the last 30.000 years at intermediate depths of the eastern North Atlantic 🧐🐚🔬the #deepocean from the past has a lot to tell us :ablobattention: :ablobcatbongo: #micropaleontology #microfossils #foraminifera #womeninstem #science #latinasinstem #womeninscience #paleoceanography #climatechange

As per bio, I am a micropaleontologist working from Berlin's MfN. I work primarily on siliceous microfossils (#Radiolaria #Diatoms) and their relationship with past climate and oceans (#Paleoceanography #Paleoclimatology). I am also a programmer (primarily #R #Python #SQL and a bit of #JuliaLang) and the current maintainer/developer of the Neptune DB (a DB of microfossil occurrences and #Stratigraphy).

It is nice tradition to introduce yourself on #Mastodon. I am a geoscientist, studied #music, #geophysics, and #geology, and have a doctoral degree in #paleoceanography. My research is on the influence of climate in #Africa on human evolution using time series analysis methods. I learned #Fortran77 in the 1980s, have been using #MATLAB since 1992, and recently #Python - and have written several textbooks on data analysis in the earth sciences. I look forward to make new connections with you!

Intro: Just working out this Mastodon thing. As a geologist by training I’m kind of curious about the name and why you would call a social network after a extinct megafauna? A bit about me - I mostly work on oceans and their link to climate through the carbon cycle. I study plankton and biogeochem of the modern ocean, and sediments and isotopes of dead plankton to study the past. I go to sea on large research vessels. I teach oceanography and climate science at an Aus uni. I’m also a cyclist and love to swim in the ocean and hike in the bush and mountains. #oceans #climate #plankton #carbon #ships #isotopes #paleoceanography #Paleoclimates #cycling #hiking
