#stableisotopes

Today is #200years of the #9thsymphonyofBeethoven. WATSON celebrates #friendship and #collaboration among people and among peoples, in the name of #science, #progress, and... #stableisotopes

New #dataset in #datasuds Sardenne, Fany et al. 2023, "Lipid-correction models for δ13C values across small pelagic fishes (#Clupeiformes) from the Atlantic #Ocean (2020-2022): sample #fish #data", https://doi.org/10.23708/URQ9IJ #researchdata #openscience #stableisotopes #trophicecology link to publicaton doi: 10.1016/j.marenvres.2023.106213 

Nerdy details: we show using #stableisotopes of #carbon (δ¹³C) and #oxygen (δ¹⁸O) that **ONLY** Miliolida benthic foraminifera (including #Pyrgo, #Quinqueloculina, & #Spiroloculina - 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!!

High-resolution #Isotope analysis of #TreeRings: #StableIsotopes in tree rings provide insights on the #Climate of the past and on physiological reactions of #Trees to climate - here, we give an update on the current status of laser ablation research for high resolution, high throughput analysis of wood carbon isotope ratios: https://academic.oup.com/treephys/advance-article-abstract/doi/10.1093/treephys/tpac141/6909002?login=false

Oh wow! For anyone interested in #StableIsotopes this paper is exciting!

Lower sample size needed for #carbon and #oxygen measurements in #tooth #enamel and they were able to measure #nitrogen from enamel!

x-post for the ISBA board (no mastodon presence [yet]):

Membership for the International Society for Biomolecular Archaeology (ISBA) is now open!

You can join here: https://www.isbarch.org/membership

As well as funding initiatives to support the field of biomolecular archaeology, it includes
discounts for registration at the forthcoming ISBA symposia.

Please boost!

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!

Thrilled to have made it to the lab in #SouthAfrica to select #MiddleStoneAge and #LateStoneAge #fish and #seals for #StableIsotopes! More fish, seal, and marine sustability content to come…

I'll do a real #Introduction later. Have some random hashtags instead:
