Now at #AGU22 (S405a): Tyler Winkler from #WHOI talks about using “blue holes” from the Bahamian archipelago to track North Atlantic tropical #cyclone variability over the last millennium - finds anomalously *intense* #tropicalcyclone activity (inferred from several blue hole records) during the Little Ice Age (#LIA) from 1500-1600 CE!
Interesting Monday morning (#paleoclimate) session at #AGU22 (S404) exploring the “nexus” of climate, environment, and humans. First few talks focused on the potential climatic implications for the trans-Eurasian Silk Route exchange.
The #Paleontology world is blowing up:
— Robert #DePalma is accused of faking data in dino-killing #astroid paper (to scoop Melanie During who was publishing on the same subject)
— claims he can’t get the original data as the person who had it passed away
— data transparency is essential & should already be a requirement of EVERY journal!

How does #agriculture respond to compound #climate #extremes, and what are the main areas of uncertainty?
We review it!
An integrated understanding of #heat and #water in soil–plant–atmosphere dynamics is needed to suitably adapt cropping systems to compounding climate impacts

I’m recruiting MSc/PhD students to join my lab at #ClemsonUniversity in Fall ‘23! If you’re interested in #paleotempestology (#prehistoric #hurricanes), the hydro side of #paleoclimate, and/or records of #coastal or #hydrological #hazards, get in touch! We use multiple proxies, primarily #sediment & #treerings, to reconstruct #extreme events in the past. There are plenty of opportunities for #fieldwork & #labwork. If you’re going to #AGU22 & want to chat about this, let me know & we’ll meet up!
July 2022: A superb #Superb #Starling seen in #Amboseli, #Kenya.

One of my favorite #birds to see out in the wild - an Indian Paradise Flycatcher- this one seen a few weeks ago at Hunasinakere in Hassan Taluk, #Karnataka. They seem so ethereal & otherworldly upon first sight!

I missed these birbs - here is a House #Crow at the banks of the #Kaveri River & confluence of its tributaries in #Srirangapatna, #Karnataka, chomping down on rice leftover from an ash scattering (death) ritual.
‘Eat local’ is a common recommendation to reduce the carbon footprint of your diet.
But transportation makes up a very small amount of the greenhouse gas emissions from food.
*What* you eat is far more important than *where* your food traveled from.
The Google doodle today is of Marie Tharp — pretty neat. Marie Tharp (July 30, 1920 – August 23, 2006) was an American geologist and oceanographic cartographer who, in partnership with Bruce Heezen, created the first scientific bathymetry map of the Atlantic Ocean floor while at #ldeo #columbia in the 1950’s. Lamont Doherty Earth Observatory has a visiting researcher fellowship in her name to this day. #womeninstem #geoscience #MappingMondays https://www.google.com/?fpdoodle=1&doodle=240342495&hl=en&gl=us&ictx=3&sa=X&ved=0ahUKEwjciuXz0L_7AhVcFjQIHVBdA5EQPQgR
Ever wondered where the numbered ENSO indices come from?
Rasmussen & Carpenter (1982) numbered ship tracks going across the Pacific and these were adopted for the sub-regions that they crossed.

My first post: Let me share some oceanography history.
The Sputnik plot originated at Lamont-Doherty in the early 1990s. Rick Fairbanks was the visionary behind the plot. He asked Jim Wright, his postdoc, to make the first draft for δ¹³C. Chris Charles then modified it for Charles and Fairbanks (1992) in Nature (submitted mid-1991). Arnold Gordon was Chris' PhD committee chair and was familiar with the plot. He had a version made for meridional overturning circulation in a 1991 Lamont report.
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!
