I wonder if this year is an #irruption year for Diamondback Rattlesnakes in southern Arizona—have anecdotally heard abt several encounters recently (or perhaps it’s just seasonality) #Western #Diamondback #Rattlesnake This one seen at #Sweetwater Wetlands in #Tucson

Monthly ebook releases on Amazon were basically flat before the release of ChatGPT and other LLMs. Now around 2/3 of all ebooks released on Amazon are fake.

This is absolutely tragic 😢

Fire is out at the USF St Petersburg College of Marine Science - happily nobody was injured, but it doesn’t look good for the building

The #Saguaro cacti have started to bloom this year in Tucson with their charismatic and beautiful white flowers

As my #Paleontology class draws to a close this semester, I ask my students to do a group project where they choose a(n extant or extinct) species & dive deeper into its #phylogeny... Here is a slide from this group that chose Homo sapiens 😂

Check out Yohan's new pre-print (w cool results!) focusing on individual foraminiferal analyses (IFA) in the tropical Indian Ocean!

Roadrunners are absolutely gorgeous dinosaurs; always an aura of mystique & majesty w them! 🪶

Happy Earth Day

Molluskan dominance!! 🤯

This is a FRAUDULENT paper, AI-generated. My name was used as an author and I had nothing to do with it, never saw it until today e-pubmed.co.uk/journals/dig... The "Editors" Angelo Rossi Mori, David Mensah, and Zarnie Khadjesari and this "Journal" should be reported.

Japanese Earth science word of the day: 有孔虫 (ゆうこうちゅう - yuukouchuu) - foraminifera. Foraminifera are single celled organisms that secrete a carbonate shell-like "test". Foraminifera fossils are abundant in marine sediments and are used extensively in paleoclimate research.

⚒️🌋🌊🦠(🐋)📉❄️ In a new paper we hypothesize that explosive volcanism in the Andes, some ~10–6 million years ago, “fertilized” the nutrient-starved Southern Ocean, with nutrient-rich ash that may have stimulated enormous plankton blooms & marine ecosystem changes. Link: www.nature.com/articles/s43...

El Nino thread! Buckle up! I'm turning all the things I'm muttering to myself into a thread.

Happy publication day to me! I am very excited to share that my first chapter of my PhD has been published in Climate of the Past today. cp.copernicus.org/articles/22/...

The bright red rocks of Bryce Canyon are part of the Claron Formation. Deposited in lakes and streams between 40 and 60 million years ago, they contain a variety of sedimentary rocks. Uplift and erosion haved worked away at them since. Bryce Canyon National Park, Utah, 12 Apr 2014. #NationalParks

Celebrating Dr. Jay Quade’s life today.

At NORCE Research and the Bjerknes Centre for Climate Research, there is a vacancy for a postdoctoral fellow position within paleogenomics of the Arctic Ocean. 🌊 🧪It is a period of 3 years, to strengthen our ERC Synergy project @i2b-erc.bsky.social Apply: karriere.norceresearch.no/en/jobs/7334...

The word “unprecedented” gets thrown around a lot these days to describe the ongoing heatwave across the Western U.S., and let’s be honest — it’s absolutely justified. Perhaps the most impressive multi-day event since the 2021 PNW heat dome.

Led by PRL student Deepak Rai, we recently had a new paper out showing that the Oxygen Minimum Zone in the Arabian Sea *expanded* in size during the last glacial cycle @arvindocean.bsky.social agupubs.onlinelibrary.wiley.com/doi/full/10....

Wondering how *anything* can be "broadly stable" across the Pleistocene Ice Ages...

Fantastic work by Aidan Starr, @ianhall.bsky.social & colleagues published in Paleo Paleo yesterday: Subsurface-to-deep C isotope gradients in the Southern Ocean across the MPT! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

“The authors claim these are spherule fragments identified as cosmic impact indicators. During expert consultation, these have been identified as marine foraminifera.” 💀

A suite of benthic δ18O stacks intended as updates to the LR04 has been published. We compiled new data, updated the chronology, and provided regional stacks. gchron.copernicus.org/articles/8/8...

Starting my academic reading this year with a fascinating study documenting the frequency of tropical cyclones in the South China Sea over the past ~650 years. We need more of this type of data to understand extreme weather patterns and their relationship with climate. www.pnas.org/doi/10.1073/...

The Prudhoe Dome, currently a 500m-thick ice dome attached to the northwestern Greenland Ice Sheet, completely melted away ~ 7,000 years ago in response to Holocene warming. www.nature.com/articles/s41...

Here's a majestic Northern Harrier in flight, spotted in Avra Valley (southern AZ) 🪶 Fun fact: apparently Northern Harriers are moving their range into NE Russia for the first time in recorded history over the past few years (link.springer.com/article/10.1...)

Led by Pete van Hengstum (Texas A&M), we have a new article out focusing on water balance ☔️ in the #Caribbean region over the past two millennia (+ implications for future changes under #climatechange), using a coastal Blue Hole in the Bahamas as a natural archive! www.nature.com/articles/s43...

Finally out! The outcome of a virtual workshop in Feb 2024 with modelers and observationalists to put together data and protocols to include historical changes in ice sheet/ice shelf discharge in CMIP models. Hopefully not too late for some CMIP7 runs! gmd.copernicus.org/articles/18/...

Jay was on my PhD committee and taught me carbonate geochemistry, and to approach my speleothem problems with patience and depth. I’m deeply grateful for the time I got to learn from him. His influence will always remain a part of my journey. Will miss you, Jay!

A sad piece of news: I am heartbroken to learn that Jay Quade passed away today—a profound loss for our geoscience community. Jay was an inspirational scientist, an exemplary colleague, and an extraordinary human being. I’ll miss you, Jay! 😞

I'm also quite happy that Yair Rosenthal (a friend and mentor) and @anya-hess.bsky.social wrote a Perspective on our work. www.science.org/doi/epdf/10....
