I’m in this point and I don’t like it

Markus is survived by his wife Stephanie and their 3 daughters: Sophia, Annika and Julia

We had a nice memorial for Markus and others in the paleoceanographic community last summer at the International Conference on Paleoceanography in Bangalore (#ICP15). I hope to make that an on-going tradition for future ICPs

Markus was a few years ahead of me in the academic pipeline and, looking over my notes just now, I see my first contact with him was about how to prepare sediments to analyze the clay-bound N isotopes (one of the many things I did that won't be published). He was always really generous.

Markus was a really good scientist and a great friend. I always enjoyed seeing him at meetings (if not him, most likely I'd see his wife Stephanie; they traded off kid care back home). Quick to laugh, but also a serious scientist—Markus and I had some great scientific debates over the ~20 years!

The acknowledgments section from our paper that says: We dedicate this paper to the memory of our first author, Markus Kienast (1969-2025), who passed away after the submission of this manuscript. Markus was an exceptional scientist, mentor, colleague, and dear friend whose intellectual rigor, generosity, and candor profoundly shaped this work. His enthusiasm for science and his joy in collaboration left a lasting imprint on us and on all who had the privilege to work with him. He is deeply missed. The authors thank Brad Erkkila (Yale Analytical and Stable Isotope Center, YASIC) for 8'SN analysis and Emma Tanguchi (Dalhousie) for sample preparations and determinations of biogenic opal. Birgit Meyer-Schack, Maike Steinkamp, and Henning Kuhnert at the Laboratory for Stable Isotopes (MARUM) are acknowledged for 8180 analysis. Lowell Stott (USC) kindly shared an unpublished age model of core MD98-2177. This study would not have been possible without sediment core material recovered during Marion Dufresne (IMAGES) and RV SONNE expeditions.

With sadness, I report a post-humous publication from our friend Markus Kienast, who passed away last year.

A picture of a library shelf with a small rolled up note on it. The note says “read this” in child’s handwriting.

A picture of the note unrolled. In the same child’s handwriting it reads “beware of the future!!”

Still thinking about this note I found in the children’s section of the public library when I worked there back in 2018. This kid tried to warn us…

Wouldn't it be cool to invest trillions of dollars into a technology that would actually make society better?

Maybe we can call it “HI” — Human Intelligence.

Instead of “data centers”, we could fund “schools”.

Instead of *stealing* art, literature, and science, we help people *create* it.

Crazy!

In 5 days, the crew will be further away from Elon Musk than anyone else has ever been.

Goosebumps!

Watch Director Bhattacharya's performance at CPAC really got to me.

I chose to share some of my observations with him.

Hold on...

Well done. #NoKings

John Dickerson @jdickerson.bsky.social is a national treasure

😂

All of the above!

Usually I’m a solid no to these fund raisers but including this meme along with it… makes me a maybe!

Friend from out of town was visiting campus yesterday. She said hi and that she was on her way to a HAB (Harmful Algal Bloom) meeting.

I'd like the record to show that I immediately—not 10 minutes later, not 1 hour later, not 1 day later—responded with, "well, HAB a nice day!"

very proud

get in losers, we're forming a popular front against fascism

Wow love this description of modern movies

Any ocean (biogeochemical) modeller wants to be part of this fun crowd for a while?

@inquirer.com would like a moment of your time

Gotta check that out!

He was pitching Spring Training yesterday!

Let me tell you about a baseball player for the Philadelphia Phillies, whose name is Charles Fuggit King

He's from Texas, where there must be a long line of people with that middle name—or none at all!

How the Rise of a Salty Blob Led to the Fall of the Last Ice Age - Eos Scientists have long suspected that high salinity levels in the deep ocean were responsible for keeping carbon dioxide locked away during the last ice age. New research finds the strongest evidence…

It’s salty. It’s full of carbon. Its upwelling may have helped end the last ice age. It’s…the salty blob!

I am running a Climate Dynamics reading group for UCI graduate students this Spring and would like to propose a list of accessible papers on "big ideas" in climate dynamics from the 21st Century, prioritizing primary sources over review papers.

Any suggestions of papers? (Self-promotion welcome!)
