Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social

Persistent eastern equatorial Pacific Ocean upwelling since the warm Pliocene
Upwelling generates a nutrient-rich “cold tongue” in the eastern equatorial Pacific Ocean (EEP), with impacts on global climate, oceanic biological productivity, and the carbon cycle. The cold tongue ...

Especially honored to have received Honorable Mention in the Biogeochemical and Climate session. Could not have done it without my advisor @jfarmersalmanac.bsky.social and colleagues for their guidance and support. Already looking forward to #ICP16

Leaving #ICP15 feeling inspired and motivated. Special thanks to all the organizers for making this week possible. I had a blast learning from the star-studded list of speakers and learning about on-going projects.

Also making a plea for new research ship to replace the JOIDES Resolution and continuation of deep sea drilling -post IODP 2 - as still lots of new discoveries to make and under-explored regions.

I promise to write a serious thread of what (IMHO as Peisong's advisor) is an innovative analysis. This will have to suffice for now.

And just like that my time at MPIC has quickly come to an end! 6 weeks later and ~250 new data points to play with. Here’s me celebrating with my last oxidation sandwich. I was only slightly tempted to eat it 🥪

It’s been two weeks since the PaleoLab landed in Mainz, Germany and we’ve certainly been making the most of our time. All our trainings have prepared me for this massive first ~26 hr IRMS run. Happy data soon to come! 🐚🌊

The history of the ocean, as told by tiny beautiful fossils
Bountiful remains of foraminifera reveal how organisms responded to climate disturbances of the past. They can help predict the future, too.
