💥California marine biogeochemists!
So Cal BOOM* is at UCLA on November 22, 2025 (*Biogeochemical Ocean Obs & Models). This is an event for grad student and post-doc marine biogeochemists of all kinds. More senior peeps (like me) are also welcome!

So many people to thank for this (see acknowledgments below), but also my huge thanks to all the co-authors. Danny Sigman and his lab (where we made all the foram-bound N isotope measurements) and co-lead author @jfarmersalmanac.bsky.social for special shoutouts

We built a box model to help explain how changes in wind-forcing (x axis) in the warm Pliocene might be balanced by decreased surface ocean stratification / increased buoyancy (y axis). Huge shout out to anonymous reviewer for asking for this and @oceansclimatecu.bsky.social for making it happen!

The point of making planktic foraminifera-bound N isotopes is that they: (1) Largely record the same N isotope value as nitrate and (2) That N isotope value is safely locked inside the carbonate test of these microscopic fossils.
We found the same trends!

The mystery of the weakened winds / upwelling deepens with our new bulk sediment N isotope (d15N) data from the east and western equatorial Pacific (top of image below). (This dataset was largely completed about 10 years ago, but their unusual nature made us cautious about publishing)

Speaking of temperatures, a recent understanding of the equatorial SST suggests the eastern cold tongue has been getting colder relative to the west over the past 5 million years. This has important implications for global climate change (i.e., the ice ages) over this time (top of this plot)

However, even though nutrients don’t “matter” with respect to ENSO, my work (see above) indicates that nutrient utilization in these iron limited waters is surprisingly linked to the same upper ocean physics altered by ENSO. See the Nature Communications paper or Oceanography Society papers above

The key point in the figure above is that the trade winds drive upwelling along the equator, leading to the existence of both an eastern “cold tongue” and higher concentration “nutrient tongue”. The temperature distribution is critical for the air-sea feedback driving the trade winds and ENSO

These earlier papers laid a foundation to accurately interpret the unusual records of east & west equatorial Pacific N isotopes (d15N) since the warm Pliocene (~5 million years ago). First, let's look at tropical Pacific nitrate and temperature with depth (A) and at the surface (B) and (C)

I'm also quite happy that Yair Rosenthal (a friend and mentor) and @anya-hess.bsky.social wrote a Perspective on our work.

Many NOAA databases are scheduled to be decommissioned, including several I frequently use (IMLGS; sediment core database) and are crucial to my work. But there's also databases that normal people care about (earthquakes!).
Can we download these in their entirety and host them somewhere else?

I’m not sure I can thank @bobkopp.net enough for pointing us to this treasure trove of Richard Alley videos!
(I particularly love the Earth history video to the tune of Billy Joel’s “Piano Man”)

Congrats to all around good (also v. smart) guy Richard Alley!
He didn’t need to, but he recently helped me out of a really tight spot. I think he helped me because he’s a great person and wants to help science and scientists. Need more like him out there!
