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 ...

Deep ocean microbes are starving but does feeding them fresh carbon make them eat the old stuff?

Our new study shows it doesn’t. The persistence of this carbon appears to come from its chemical stability, not from microbial starvation.

Testing the priming effect in the deep ocean: are microorganisms too starved to consume recalcitrant organic carbon?

I met Dr. David Ho!

He’s responsible for the fact that HIV is no longer a death sentence and his work has saved tens of millions of lives. Why he doesn’t have a Nobel Prize is beyond me. AMA.

That was a M3.0 earthquake located 16 km SW of Duncan and 40 km WNW of #Victoria. Shaking was lightly felt across the region.
