Here in the tropics, climate "disruption" can upend predictable processes that coastal communities rely on. There are many regionally-important upwelling zones across the tropics. All need better monitoring and climate predictions. Great collaboration with @mpic.de.‬ OA! www.pnas.org/doi/10.1073/...

More than 95% biomass of Panama's fisheries comes from the Pacific coast and the #1 largest export of Panama is sea food. Upwelling is economically critical for Panama and its people. Is this a one-off or a vision of the future? Photo: Steve Paton/STRI

It appears the culprit was dramatically reduced wind patterns—74% fewer northerly winds with much shorter duration when they did occur. Just not enough to kick-start the upwelling...

We analysed long term records of temperature and wind in collaboration with the Max Planck Institute for Chemistry using the Smithsonian Tropical Research Institute's long term monitoring program data. Here's to institutional monitoring!

This seasonal upwelling is driven by the trade winds, and it brings cold, nutrient-rich water to the surface. Year on, year out it has predictably supported ocean life and fisheries for millennia. The cooling waters also protect coral reefs from heat stress. Photos: Natasha Hinojosa and Steve Paton

While writing this paper, our labs underwent their own trophic cascade! We used to have a few scorpions here and there. Administration put out scorpion poison and the we became infested by millipedes (?Chondrodesmus)

While all this was going, the cryptobenthic fishes showed remarkable stability with no change in body size or abundance over 7,000 years. Are they immune to the cascading effects of predation or are bottom-up factors more important? Photo by @gobyone.bsky.social

We also looked at the frequency of damselfish bite marks on Acropora coral. They increased nearly 10-fold on modern compared to ancient reefs, suggesting more damselfishes and again, reduced predation. Photo of S. planifrons in Bocas del Toro by @hannah-rempel.bsky.social

We found that sharks and fishes that are commonly targeted by humans are >50% depleted and 22% smaller today than 7,000 years ago. Expected given long term exploitation!

What surprised us was that prey fish doubled in abundance and are growing 17% larger today, suggesting release from predation
