These findings highlight the dual threats that deep coral reefs in the ETP face in the 21st century: the intrusion of warm water (e.g. during a large El Niño) from above and the intrusion of cold water from below (e.g. during a large La Niña)

Here we link this cold-water bleaching to an anomalously shallow thermocline in the ETP, and demonstrate that oceanography and climate play a significant role in modulating the functionality of Mesophotic Coral Ecosystems in the Eastern Tropical Pacific.

Check out our newest paper: doi.org/10.1016/j.scit… In 2023, we conducted a field campaign at Clipperton Atoll, a remote atoll in the Eastern Tropical Pacific (ETP). While there we observed a severe cold-bleaching event occurring along the deep reefs (>30m).

Check out our cool new paper! aslopubs.onlinelibrary.wiley.com/doi/10.1002/ln… Here we show that guano is an important source of N to the reef via groundwater - following its conversion to nitrate - and that we can potentially use its signature in coral skeletons to track bird populations in the past!

Tropical Climate Variability & Coral Reefs SPP2299
If you’ve missed it we have had over 50 researchers from our #SPP2299 members and other invited collaborators come together this week in Bremen, Germany to talk about thermal stress indicators in tropical corals. Follow along for updates on the meeting! @dfg_public

EXCITING DISCOVERY: #GalapagosDeep2023 have found the largest known Galapagos #reef in the #deepsea waters of the platform using #Alvin. And its beautiful 🤩 Unusually high % live coral (Madrepora), as far as the eye can see. Check video out: bit.ly/41c5xH6 1/2

Why are some corals more resilient to climate change than others? Our @stri_panama dives into this question in the latest episode of their podcast, Biodiversa. striresearch.si.edu/biodiversa

Excited to have been a part of the newest paper from Jen Leichliter and the Lüdecke group:, which you can find here: nature.com/articles/s4200… This work shows enamel preserves trophic information, opening up an exciting new avenue of research to better understand past food webs!

Today marks the departure for Clipperton Atoll, in the remote Eastern Tropical North Pacific aboard the S/Y Acadia! We are traveling there to study the effects of climate change (and in particular the evolution of oxygen deficient zones) on remote coral reefs. Stay tuned!

Hot off the press! A brand new article from the Lüdecke lab, the @AMG_lab, and many collaborators. This paper demonstrates the great potential of tooth enamel, and in particular N isotopes in tooth enamel, as an archive of diet and past climate: frontiersin.org/articles/10.33…

New paper alert! In this study by lead author Tony Wang (together with @AMG_lab, @ChemClimatology, and others) we show the expansion of the Pacific oxygen deficient zones (ODZs) over the last 8 million years using foram-bound nitrogen isotopes in the SE Pacific. (1/3)

I'm lucky to get to collaborate on such exciting stuff! Here you can see ongoing work by the HoMeCo group (Tina, Jen, Sven, and Marisa) in Mozambique. Ultimately nitrogen isotope analyses on fossil teeth have potential to unlock major transitions in fossil food web structure.

Field work @GorongosaPark, Mozambique: Tina Lüdecke, head of the research group Hominin Meat Consumption @MaxPlanckChem, and PhD student Sven Brömme excavate fossils with team members of the Paleo-Primate Project Gorongosa to then analyze stable isotopes of fossil tooth enamel.

Check out the newest AMG lab paper here: doi.org/10.1029/2022GC… In it we examine how well the organic matter is preserved within the various fossil materials (carbonates, apatite, diatoms) that we measure in our lab. It seems, in short, that they do so quite well. Great news!
