Introducing "TEXAS" — a PSM for #TEX86!
Culture & mesocosm data constrain T response above 30°C. Ring Index brings culture/mesocosm GDGTs into agreement with coretops. Not linear, not exponential — the T–GDGT relationship follows a logistic S-curve.

The tropics are hot, and during the early Eocene hyperthermals, they were ever hotter. But surprisingly, while there are reports of harmful algal blooms during some key events, the planktonic ecosystem shows remarkable resiliance across them. 🧪🌊⚒️

2 patterns to look for here:
1) Samples with #TEX86 should show low GDGT-2/-3 (more GDGT-3 at higher T). This is our expected #thermal pattern.
2) The opposite occurs with core-top sediments. We called this #nonthermal pattern.
We investigated #GDGTs from 7 archives!!
