New paper from Julio and I on marine OH-GDGTs around Iceland. TL;DR nitrate concentrations and water-column stratification are best correlated to OH-GDGT distributions, and not temperature (at least for Iceland...) www.frontiersin.org/journals/ear...

Frontiers | Impact of non-thermal variables on hydroxylated GDGT distributions around Iceland

Many thanks for helping OH-GDGT-based paleothermometry to keep progressing through its « pessimism » phase, as I and a few other researchers initially contributed to its initial « optimistic » phase. One day, I will find out how well OH-GDGT-based paleothermometry would work in another polar ocean.
