Spatiotemporal Sea-Level Fingerprinting of Meltwater Pulse 1A with Transient Rheology Reveals Pole-to-Pole Cascade of Ice Loss
AGU 2024
paleoceanography and paleoclimatology | 13 december 2024
Allie Coonin, Harriet C. Lau, Sophie Coulson
Over the last deglaciation, global sea-level rose by ~120-130 meters, punctuated by episodes of rapid sea-level rise. One such event, Meltwater Pulse ...

The Co-Evolution of a Planet’s Water Budget and its Tectonic Regime
AGU 2024
study of earth's deep interior | 12 december 2024
Manar Al Asad, Harriet C. Lau, Greg Hirth
The viscosity structure of the mantle plays an important in a planets tectonic regime. In particular, Al Asad & Lau (2024)[1] found that asthenosp...
