Hydrological Carry-Over in the Critical Zone and Feedbacks to Climate

Session ID#: 25010

Session Description:
Extending from the bottom of the weathered bedrock to the top of canopy, the critical zone as a whole harbors many hydrological stores and pathways relevant to earth system functioning at sub-decadal time scales. This multi-layered “living skin of the Earth” is highly heterogeneous both horizontally and vertically; scaling up local insights into an integrated mechanistic understanding of this interface between the atmosphere, the oceans and Earth’s interior remains challenging.

This session collects contributions using modelling- and/or measurement-based analyses spanning local-to-global scales to 1) quantify hydrological fluxes and residence times within the critical zone, and 2) provide insights into couplings and feedbacks with climate seasonal dynamics and short-term variability, ecosystem functioning, and geochemical cycling.
