Abstract The rapid warming of the Arctic where permafrost is prevalent is threatening to release carbon which would accelerate global warming if it reaches the atmosphere. There are many unknowns regarding carbon cycling and budgets in Arctic watersheds. This presentation shows that active layer soil above permafrost functions as a thin but extensive unconfined aquifer made up of mostly of peat. The supra-permafrost aquifer has relatively high porosity and permeability, creating efficient subsurface flow paths above otherwise impermeable permafrost. Observations and modeling reveal that much of the water and carbon going through Imnavait Creek, a headwater river in the North Slope of Alaska, has passed through the supra-permafrost aquifer. Remote sensing showed that supra-permafrost groundwater is prevalent during summer while extensive sampling showed that there is substantial carbon within the supra-permafrost aquifers, as much as those estimated for permafrost. The crucial task of predicting the fate of carbon in Arctic watersheds depends on knowing the subsurface flow properties and processes.

Bayani Cardenas is a hydrology professor in the Department of Earth and Planetary Sciences of the Jackson School of Geosciences at the University of Texas at Austin. His research seeks to understand flow and transport processes across different hydrologic settings, water quality and quantity problems, and scales, using a combination of theoretical, computational, and observational methods. He received his education from the University of the Philippines-Diliman, the University of Nebraska-Lincoln, and the New Mexico Institute of Mining and Technology.

Hi everyone, Next Wednesday (May 7), we’ll be having our regular Storm Tracks group meeting from 14:00 to 15:00 in room U105 (near the canteen). Kjersti will share us some preliminary analysis on the connection between the front and cyclone lifecycles, which we’re looking forward to discussing. The meeting will be hybrid and here is the zoom link for those who want to join remotely. https://uib.zoom.us/j/62886269543?pwd=ajWbi97zr0hbniaoQdZkUtD2EUSSri.1 Meeting ID: 628 8626 9543; Password: qSKTfKU3
