Hot off the press! New paper characterizing storage and release processes in two permafrost catchments with @theoryofciaran.bsky.social @seankcarey.bsky.social. We characterized these processes by closing the water balance, EMMA, and StorAge Selection Functions (1/n) doi.org/10.1029/2024...

Excited to share our new review in Reviews of Geophysics! We explored the latest advances in tracer-aided mixing models for studying water in the Critical Zone. We synthesize new tracer methods, models, & key insights. I think it'll be a valuable resource for the community doi.org/10.1029/2024...
Recent Advances in Tracer‐Aided Mixing Modeling of Water in the Critical Zone
Tracer-aided mixing models are uniquely capable of identifying water flow paths and sources within the Critical Zone
Recent advances offer novel tracers and models for deeper and more accurate in...

Low-relief catchments are super complex and awesome, but they have not received as much attention as our complex and awesome high-relief catchments. Here we show in a low relief catchment just how complex things can be and how spatial sampling frameworks help us solve stream chemistry mysteries!
My first paper of my PhD research on catchment biogeochemistry in Michigan is live!
Wetlands, Groundwater and Seasonality Influence the Spatial Distribution of Stream Chemistry in a Low-Relief Catchment

Hydrology Paper of the Day @gregverkaik.bsky.social @micaheckert.bsky.social @peatofmind.bsky.social on how changes to drainage and spatial burn patterns affected biogeochemical cycles and vegetation cover in a peatland: depth of burn, carbon loss, and burn severity in context of a fuel load model.

The role of catchment characteristics, discharge, and active- layer thaw in seasonal stream chemistry across 10 permafrost catchments
Abstract. High-latitude catchments are rapidly warming, leading to altered precipitation regimes, widespread permafrost degradation, and shifts in stream chemistry across major arctic rivers. In headw...
