Permafrost & Hydrology Wetlands Group Lead Influencing Climate Research
Permafrost and hydrology experts gather to analyze trends, drivers, and impacts on climate systems. Leading researchers and attendees collaborate on synthesis activities to explore aquatic trends, zero curtain modeling, and methane emissions across the ABoVE domain. From understanding permafrost dynamics to harmonizing aquatic products, this group aims to advance knowledge on climate change effects in wetland ecosystems.
