Vegetated coastal ecosystems sequester carbon rapidly relative to terrestrial ecosystems. Coastal wetlands are poorly represented in land surface models, but work is underway improve process-based, predictive modeling of these Here, we identify guiding questions, potential simulations, and data needs make progress improving representation vegetation terrestrial-aquatic interfaces, with a focus on estuarine We synthesize relevant plant traits environmental controls that influence cycling...
Abstract Redox processes, aqueous and solid‐phase chemistry, pH dynamics are key drivers of subsurface biogeochemical cycling methanogenesis in terrestrial wetland ecosystems but typically not included carbon cycle models. These omissions may introduce errors when simulating systems where redox interactions fluctuations important, such as wetlands saturation soils can produce anoxic conditions coastal sulfate inputs from seawater influence biogeochemistry. Integrating redox‐sensitive...
Aircraft anti-icers and pavement deicers improve the safety of airport operations during winter precipitation events. Runoff containing these products can contribute elevated biochemical oxygen demand (BOD) to receiving streams. We monitored runoff from Milwaukee Mitchell International Airport at one upstream site, three outfall sites, downstream site 2005 2022 for BOD, chemical (COD), freezing point depressants used in deicing anti-icing fluids determine primary sources BOD COD stream.

Redox processes, aqueous and solid-phase chemistry, pH dynamics are key drivers of subsurface biogeochemical cycling in terrestrial wetland ecosystems but typically not included carbon cycle models. These omissions may introduce errors when simulating systems where redox interactions fluctuations important, such as wetlands saturation soils can produce anoxic conditions coastal sulfate inputs from seawater influence biogeochemistry. Integrating redox-sensitive elements could therefore allow...
Abstract Elevated inputs of sulfate to freshwater systems can increase sulfide concentrations in anoxic soils and subsequently destabilize aquatic plant populations, but the interactions between sulfate, other geochemical cycles, interannual population cycles are poorly understood. Increased loading increases mineralization nitrogen from litter, produced during this process limit uptake by plants. In some cases, iron may mitigate sulfide's impacts on plants precipitating sulfide. We examined...

Meso-scale weather systems such as atmospheric cold/warm fronts and winter storms have been found to greatly influence hydrodynamics of coastal water bodies with an increasing frequency in recent decades. To better understand how on ecosystems, the Land Model Energy Exascale Earth System (ELM) is used simulate nutrient cycles wetland plant species. The ELM has upgraded incorporate more realistic tidal hydrologic processes two types communities terrestrial-aquatic interfaces. Sensitivity...
