Calcareous fens in Southeast Alaska.

Calcareous fens have not been identified previously in southeast Alaska. A limited survey in southeast Alaska identified several wetlands that appear to be calcareous fens. These sites were located in low-elevation discharge zones that are below recharge zones in carbonate highlands and talus foot-slopes. Two of six surveyed sites partly met the Minnesota Department of...

Vulnerability of wetland soil carbon stocks to climate warming in the perhumid coastal temperate rainforest

The perhumid coastal temperate rainforest (PCTR) of southeast Alaska has some of the densest soil organic carbon (SOC) stocks in the world (>300 Mg C ha^-1) but the fate of this SOC with continued warming remains largely unknown. We quantified dissolved organic carbon (DOC) and carbon dioxide (CO₂) yields from four...

Fluorescence characteristics and biodegradability of dissolved organic matter in forest and wetland soils from coastal temperate watersheds in southeast Alaska

Understanding how the concentration and chemical quality of dissolved organic matter (DOM) varies in soils is critical because DOM influences an array of biological, chemical, and physical processes. We used PARAFAC modeling of excitation-emission fluorescence spectroscopy, specific UV absorbance (SUVA₂₅₄) and biodegradable dissolved organic...
