AGU Session: High Latitude Nutrient Cycling, Dec 9-13, 2013

Abstracts are currently being accepted to the 2013 AGU Fall Meeting Session “GC046: Altered Nutrient Cycling in High-Latitude Ecosystems.”

Abstract Deadline: August 6th, 2013

Description: Despite strong nutrient limitation at high-latitudes, less attention is paid to climate change impacts on nutrient cycling than to direct effects on carbon cycling. In addition to a potential source of nutrients with permafrost thaw, climate change may alter disturbance regimes (i.e., fire), hydrology (i.e.. water tables) and vegetation communities (i.e., shrub expansion). These factors influence nutrient inputs, cycling and transport. In this session, we propose to explore how changing climate alters nutrient dynamics in permafrost-dominated ecosystems. We welcome presentations on the cycling of N, P and other nutrients, especially those on disturbance effects, terrestrial-aquatic linkages and growing season controls on productivity.
