The study is part of the IPY program and is aimed at measuring the state of Arctic tundra. 2008_CO2_Flux_Welker - This is a study of how different snow regimes effect CO2 exchange in tussock tundra and whether there are shifts in ecosystem C cycling when facets of "drift" effects are isolated. The study is part of the IPY program and is aimed at measuring the state of Arctic tundra. ipyshrubmicroclimate - Hourly air temperature, humidity, wind speed, soil temperature and soil water data from an unmanipulated shrub patch itexheathmicroclimate - Hourly air temperature, humidity, wind speed, soil temperature and soil water data from the control area of the ITEX dry heath study site itextussockmicroclimate - Hourly air temperature, humidity, wind speed, soil temperature and soil water data from the control area of the ITEX tussock tundra snowfence study site NF_soil_temp_and_soil_water_08 - This is a study of how soil temperatures at 10 cm and soil moisture change across the summer at our IPY snow fence site Plant_mineral_nutrition_2007_and_2008 - This is a study of how shrub-betula nana leaf 15N, 13C, %N, %C varies over the course of the summer in 2007 and 2008.
