Mechanisms and feedback consequences of shrub expansion following long-term increases in winter snow depth in northern Alaska: a legacy for IPY

Data Access:

  • 2007_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.

  • 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.
