Research

  • Seasonality of Circumpolar Tundra: Ocean and atmosphere controls and effects on energy and carbon budgets
    • A synthetic view of changing seasonality across the land/ocean boundary of the Arctic Ocean.
  • Synthesis of Arctic System Science: Greening of the Arctic
    • Remote sensing, maps, climate studies and models to address the question of how terrestrial vegetation of the Arctic responds to climate change.
  • Greening of the Arctic
    • Documenting the rapid and dramatic changes to terrestrial vegetation that are expected to occur across the circumpolar Arctic as a result of climate change is a key goal of the IPY.
  • NASA Yamal Project
    • The overarching goal of the Yamal portion of the GOA project is to examine how the terrain and anthropogenic factors of reindeer herding and resource development combined with the climate variations on the Yamal Peninsula affect the spatial and temporal patterns of vegetation change and how these changes are in turn affect traditional herding of the indigenous people of the region.
  • Toolik-Arctic Geobotanical Atlas
    • The Toolik-Arctic Geobotanical Atlas (TAGA) is a web-based multi-scale collection of geobotanical maps and related material that focuses on research sites at the Toolik Field Station and Imnavait Creek, Alaska, but also covers the Kuparuk River Basin, northern Alaska, Arctic Alaska, and the Circumpolar Arctic.
  • North American Arctic Transect
    • The North American Arctic Transect addresses the Greening of the Arctic (GOA) themes of Current State, Change, and New Frontiers.
  • Biocomplexity of Frost Boil Ecosystems
    • This project seeks to understand the complex linkages between biogeochemical cycles, vegetation, disturbance, and climate across the full summer temperature gradient in the Arctic in order to better predict ecosystem responses to changing climate.
  • Circumpolar Arctic Vegetation Map
    • The Circumpolar Arctic Vegetation Map (CAVM) project is an international effort to map the vegetation and associated characteristics of the circumpolar region, using a common base map.
  • Arctic Transitions in the Land-Atmosphere System
    • This study was part of the Arctic Transitions in the Land-Atmosphere System (ATLAS) project, which studied the large-scale variations in trace-gases, energy, and water.
