Research Themes
Cryosphere 
      How is climate change affecting the mass balance of the polar ice sheets? Can we use space-borne remote sensing to quantify ice flow in the polar ice sheets? Is the Arctic hydrological cycle accelerating? What is the freshwater budget of the Arctic Ocean drainage basin?
      Faculty/Research PI’s: Dibb, Fahnestock, Lammers, Shiklomanov, Twickler, Wake
      Research Methods: modeling, data synthesis, remote sensing, field studies
      What are the impacts of human-induced changes in land use and land cover on the climate system? How reliably can we detect land-use/land-cover change from space?
      Faculty/Research PI’s: Frolking, Li, Ollinger, Palace, Rubin, Xiao
      Research Methods: remote sensing, modeling, field studies, data synthesis
      Is the Arctic hydrological cycle accelerating? What regions of the world will suffer from water shortages in the coming decades? What is the freshwater budget of the Arctic Ocean drainage basin? 
      Faculty/Research PI’s: Lammers, Prusevich, Shiklomanov, Wollheim
      Research Methods: modeling, data synthesis, remote sensing
      What biogeochemical and physical processes control the composition and variability of seafloor hydrothermal vents (hot springs)? What are the linkages between the chemistry of the fluids and both the surrounding biological communities and the chemistry of the ocean? How do freshwater ecosystems process nutrient inputs, and how much gets delivered to coastal oceans?
      Faculty/Research PI’s: Wollheim
      Research Methods: field studies, modeling, remote sensing, data synthesis
      How are forests responding to increased nitrogen inputs? What is the role of peatlands in the Earth’s carbon budget? What is the role of the Amazonian forest in the Earth’s climate system? How much do croplands contribute to atmospheric greenhouse gases, and what are possible mitigation strategies? How are forests responding to increased nitrogen inputs?
