The Northern Ecosystems Research for Undergraduates (NERU) program focuses on the impacts of climate change on ecosystems in Northern Sweden. The program is a collaboration between the Univ. of N.H. and the Abisko Scientific Research Station. Read more…

We will not offer a summer 2016 program. New program info. will be posted as funding becomes available. All NSF REU student opportunities are listed on NSF REU program websites.

NERU Research Areas
for Summer 2015
  • Implementing metal and metal isotope analyses to track the progress and impacts of thaw
  • Methane Emissions from lakes and peatlands
  • Using remote sensing to understand changing plant community composition and water surfaces
  • Understanding changing microbial communities across the subarctic landscape
  • Lake vegetation and geochemistry to understand carbon cycling
