UAA Ph.D. student leads Arctic research expedition down Alaska's Colville River
by Kathleen McCoy |
For the next two weeks, a Ph.D. student with UAA's Environment and Natural Resources
Institute (ENRI), Ken Tape, along with ENRI undergraduate research assistant Ty Spaulding
and two other colleagues are floating the Colville River from Impnavik to the Colville-Anaktuvuk
River confluence.
The purpose of their trip is to survey the landscapes that adjoin the river and to conduct research to examine why large stands of woody shrubs are expanding in some locations but not in others. The group will measure soil chemistry and soil water properties in several expanding and non-expanding shrub islands and will collect soils and vegetation for nutrition and integrative leaf physiology measurements.
