Utilizing dendrohydrology to analyze relationships between plant growth and available soil water in the Marcell Experimental Forest
Salli Dymond, University of Minnesota, PhD Candidate
Salli Dymond, a PhD candidate studying forest ecohydrology at the University of Minnesota, conducts research that explores the relationship between available soil water and forest productivity in northern forests, specifically at the Marcell Experimental Forest. To investigate these relationships, Dymond utilizes a variety of different techniques including, soil water modeling, long-term soil moisture datasets, dendrochronology (tree-ring dating), and stable isotopes. 
 

 
Investigation the impact of soil erosion in Ethiopia and cloud forests in Honduras for improved water quality management
Christian Guzman, Cornell University, PhD Candidate
 
 
Christian Guzman, a doctoral student at Cornell University in the Biological & Environmental Engineering Department, has conducted previous research in watersheds in the Ethiopian Highlands to investigate hydrological and sediment concentration responses to precipitation events. For Guzman’s Pathfinder-funded research, he traveled to Honduras to conduct comparative watershed research in two watersheds in the town of Güinope. The difference in percentage forest cover and vegetation between the rural watersheds in Honduras and Ethiopia will allow Guzman to better understand the differences in watershed dynamics and hydrological processes.

 
Hydro-chemistry and stable isotope composition of Ugandan waters
Scott Jasechko, University of New Mexico, PhD Candidate

Scott Jasechko, a doctoral student at the University of New Mexico in the Department of Earth and Planetary Sciences, recently completed a country-scale assessment of inorganic trace and major ion chemistry and stable oxygen and hydrogen isotopes in Ugandan surface and ground waters. As a 2012 Pathfinder Fellow, Jasechko had the opportunity to lead a hydrological invesitgation at a new field site and conduct the first regional analysis of surface and ground water sources in Uganda with the collection of more than 300 water samples.

A bipolar comparison: understanding black carbon impacts on snow-melt hydrology and water quality in Longyearbyen, Svalbard
Alia Khan, University of Colorado-Boulder, PhD Candidate
 
 
Alia Khan, a doctoral candidate at the University of Colorado, Boulder in the Institute of Arctic and Alpine Research, conducts research in extreme conditions. As a recipient of a 2012 CUAHSI Pathfinder Fellowship, Khan traveled to Longyearbyen, Svalbard, an island in the Arctic Circle governed by Norway, to conduct field research. Khan’s primary research focuses on quantifying human impacts in the McMurdo Dry Valleys by studying black carbon (BC), a product of incomplete combustion of fossil fuels such as coal, in the dissolved phase in water in the lakes of the Dry Valleys.

 
A field component in a multi-method study to understand why spring snowmelt is occurring sooner
John Mioduszewski, Rutgers University, PhD Candidate
 
John Mioduszewski, a doctoral candidate at Rutgers University in the Department of Geography, is focused on understanding why snow has been melting sooner across much of the Northern Hemisphere lands, within the uncertainty range of inter-annual and regional variability. Mioduszewski is addressing this problem from multiple scales, from hemispheric down to a regional scale in Northern Canada.
