Primary Research Objectives

Quantify long-term trends in lake and/or stream water, precipitation, and snowpack hydrology and chemistry.

Examine the role of vegetation, surface organic layers, and shallow soils in modifying precipitation solute concentration and flux.

Define terrestrial-aquatic linkages for nutrient and energy transfers.

Examine the effects of global change, especially climate and precipitation, on terrestrial carbon and nitrogen cycles.

Quantify terrestrial production of dissolved organic carbon and nitrogen, and its input to the aquatic ecosystem.

Quantify trends in above-gound vegetation diversity, biomass, and nutrient content.

Quantify long-term trends in terrestrial and aquatic ecosystem production, and define the major processes accounting for observed changes.
