*Each of the 6 rivers will be sampled 2X in 2003, 7X in 2004, 7X in 2005, and 2X in 2006
*Samples will be collected during all seasons, with at least 1 sample per year (2004 and 2005) through the ice

WATERSHEDCHAMP: PARTNERS will obtain biogeochemical data, including isotopic tracers, that will aid in understanding of catchment hydrology
LAII/PACTS: PARTNERS will help close nutrient and carbon budgets for the arctic terrestrial zone
COASTAL ISSUESLSI: PARTNERS will provide estimates of biogeochemical fluxes (nutrients, carbon, sediments, etc) to the arctic coastal zone
ARCTIC OCEAN ISSUES OAII/SBI: PARTNERS will determine river tracer concentrations and fluxes needed to better follow riverine freshwater in the Arctic Ocean
ENTIRE ARCTIC SYSTEMARCSS/SEARCH: PARTNERS will provide data linking terrestrial and oceanic domains, and establish contemporary baseline of
biogeochemical fluxes needed to detect future changes
