Sampling Schedule
*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

PARTNERS: Links to Arctic Research Programs
WATERSHED
CHAMP: 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 ISSUES
LSI: 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 SYSTEM
ARCSS/SEARCH: PARTNERS will provide data linking terrestrial
and oceanic domains, and establish contemporary baseline of
biogeochemical fluxes needed to detect future changes
