Introduction
                
Details about individual rivers included in the aggregate analysis of "A pan-Arctic evaluation of changes in river discharge 
during the latter half of the 20th century" are provided as Auxiliary
Material.  Watershed characteristics and average discharge are presented in 
"2006gl025753-ts01.txt" and gauge locations, temporal coverage, and 
correlations between upstream and downstream stations for the 10 small to 
medium sized Eurasian arctic rivers (less than 60 km3/y) included in the 
analysis are presented in "2006gl025753-ts02.txt".  

1. 2006gl025753-ts01.txt Watershed location (continent), outlet, catchment 
area, and average 1964-2000 discharge for the 72 rivers included in this 
study.  EA = Eurasia, NA = North America, AO = Arctic Ocean, HB = Hudson Bay, 
JB = James Bay, UB = Ungava Bay.
1.1 Column "river" identifies river name.
1.2 Column "Continent/Outlet" identifies the continent that the river flows
from and the location of its outlet
1.3 Column "Catchment Area (km2)" reports area of the catchment drained by
each river.
1.4 Column "Average Q (km3/y)" reports average discharge.           

2. 2006gl025753-ts02.txt Gauge locations, temporal coverage, and 
correlations between upstream and downstream stations for the 10 small to 
medium sized Eurasian arctic rivers (less than 60 km3/y) included in the
analysis.  Where discharge at upstream and downstream locations is reported, 
regression relationships between the stations were used to estimate 
downstream discharge during missing years.  Rivers where there was no data at 
either location in some years are identified by the following symbols: 
*no data for 1994, **no data for 2000, #no data for 1983-1987, 1990-1992, 
##no data for 1992, +no data for 1996, 2000.
2.1 Column "River" identifies river name.
2.2 Column "Location of Gauge" identifies location of discharge measurement
at downstream and upstream stations.
2.3 Column "Temporal coverage" reports years of discharge measurements at 
the downstream and upstream locations shown in column "Location of Gauge".
2.4 Column "Corr" identifies r2 values for correlations between discharge
at upstream and downsteam locations (where applicable).
