| Abstract: |
Isotope values for oxygen and hydrogen in waters provide information as to the source of the water, the climate at the time of collection, and the geographical location of the water source. Climate variations may be indicated in changes in the relationship between deuterium and 18O over an extended period. The sources and proportions of sources of ground water can be determined by isotope analysis.
Rain, well and river waters were analyzed for ?18O and ?D values from LTER and LTTG sites in 2002, and LTER1, LTER2, UP2, and FP3 sites from 2003 on. Deuterium values were not replicable until the latter part of the 2005 field season and so were not reported until August, 2005.

FP1A -- FP1A is located on a low early successional terrace (1.8 - 2 m above winter low river level) adjacent to the Tanana River. Vegetation establishment occurred in 1982 to 1983. Significant bank erosion has occurred since the establishment of the study area, resulting in loss of some study plots.
FP2A -- FP2A is located adjacent to the LTER-2 weather station on a terrace that formed ca 1965.
FP3A -- Mixed Balsam Poplar and White Spruce (Open Populus balsamifera-Picea glauca community)
FP3B -- Mixed Balsam Poplar and White Spruce (Open Populus balsamifera-Picea glauca community)
FP3C -- Mixed Balsam Poplar and White Spruce (Open Populus balsamifera-Picea glauca community)
FP4A -- Mature white spruce

LTER1 -- 100 (LTER1) is the Bonanza Creek Experimental Forest's primary upland weather station. More intensive climate data is collected at this station than the other upland stations.
LTER2 -- LTER2, the second Bonanza Creek Experimental Forest full weather station, was established to monitor the climate of the floodplain region of BCEF.
This site is located adjacent to the Tanana River in BCEF.
UP2A -- Closed Mixed White Spruce - Paper Birch Stand
UP2B -- Closed Mixed White Spruce - Paper Birch Stand
UP2C -- Closed Mixed Aspen - White Spruce Stand
