Dendrohydrological Reconstruction Of North Fork Nooksack River August Streamflow From Subannual Mountain Hemlock Ring-Widths, Cascade Mountains, Washington State, Hannah Lagassey
WWU Graduate School Collection
Climate warming is driving changes to snowpack and streamflows in snow and ice-driven systems throughout the world. To better understand present and future conditions, we need to examine conditions prior to the onset of climate warming. Tree ring records are used widely to reconstruct pre-instrumental climate and hydrological records. Some locations are more conducive to this methodology than others, however, and moisture-rich environments such as the west slopes of the Cascade mountains continue to present challenges to effective hydrological record reconstruction. Previous researchers working in this environment have employed several techniques in response to this problem, which require integrated dendrochronological …
Dendrochronological Assessment Of The Easton Glacier's Terminus Position Over The Last 150 Years, Monica A. Villegas
Dendrochronological Assessment Of The Easton Glacier's Terminus Position Over The Last 150 Years, Monica A. Villegas
WWU Graduate School Collection
The Easton glacier on Mt. Baker, Washington has been the focus of several studies looking at ecological succession, glacier recession, and glacier mass balance. Several of these studies have noted a gap in the literature regarding the Easton glaciers terminus position in the early twentieth century. This study has refined the glacier's terminus position by using dendrochronological methods and identified the latest Little Ice Age end moraines. A chronology of the Easton glaciers terminus position overtime was created showing its recession and advancement since 1879. The rates of recession and advancement were calculated during this time highlighting the unpredictable behavior …

Dendrochronology Of Seaside Juniper (Juniperus Maritima), Dustin Gleaves
WWU Graduate School Collection
Seaside juniper (Juniperus maritima) is a recently discovered tree species endemic to the Salish Sea region and is an as yet unutilized dendrochronological resource. This study reports the first dendrochronological investigation of the species. We sought to determine if Seaside junipers are capable of crossdating, a requirement for consideration as a dendrochronology study species, and to identify correlations between instrumental climate records and radial growth to determine climate-growth response. We collected tree core samples from Seaside juniper in five sites throughout the San Juan Islands and nearby mainland. Samples collected from one of five sites successfully crossdated. Bootstrapped …
