Helicopter electromagnetic data map ice thickness at Mount Adams and Mount Baker, Washington, USA

Ecological Zones: A Hike Up Mount Washington

Vegetation patterns 25 years after the eruption of Mount St. Helens, Washington, USA.

In 2004, we surveyed the vegetation on Mount St. Helens to document changes since 1992. We asked how communities differentiate and if they develop predictable relationships with local environments. We sought evidence from links between species and environment and changes in community structure in 271 250-m(2) plots. The habitats of the seven community types (CTs) overlapped broadly. Ordination ...

Turbulence Monitoring at Mount John

In this paper we present preliminary results of a turbulence monitoring campaign at the Mount John University Observatory using a bread-board based SCIDAR (SCIntillation Detection And Ranging) system. Simultaneous SCIDAR and generalised SCIDAR data are captured and used to quantify the turbulence at the site. Initial results, including estimates of key turbulence parameters, are presented and d...

A model for the magmatic–hydrothermal system at Mount Rainier, Washington, from seismic and geochemical observations

Mount Rainier is one of the most seismically active volcanoes in the Cascade Range, with an average of one to two high-frequency volcano-tectonic (or VT) earthquakes occurring directly beneath the summit in a given month. Despite this level of seismicity, little is known about its cause. The VT earthquakes occur at a steady rate in several clusters below the inferred base of the Quaternary volc...
