Source mechanics for monochromatic icequakes produced during iceberg calving at Columbia Glacier, AK
Shad O’Neel, W.T. Pfeffer
2007, Geophysical Research Letters (34)
Seismograms recorded during iceberg calving contain information pertaining to source processes during calving events. However, locally variable material properties may cause signal distortions, known as site and path effects, which must be eliminated prior to commenting on source mechanics. We applied the technique of horizontal/vertical spectral ratios to passive seismic...

Weirs: Counting and sampling adult salmonids in streams and rivers
Christian E. Zimmerman, Laura M. Zabkar
2007, Book chapter, Salmonid field protocols handbook: techniques for assessing status and trends in salmon and trout populations.
Weirs—which function as porous barriers built across stream—have long been used to capture migrating fish in flowing waters. For example, the Netsilik peoples of northern Canada used V-shaped weirs constructed of river rocks gathered onsite to capture migrating Arctic char Salvelinus alpinus (Balikci 1970). Similarly, fences constructed of stakes and...
