The multiple-glacial and glaciomarine Quaternary history of the Boston, Massachusetts area has been known generally since the earliest studies of the then newly recognized glacial deposits described by Prof. Louis Agassiz in the late1840’s and fossil marine shells in the drift in the 1850’s. Attention then turned to possible glacial...
A large mantle water source for the northern San Andreas Fault System: A ghost of subduction past
Stephen H. Kirby, Kelin Wang, Thomas M. Brocher
2014, Earth, Planets and Space (66-67)
Recent research indicates that the shallow mantle of the Cascadia subduction margin under near-coastal Pacific Northwest U.S. is cold and partially serpentinized, storing large quantities of water in this wedge-shaped region. Such a wedge probably formed to the south in California during an earlier period of subduction. We show by...

Kelly F. Robinson, Duane R. Diefenbach, Angela K. Fuller, Jeremy E. Hurst, Christopher S. Rosenberry
2014, Journal of Wildlife Management (78) 571-579
Many studies have documented that coyotes (Canis latrans) are the greatest source of natural mortality for white-tailed deer (Odocoileus virginianus) neonates (<3 months old). With the range expansion of coyotes eastward in North America, many stakeholders are concerned that coyote predation may be affecting deer populations adversely. We hypothesized that...

Preslip and cascade processes initiating laboratory stick slip
Gregory C. McLaskey, David A. Lockner
2014, Journal of Geophysical Research B: Solid Earth (119) 6323-6336
Recent modeling studies have explored whether earthquakes begin with a large aseismic nucleation process or initiate dynamically from the rapid growth of a smaller instability in a “cascade-up” process. To explore such a case in the laboratory, we study the initiation of dynamic rupture (stick slip) of a smooth saw-cut...
