(Clarendon PressWiley Periodicals, Inc., 2009-03)
Relative effects of wind stress curl, topography, and stratification on large‐scale circulation in Lake Michigan

Widespread and Persistent Deposition of Iron Formations for Two Billion Years
(ElsevierWiley Periodicals, Inc., 2019-03-28)
Composed of chemical precipitates rich in iron and silica, Precambrian iron formations from marine sedimentary records may reveal biogeochemical processes over the first half of Earth history. The limited record of early ...
P-wave velocity of weathering profiles from a basalt climosequence: Implications for weathering on the mechanical properties of the critical zone
(2016-01-20)
We characterize the critical zone structure across a basaltic climosequence in Kohala, Hawaii from shallow seismic refraction data. First-arrival P-waves surveys were tomographically inverted from an active source to create ...
Assessing the role of the San Andreas fault in controlling the spatial distribution of erosion rates in the Transverse Ranges, Southern California
(2013-05-17)
In considering erosion rate controls, previous work has focused primarily on the geomorphic factors; here tectonic controls, particularly seismic shaking, are additionally considered, given the growing recognition that ...
A coupled geochemical and biogeochemical approach to characterize the bioreactivity of dissolved organic matter from a headwater stream
(Academic PressWiley Periodicals, Inc., 2014-08)
The bioreactivity or susceptibility of dissolved organic matter (DOM) to microbial degradation in streams and rivers is of critical importance to global change studies, but a comprehensive understanding of DOM bioreactivity ...
Temporal evolution of the transpolar potential after a sharp enhancement in solar wind dynamic pressure
(Wiley Periodicals, Inc., 2008-01)
Characterization of site‐specific GPS errors using a short‐baseline network of braced monuments at Yucca Mountain, southern Nevada
(Wiley Periodicals, Inc., 2009-11)
