Chuck's research interests include the modern and ancient formation of sedimentary strata in continental-margin environments, and the effects of physical and biological oceanic processes on sedimentary characteristics. Ongoing research includes coastal areas of New Guinea-Australia, the Mediterranean, and US west coast. Other recent studies have been completed at the mouths of the Amazon River, Asian rivers, and off Antarctic and Alaskan glaciers.

Marine Geology & Geophysics
Assistant Professor, School of Oceanography
Ph.D, University of Minnesota
Ben’s research interests generally involve processes and deposits associated with sedimentary systems found both in and out of oceans—from mountain-front alluvial fans to deep-sea channels. In particular, he studies the relationship between active geomorphic processes and their rock record. Current research includes outcrop studies in Utah and South Africa, and physical experiments simulating deltaic and deep-water sedimentary processes.

In order for there to be mountains, rocks must be uplifted above sea level.
If uplift continued unopposed there would be no limit to how high mountain ranges can get.

Erosion counter-balances rock uplift

Mountain streams receive material from hillslopes and transport it to
rivers

Rivers transport material to the coast

Nearshore processes redistribute sediment along beaches and coastlines

Types of beaches reflect differences in sediment sources and transport

Earth Surface = where we live
Recent Dramatic examples:

but shock and awe will come with some examples

Geomorphology
Professor, Dept of Earth & Space Sciences
Ph.D., University of California, Berkeley
Dave Montgomery studies the evolution of topography and the influence of geomorphological processes on ecological systems and human societies. His work includes studies of the evolution and near-extirpation of salmon, fluvial and hillslope processes in mountain drainage basins, the evolution of mountain ranges (Cascades, Andes, and Himalayas), and the analysis of digital topography of Earth and Mars.
