Chuck's research interests include the modern and ancient formation of sedimentary strata in continental-margin environments. Ongoing research includes coastal areas near the Amazon and Mekong Rivers, tidewater glaciers in Patagonia, and the impacts of dam removal from the Elwha River. Other recent studies have been completed in New Guinea-Australia, the Mediterranean, and off Antarctic and Alaskan glaciers.

Sarah studies rivers and how they change over time, specifically looking at controls on river incision rates and the formation of bedrock river terraces. Her work focuses on Pacific Northwest Rivers such as the Willapa, Satsop, Nehalem, and Teanaway Rivers.
Geomorphology
Teaching AssistantEarth & Space Sciences
PhD student
Jonathan studies how landscapes change through time, from the glaciers and rivers that sculpt mountain ranges to the individual rocks that line the bed of rivers. Locally his work focuses on rivers draining Mount Rainier and the deglaciating Cascade Range.
Topics to be covered
Earth Surface Processes
Mountains Rivers Beaches Ocean
Holistic view, including: 1) Solid Earth2) Atmosphere
Linkages of all these will be an emphasis of the course.
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 could rise.
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:
Centraliarainfall landslides flooding
New Orleans/Galvestonhurricane wind storm surge
Indonesia / Japanearthquake submarine landslide tsunami
emphasis on understanding fundamental processes, but shock and awe will come with some examples
(the flip side = these same environments produce most natural resources)
Rivers and beaches are part of sediment transfer systems.
• What forms them?
• What are the processes that maintain them?
• Why are there different types of rivers and beaches?
• What controls their distribution across the Earth surface?
We’ll use 1 equation in this class
I - O = S
Input minus output equals change in storage.
Also known as conservation of mass
means change in something

Sample bottom sediments, measure water salinity and temperature, and map bathymetry
Bring clothes for bad weather (wet, cold, windy, dirty) -- even if it doesn’t seem like you’ll need them!
Bring your lunch and beverages, also
Details of Nisqually trip coming next Tuesday.
Field Trip Tips
Please Note
The course puts a high premium on the learning that comes from field observations.
Participation in field trips is required to get credit for field trips. There are no make-up trips or alternate work that can be substituted for the trips.
If you miss one, your options are: For 3-credit registrants:1) you can take a zero for the field trip;2) you can drop the course.
For 5-credit registrants:1) you can drop to 3 credits;2) you can take a zero in the missed trip;3) you can drop the course.
If you need a note explaining your absence from other classes, please contact Chuck at least a week before the trip. (for next Th, need to know now)
Info needed:name of instructor their email address course name and number
Contact Jonathan ([email protected]) to sign-up for Field Trip A on either 8 or 15 Oct.
Reservations will be limited for each day, and will be accepted on a first-come basis.

A different way of seeing
landscapes and seascapes
The Big Picture = The Rock Cycle
Material eroded from mountains enters streams and rivers and is
delivered to coastal environments, from where it is moved to deeper sedimentary
basins that get shoved back into mountains through processes of
rock uplift.
The Rock Cycle
The Rock Cycle
Erosion in the Rock Cycle
What we see as rivers and beaches are rest stops for sediment moving through
the eroding half of the rock cycle.
