The effect of vertical mixing on along channel transport in a layered flow
The Columbia River has a large, biologically productive estuary whose ecosystem depends on the balance of salt and fresh water. Outflow from the river also forms a vast buoyant plume which affects circulation for hundreds of miles along the coast. Both the estuarine salt balance and the initial state of the plume are determined ...
Imaging mid-mantle discontinuities: implications for mantle chemistry, dynamics, rheology, and deep earthquakes
Using teleseismic network data and new signal processing techniques, I investigated mantle structure in the vicinity of subduction zones. The 660-km seismic discontinuity in the Izu-Bonin region is depressed by up to 80 km, indicative of material 1000$\sp\circ$K colder than ambient mantle. A broad depression of the discontinuity ...
