Overview of Recent Work
Here's a link to my current CV.
Here are some web pages and documents which summarize our work:
A 4D representation of some of our indiviual-based fish (pollock) model results for various years. The model is centered near Kodiak Island, AK. In the above frame Kodiak Island is on the right and Alaska is to the left; we are looking northeast into Shelikof Strait. These are animated VRML worlds which *should* run on most PC and Mac web browsers (if not try installing the Cortona Viewer). Fish are represented as spheres which move through time, with modeled seafloor bathymetry rendered as a 3D surface. Click on the above frame to open this world. Here also are some representative fish worlds (in black and white) for 1978 1987 1988 1991 1994
