Overview of Recent Work [Bar]

I work with other physical oceanographers and biologists on models of circulation, plankton and fish dynamics in the Gulf of Alaska and the Bering Sea, as part of the Ecosystems and Fisheries-Oceanography Coordinated Investigations (EcoFOCI). Support for much of this work has come from the Northeast Pacific GLOBEC program, the Fisheries and the Environment (FATE) program, the Bering Ecosystem Study (BEST) and Bering Sea Integrated Ecosystem Research Program (BSIERP), and the the Gulf of Alaska Integrated Ecosystem Research Program (GOAIERP). A related body of work centers on low-cost immersive stereo (3D) visualization techniques, supported mainly by NOAA's High Performance Computing and Communications (HPCC). 

Here's a link to my current CV.

Here are some web pages and documents which summarize past work: 

  • A short movie loop of Northeast Pacific modeling results
  • A summary of our work on visualization for fisheries oceanography. The original publication is available at www.springerlink.com
  • A very dated general overview of some biophysical models and their coupling, circa 1996.  
  • Modeling efforts for the wider Coastal Gulf of Alaska (supported by GLOBEC) (with animations), and a paper describing our findings.
  • Previous nested models of the North Pacific, to address GLOBEC, Sea Lion, and Bering Sea issues.
  • A Live Access Server providing interactive access to nested model output for the Northeast Pacific.
  • A multiyear index of flow through Shelikof Strait, derived from numerical model output, and a description of the Live Access Server.
  • Modeling activities for the Southeastern Bering Sea (SEBSCC) (with animations and virtual reality),and a paper describing our findings.
  • A report to the North Pacific Research Board on Evaluation of ocean circulation models for the Bering Sea and Aleutian Islands.
  • Modeling results for the Northern Gulf of Alaska (FOCI) (with animations of salinity field), and a presentation on eddy statistics
  • A spawning experiment for FOCI using coupled biophysical models (with animations). 
  • A paper which describes methods of physical-biological coupling
  • An extended abstract (circa 1996) describing an early approach to boundary conditions for a regional model which includes tidal and subtidal flows. Note: this has been superseded by one-way nesting with the Regional Ocean Modeling System (ROMS)
  • Low-cost stereo virtual reality for oceanography (what you can do with two eyes, a PC, and a few hundred dollars - or, for a bit more, what you can do with two projectors and polarized lenses)
  • Low-cost immersive teleconferencing for collaborative science (how to confer with your colleagues in 3D using the Personal Access Grid and multiple webcams)
  • Immersive viewing of ocean data in Google Earth. Examples of this work include the following kmz files, which represent ocean temperatures in the western, central and eastern Gulf of Alaska:
  • Virtual Reality [Bar]

    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

    Also check out our animations of salinity fields for these years, which highlight eddies in this region.

    Other Sample Movies

    Pollock Movement
    Click the image to the left to view a quick sample movie of our individual-based biophysical modeling for FOCI. The moving black dots are representative fish (walleye pollock, Theragra chalcogramma), superimposed on the evolving salinity field for 1989 near Kodiak Island, Alaska. We performed these simulations on the CRAY Y-MP at the Arctic Region Supercomputing Center
    [Pollock Movie]
    Pollock Size
    Another movie of pollock size for 1987 illustrates positions of fish after hatching, with length of individuals (in mm) coded by color. Note how some fish get entrained in eddy features, which limit their dispersion.

    These are short animated gifs. We have experimented with other formats but these are *guaranteed* to run on any web browser
