CSI 803 Related Links

You can check out a draft of the term paper on the web: Term Paper. For the CSI 803 Term Project I am proposing to work with another student in class, Gary Page. A detailed outline of our project can be found at this web page . The original preliminary abstract of our project follows: The website called "Flow Dynamics of a Wide Arctic Canyon" is the introductory web page to research conducted by Dr. Sergio Signorini, which may be used as a basis for the CSI 803 term project. Dr. Signorini developed a model of the ocean current flow in the vicinity of Barrow Canyon. Dr. Signorini's results are going to be published in the Journal of Geophysical Research. Some of his results are depicted in a static plot which he has at the following URL: http:// . Dr. Signorini has completed a supercomputer model run on the Cray YMP at the Arctic Regional Supercomputer Center in Alaska whose data output he has courteously provided us for this term project effort. The output will be examined and perhaps converted to a format that can be displayed by the freeware from Wisconsin known as Vis5D. Vis5D is a powerful package available on UNIX machines for displaying scientific data. Using this package we hope to develop an animation based on the model output data and demonstrate how best to display such datasets.

Here's a link to the CSI 801 homepage . Here are links to pages related to the term project which dealt with the discovery of microbial life on a meteorite with Mars origins and my team's efforts to simulate the temperature conditions on Mars billions of years ago and how that would effect the development of life (particularly the size of the microbes) at that time.

Here are links to homepages produced by other team members:
