We would like to announce the availability of CT and MRI 2D and 3D images of a wide variety of marine mammals as well as other species through our laboratory website http://csi.whoi.edu. The site also provides background information on the scanning methods, our lab design, downloadable copies of related publications, and links to related websites. Ultimately, we will be posting full anatomical series for most species, but at present have only representative images of most species available in our archives. If you are interested in images of a species that is listed for the collection but is not available on the site, please contact us, and we will try to arrange for the image set to be provided on DVD or via our ftp server. This site is under development, and we therefore welcome your comments or suggestions on its content and operation. Darlene Ketten, Senior Scientist, WHOI dketten@whoi.edu
