"Pink Salmon
Returns at Solomon Gulch Hatchery"
Users often combine Golden Software products to produce their final project. Dr. Richard Crawford, of the
Prince William Sound Science Center
(PWSSC), used a combination of Surfer, Voxler, and Grapher to complete his study of “Enhancing in-house assessment of pink salmon returns at Solomon Gulch Hatchery” in Alaska.
A full PDF of Richard’s research can be found at:

As Richard describes, “We explored the use of three-dimensional modeling for studying fish distribution and behavior at the Solomon Gulch Hatchery in Prince William Sound by combining traditional fisheries acoustics techniques with the novel use of Geographic Information System (GIS) modeling and graphical visualization. The goal was to gather information to help optimize escapement for brood stock while maximizing the opportunity for harvesting the surplus for cost recovery and the open fishery. Golden Software products Surfer, Voxler and Grapher were perfect for the task.”
VOXLER IMAGES:
Isosurfaces were created in
Voxler to display the volume visualization for the schools of fish. This
allows the true shape of the fish schools to be displayed.
