Tracking Glacier Thickness Changes with Grapher and Surfer

A volunteer effort is using Grapher and Surfer to visualize changes in ice thickness over time at the massive Juneau Icefield which straddles the Alaska-British Columbia border. The icefield contains 24 named glaciers and is an important source of fresh water for northern British Columbia.

The number of Chinook salmon passing the dam is typically displayed as a series of line graphs. Major patterns are easy to discern, but small patterns or seasonal variability is hard to identify.

Using Surfer to Create "Temporal Maps"

Richard Koehler observes the behavior of adult Chinook salmon swimming upstream on the Columbia River with the versatility of Surfer to create a time map using two temporal coordinates.
