Fairbanks

Location - Aurora Pond

Aurora Pond is located in the Aurora subdivision of Fairbanks, only 2.3 km as the crow flies from the downtown offices of the Fairbanks North Star Borough School District. Situated by the Johansen Expressway, the pond is actually a gravel pit that flooded after highway construction. It is about 200 m by 200 m in size and the water depth varied between 9.3 m and 17.66 m beneath the ice along the 100 m measurement transect used in 2001-02. Aurora Pond is privately owned and we are grateful to Mr. John Roberts for permission to use it for an ALISON observatory.

The observatory at Aurora Pond was run by a group of home-school families coordinated by Deb Bennett. Deb’s children are Kate and Jack, and they worked with Bonnie and her mother Janlee Irving, and Will and his mother, Mary Calmes.

Their involvement in ALISON can be traced back to a somewhat chilly (-28.8°C ) Sunday, 2 December 2001, when Martin demonstrated ice and snow measurements at Aurora Pond to a group of eighteen Alaska GLOBE Program teachers and the program coordinators. Two of those teachers were Deb Bennett and Todd Hindmann, also an ALISON participant.

Elizabeth Lily ran the site with her two children during the last two years data were collected at Aurora Pond.

Deb subsequently contacted Martin Jeffries to ask if he would be able to give an ice and snow observatory demonstration to a group of home-school parents and children. After a demonstration on 20 February 2002 to about twenty people at Aurora Pond, the Bennett, Irving and Calmes families subsequently met Martin and Shannon Graham each Wednesday to make ice and snow measurements. A competition to estimate the maximum ice thickness was won by Jack Bennett, whose estimate of 0.78 m was identical to the actual value on 17 April.

The measurements made at Aurora Pond in 2001-02 by the home-school group are an important contribution to our knowledge of lake ice and snow variability in the Fairbanks area. The Irving family also made an important material contribution in the form of the inflatable boat that we needed to continue the study at Poker Flat during the 2002 melt season.

Everyone enjoyed their visits to Aurora Pond so much that they asked if they could make measurements all winter of 2002-03. After waiting patiently for the ice to form during a particularly mild fall, the observatory was set up on Monday 18 November 2002.
