In the Arctic, where tundra streams often freeze solid in winter, spring locations might provide an overwintering refuge for fish and other aquatic animals. Today’s journey took us to the lower Oksrukuyik Creek, where we visited two sites with potential to overwinter fish: Oks 2.5 and OLAS. With the sun glitteringly reflected off the pristine white snow, we launched our snow machines from the Dalton Highway in search of fish under ice. Fish antennas help track individually tagged fish as they move through the aquatic landscape. Although currently encased in ice, we furnished the Oks 2.5 antenna with fresh batteries, tuned the antenna and left it poised to capture fish movement once the river flow freely again. Although we found no open water to support fish overwintering at Oks 2.5, we found not only open water, but fish at the OLAS site! We found the OLAS site in 2013, but today we discovered fish at this site, as well as open water. Very cool.
