This web site was authored by Don Perovich, Tom Grenfell, Bonnie Light, Bruce Elder, Jeremy Harbeck, and Kelly Everhart. It contains the field data from studies of "Morphological and optical characteristics of the summer Arctic sea ice cover" conducted during the 2005 Healy-Oden TransArctic Expedition (HOTRAX). It is  intended to provide background on the program, an overview of our observations, and data and metadata. Logs and photographs from the transect are also provided.

Acknowledgments: This project was funded by the National Science Foundation's Arctic Natural Science Program. We thank the crew of the United States Coast Guard Icebreaker Healy for their generous and expert assistance during the expedition.
