Ice Observatories
Webcams In addition to providing a visual impression of the sea-ice conditions off oberservatoy locations, webcam images establish a longer-term record of key dates in the seasonal evolution of the sea-ice cover, such as: onset of fall ice formation, formation of a stable ice cover, onset of spring melt, appearance of melt ponds, beginning of ice break-up in early summer, removal or advection of sea ice during the summer months. The webcam in Barrow is installed atop a 4-story building in downtown Barrow (71° 17′ 33″ N, 156° 47′ 18″ W). The camera is looking approximately NNW. The webcam in Wales is mounted on top of the Kingikmiut School at the base of Cape Moutain. The camera is looking approximately WNW. On a clear day, both Fairway Rock and the Diomede Islands are visible. Both webcam images are updated online every 5 minutes. Radars
Listen to Andy Mahoney's Straight Science Talk on the history of the Sea ice radar and how it works. Iñupiaq Sea Ice Knowledge - Project JukeboxProject Jukebox at UAF (Karen Brewster and collaborators) compiled interviews conducted with Iñupiaq sea ice experts from Barrow and neighboring communities, drawing on research by Matthew Druckenmiller, Dyre Oliver Dammann, Lewis H. Shapiro and others from our research group. The interviews and additional information is available at the Project Jukebox website: Project Jukebox Additional informationA detailed overview of the various components and research objectives of the Barrow Sea Ice Observatory are presented in the following paper: Druckenmiller, M.L.; H. Eicken; M. Johnson; D. Pringle; C. Williams (2009) Towards an integrated coastal sea-ice observatory: System components and a case study at Barrow, Alaska.
