		Sea Ice Webcam The webcam image above is taken from atop a 4-story building in downtown Barrow, Alaska. The camera is looking approximately NNW and updated every 5 minutes. Click image, or here for a larger view. Location: 71° 17′ 33″ N, 156° 47′ 18″ W. Contact: Jeremy Harbeck
		Sea Ice Radar This radar image is from a radar mounted on a 4-story building in downtown Barrow near the beach. It is updated every 10 minutes, through night and day. Green is the coastline. White marks show objects that reflect the radar signal - including buildings and rough sea ice. Animations of last 24 hours and full-size image. Animations of ice break-out events 2004, 2006, 2007.
		Barrow sea ice break-up outlook Our take on sea ice break-up in Barrow based on regional weather and forecast. Plots are updated daily. This outlook is geared toward ice in the Chukchi Sea North of Barrow (NARL and North) rather than ice directly offshore downtown Barrow. Contact: chris.petrich@gi.alaska.edu
		Sea Ice and Sea Level Station Operating 15 January–12 June 2009 on land-fast first-year Chukchi Sea ice, about 1 mile offshore. Location 71.36655° N, 156.54140° W, similar to previous years (GPS co-ordinates of previous years). Measures snow and ice thickness, local sea level, water-ice-snow-air temperatures. Real-time data are here. Data Archive 2009 results 2008 results 2007 results 2006 results 2009 location: 71.36655° N, 156.54140° W. Contact: chris.petrich@gi.alaska.edu
