Annotated sea ice graphics
ACCAP Climate Specialist Rick Thoman creates and shares these graphics on social media to illustrate current sea ice conditions off Alaska.
The latest image is at right. Rick also posts these images on AAOKH's Facebook page.
Each spring, Utqiaġvik hunters build trails across the shorefast sea ice to access whale hunting sites. These trails are mapped to ensure safer travel.
Utqiaġvik & Nome sea ice radar
Images are acquired by a marine radar positioned near the coast, and are updated every 4 minutes. Past imagery and annotations are available.
Atmospheric satellite imagery
Infrared (IR) and DayNight bands available. IR is used for cloud and other atmospheric feature identification. DayNight can show clouds at night if there is enough moonlight.
ACCAP Sea Ice Graphics
Produced by ACCAP Climate Specialist Rick Thoman, these maps and graphs illustrate sea ice extent, concentration, and other features.
ACCAP Sea Surface Temperatures
Sea surface temperatures (SST) affect weather patterns. Produced by ACCAP Climate Specialist Rick Thoman, these maps and graphs illustrate SST off Alaska.
ACCAP Air Temperature Graphics
Produced by ACCAP Climate Specialist Rick Thoman, these maps and graphs illustrate air temperatures, warming and cooling trends, and more.
Arctic-wide changes in sea ice
Monthly images show sea ice extent with an outline of a 30-year median extent for that month. Daily extent images show ice extent at concentrations > 15% for a given day.
Sea Ice forecasts and analyses
Map-based forecasts and analyses of sea ice extent and concentration off Alaska. Includes text-based 3-month sea ice outlooks.
NASA Worldview imagery
Stunning satellite imagery of Alaska's coast, snow and ice cover, and more. Interactive timeline slider lets you see past images, and pan/zoom the image for more detail.
