    As activity in the Arctic increases, so too does the need for accurate sea ice models that are of higher resolution and forecast farther into the future. USNIC and its many partners are central to this work. See this article to learn more!

  3. Some years, like this one, an "ice bridge" forms in Nares Strait in the Canadian Arctic. This stops old ice flowing into Baffin Bay until it fractures in the spring. We use SAR and Infrared imagery to help find features like this.

  6. Although we can't measure ice thickness directly from SAR imagery different ice thicknesses show up as different textures. Young ice in the top half of the image (Jan 27) and first-year ice in the bottom half.

    We use "egg codes" to describe the concentration, stage of development (age) and form (floe size) of and lake ice on our ice charts. This diagram helps explain what they mean. To learn more, consult the Manual of Ice (MANICE)

  9. SAR imagery allows us to see through clouds. Sometimes, like in this Radarsat-2 image from January 21, 2020, wind shifts and airmass changes can be observed over open water.

  12. Because of how shallow Lake Erie is it tends to form ice and melt ice quickly. By the second week in January ice conditions should be increasing rapidly. For the first time since 2007 we are observing no ice cover on the lake.

  15. Sea ice can take many different textures from satellite. The fast ice in Lake Melville has ship tracks, sea ice, and freshwater ice in this Sentinel-1 radar satellite image.

  16. Every year on January 1 our charts change from containing second-year ice (8.) and multi-year ice (9.) to containing old ice (7.). The ice didn't dissapear, just changed names. (Table 5.2, note 3)

  17. We use different satellites to monitor movement. Here is 5 days of microwave satellite images showing ice movement in the Canadian . Movement due to winds and current.
