1-minute Mesoscale Domain Sector GOES-18 (GOES-West) “Red” Visible (0.64 µm) images (above) showed areas of bright sun glint off the open (ice-free) water in the Chukchi Sea — just off the coast of Alaska, from the Bering Strait to near Utqia?vik — around 1 AM local time on 08 June 2024. Note how there was also sun glint off the open water of leads within the sea ice, as well as inland rivers/lakes across northwestern and northern Alaska.

During the subsequent daytime hours, a sequence of VIIRS Snowmelt RGB images sourced from GINA and displayed using RealEarth (below) provided a more detailed view of the sea ice and the areas of inland snow cover (shades of cyan to light blue), in contrast to the areas of open water (dark blue) off the Alaskan coast.
