NASA Terra Captures June 3 Bering Sea Ice Melt as Yukon Runoff Spreads Sediment

1 articles · Updated · Science@NASA · Jun 22

Summary

  • June 3 MODIS images from NASA's Terra satellite showed the Bering Sea in early summer transition, with sea ice broken into small fragments and nearing complete melt off Alaska.
  • Snowmelt-fed rivers were simultaneously flushing sediment and organic material into coastal waters, especially around the Yukon Delta, where brown plumes spread after river ice breakup and seasonal runoff.
  • Saint Lawrence Island—about 150 miles south of the Bering Strait—still had pack ice along its northeast coast, while surrounding floes curled into wispy patterns shaped by winds and currents.
  • False-color imagery also highlighted green tundra and marsh vegetation, dark blue ice-free rivers and thermokarst lakes, underscoring how rapidly Alaska's coastal landscape shifts at the start of summer.
