This Landsat 9 image of the Strait of Belle Isle, acquired April 8, 2025, uses the shortwave infrared, near infrared, and red spectral bands (bands 6,5,4) to highlight land cover. In this combination, healthy vegetation appears bright green, snow and ice appear in shades of cyan and blue, and water appears dark.
