A silver swath of sunglint surrounds half of the Hawaiian islands in this
true-color Terra MODIS image acquired on May 27, 2003. Sunglint reveals
turbulence in the surface waters of the Pacific Ocean. If the surface of
the water was as smooth as a perfect mirror, we would see the circle of
the Sun as a perfect reflection. But because the surface of the water is
ruffled with waves, each wave acts like a mirror and the Sun’s reflection gets
softened into a broader silver swath, called the sunglint region.
In this scene, the winds ruffling the water surface around the Hawaiian
Islands create varying patterns, leaving some areas calmer than others.
Southwest of Hawaii and Maui, on their leeward sides, calmer waters are indicated by brighter
silver coloration. Conversely, notice how most of the vegetation on the Hawaiian Islands grows on their northeastern, or windward, sides.
From lower right to upper left, the “Big Island”
(Hawaii), Maui, Kahoolawe, Lanai, Molokai, Oahu, Kauai, and Niihau
islands all make up the state of Hawaii, which lies more than 2,000 miles from
any other part of the United States. The small red dot on the Big
Island’s southeastern side marks a hot spot on Kilauea Volcano’s
southern flank. Kilauea has been erupting almost continuously since
January 1983, and is one of the world’s best studied volcanoes.
