Whirlpools and other complex currents routinely roil Japan’s Seto Inland Sea. Strong tidal currents send water churning through a maze of channels and narrow straits surrounding thousands of islands in the shallow sea. The islands of the Geiyo archipelago are among them. On May 30, 2021, the Operational Land Imager (OLI) on Landsat 8 captured this natural-color image of currents swirling around several of the Geiyo islands. The complex topography creates areas of choppy and smoother waters depending on the day’s weather and water flows. In this image, some water surfaces gleam with sunglint, an optical phenomenon that occurs when sunlight reflects off the surface of water at the same angle that a satellite sensor views it. One of the most densely populated islands of the group is Innoshima, a mountainous island home to ports, aquaculture, and a rich maritime history. In the 14th and 15th centuries, a clan of “police pirates” known as the Murakami Kaizoku used Innoshima and other nearby islands as their base of operations.
