The Operational Land Imager on Landsat 9 captured this image of Buccaneer Archipelago on June 11, 2025. The scene encapsulates the striking interactions between land and water in the area where King Sound opens to the Indian Ocean.
The powerful tidal currents stir up sediment in shallow areas, producing the beautiful turquoise swirls visible in this image. This power, however, can be hazardous to seafarers and divers as water rips through the archipelago’s constricted passages. One infamous place of turbulence, known as “Hell’s Gate,” lies in the passage between Gerald Peninsula and Muddle Islands.

As NASA works to make data and research more meaningful and accessible to diverse public and scientific audiences, the agency’s Transform to Open Science (TOPS) program is supporting open science efforts and programs across a variety of scientific disciplines, including climate science and physical oceanography. By leveraging open science principles, NASA encourages and empowers scientists to address critical issues such as melting polar sea ice, rising sea levels, and the overall health of marine ecosystems.
The goal of open science is to make NASA research and data more collaborative, accessible, inclusive, and transparent for everyone from the scientist and student to the city manager and citizen. As part of the Open Source Science Initiative, the TOPS team is committed to providing space for everyone in the scientific community to learn about the variety of open science tools and data available, as well as the importance of open science itself.
Among the communities that have embraced open science is a NASA-funded consortium called Estimating the Circulation and Climate of the Ocean (ECCO). For more than 20 years, ECCO has been producing models of ocean variables such as sea surface height, sea surface temperature, global mean sea level, sea ice concentration, and ocean bottom pressure. For example, tidal currents often exhibit laminar flow characteristics, visible in the upper left and right corners of the image. This scene was collected by NASA’s Landsat 8 satellite on September 24, 2021.
