DescriptionSan Francisco Bay ESA22014515.jpeg |
English: The Copernicus Sentinel-2 mission takes us over San Francisco Bay in the US state of California. Zoom in to view this image at its full 10 m resolution. San Francisco Bay, almost 100 km in length, is a shallow estuary surrounded by the San Francisco Bay Area – an extensive metropolitan region that is dominated by large cities such as San Francisco, Oakland and San Jose. The densely populated urban areas around the bay contrast strongly with the surrounding green forest and park areas. In the upper right of the image, the delta of the Sacramento and San Joaquin rivers is visible – with the brown, sediment-filled water flowing down into San Pablo Bay. Here, the murky waters mix before flowing into the larger bay area, which is connected to the Pacific Ocean via the Golden Gate strait. A large sediment plume can be seen travelling westward into the Pacific in the left of the image. The Golden Gate Bridge, around 2.7 km long, is visible crossing the opening of the bay into the Pacific Ocean between Marin County and the city of San Francisco – which can be seen at the tip of the southern peninsula in the centre of the image. Treasure, Angel and Alcatraz islands can be seen sticking out of the waters of the bay, with several bridges connecting its east and west shores. Several boats are also visible. The bright green and yellow colours in the bottom right of the image are salt ponds and are part of the Don Edwards National Wildlife Refuge. Covering an area of around 120 sq km, the refuge contains salt marsh, mudflat and vernal pool habitats for millions of migratory birds and endangered species. Sentinel-2 is a two-satellite mission to supply the coverage and data delivery needed for Europe’s Copernicus programme. The mission’s frequent revisits over the same area and high spatial resolution allow changes in water bodies to be closely monitored. This image, captured on 25 January 2019, is also featured on the Earth from Space video programme. |
