This natural-color Landsat 8 mosaic of the Chesapeake Bay region was made using the band combination 4-3-2 (Red-Green-Blue). The image was then pan-sharpened using band 8 to increase the spatial resolution of the image from 30 meters to 15 meters. The image was acquired in July 2018.

Frozen Chesapeake Bay
The MSS (Multispectral Scanner System) on Landsat 1 captured the image on the left during the exceptionally cold winter of 1976-1977. The mosaic combines two Landsat scenes acquired on February 7 with a third captured on February 8. The landscape is shown in false color (MSS bands 6-5-4). The image on the right was captured by the OLI (Operational Land Imager) instrument on Landsat 8 and 9. It combines four scenes acquired February 4 and February 5, 2026. The landscape is shown in false color (OLI bands 5-4-3). In both images, ice appears in shades of blue, green, and white. On land, snow appears white, vegetation is red, and urban areas take on brown-gray tones.
