This search engine allows users to search a database of NASA satellite images of all Earth's water habitats including everything from oceans to ice. Users may select water habitats from a list and set search output parameters to show results as thumbnails, graphically intense images or text only. Due to the abundance of images in the database, searches may take a moment.
