200th Celebration Desktop Wallpaper

For centuries weighted lines were lowered by hand to measure ocean depth, Today, NOAA ships and underwater robots measure depth with hi-tech sonar. NOAA scientists turn this data into maps of the sea bed, like this image of the underwater world at the entrance to Portsmouth Harbor, New Hampshire. The data can be used for many purposes including safe navigation, fisheries research, and flood evacuation plans.
