Condensation Trails Over Nova Scotia and New Brunswick, Canada46.0N 65W
The air above the Canadian provinces of Nova Scotia (right) and New Brunswick (left) is criss-crossed by airplane condensation trails (or contrails). These linear streaks form when water molecules gather around the exhaust released into the air by airplanes.
Also of note, although partially obscured by the contrails, are the rusty red sediments in Cobequid Bay (right) and Cognecto Bay (left), two inlets of the Bay of Fundy. As the sediments disperse into the bay, the water fades from red to green to blue.
