Water Surface Turbulance and Internal Waves, Norfolk, VA, USA

STS040-614-047 (5-14 June 1991) --- This image is of the Norfolk, Virginia -- Southern Delmarva Peninsula Southern Chesapeake Bay Area as seen in sunlight. The exposure is adjusted to emphasize the water patterns present. The outgoing tide generates considerable turbulence as it passes through the mouth of the bay. This is displayed by differences in reflective properties of the water surface due to differences in slope and turbidity. Ship wakes and the wakes of subsurface structures are seen clearly. The bridge tunnel system linking Norfolk with the peninsula and its effect on the system is quite apparent. Sunglint images over land areas were also acquired which emphasize land-water boundaries as demonstrated here in the small Delmarva inlets as a tool for wetland mapping, and river, lake and even pond description. During the first few days of the STS-40 mission the Eastern Seaboard of the United States was free of clouds and haze providing excellent photography of many of the major cities and the countryside of that area as well as the Gulf Stream.
