| 説明 | NORFOLK, Va. -- Dustin Brooke, a survey technician with the Norfolk District, U.S. Army Corps of Engineers, sets up GPS equipment at the district’s headquarters prior to conducting a survey in the Elizabeth River for a new breakwater, March 27, 2012. Surveyors are marking out the future breakwater location, which will protect a new oyster reef constructed by the Corps of Engineers in partnership with Seatack Elementary’s fourth grade. The reef is part of the district's and the children's effort to improve the water of not only the Elizabeth River, but the Chesapeake Bay. (U.S. Army photo/Patrick Bloodgood) |
