This map was modified from one created by the U.S. Fish and Wildlife Service. It shows Sand Island, the largest of the 3 islands in Midway Atoll National Wildlife Refuge. Barb Mayer added the designations for these study areas: marine debris (in blue*), albatross (green; both Laysan and Black-footed Albatross), Red-tailed Tropicbird (red)...
,,,and Laysan Duck wetland study areas, called "seeps" (represented by S). But I forgot that not all of the wetland areas are seeps; some of them are true ponds (like #12, Brackish Pond), or even just low asphalt areas (like #14, called "Tarmac") where water collects during stormy weather. To show wetland areas on the map, instead of an "S," I should have used a "W." The true seeps are S#1, 3, 4, 8, 9, 10 16, 17, 18, 19 and 20. If you want to find out what a "seep" is, read FOAM's "Laysan Duck Trans-location to Midway. "
*There is one marine debris study area on Eastern Island. Neither Eastern nor the smallest Spit Island, have any buildings.
