| 説明 | Osprey Lake (Osprey Pond) (looking ~SW), northeastern San Salvador Island, eastern Bahamas.San Salvador Island has numerous inland bodies of water (see map - newton.newhaven.edu/sansalvador/ssmap_11x17.PDF). Christopher Columbus remarked upon them during his visit in October 1492. These ponds and lakes can have freshwater, brackish water, hyposaline water, normal marine-salinity water, or hypersaline water. Many of these lakes have aquatic biotas quite distinctive from adjacent lakes.Osprey Lake is a medium-sized lake (~420 meters long & ~270 meters wide) that is separated from Northeast Arm Lake (= part of San Salvador Island’s Great Lake System) by a narrow barrier beach composed of loose mollusc shells (= the light-colored horizontal band in the distant center). Osprey Lake water salinites range from near-normal marine to hypersaline. Water enters and exits via a lake drain/conduit and a tidal channel in the barrier beach.Osprey Lake is classified as a construction lake in a pre-highstand depression (see Park et al., 2014) - it formed in response to a sea level rise.-----------------------Reference cited:Park, L.E., A.
