Where on Earth...? MISR Mystery Image Quiz #6
02/13/2002

Here's another chance to play geographical detective! This Multi-angle Imaging SpectroRadiometer (MISR) image covers an area of about 298 kilometers x 358 kilometers, and was captured by the instrument's vertical-viewing (nadir) camera on December 27, 2001. Use any reference materials you like and answer the following five questions:

1. The large lagoon in the image is named for a particular type of bird. Name the bird.

2. Note the sediment plume emanating from the southern end of the lagoon. Sailors in the 16th century imagined this outlet to be the mouth of a large river. What did they call the river?

3. A series of wave-like points and curls form "cusps" on the inner shores of the lagoon. Which ONE of the following is most responsible for the formation of these cusps?
(A) Violent storm impacts on erosion and accretion
(B) Wind and tide-driven sediment transport and circulation
(C) Tectonic folding associated with nearby mountain ridges
(D) Bathymetric effects of dredging operations

4. True or false: Changes in regional precipitation associated with large scale atmospheric circulation patterns have no effect on the salinity of the lagoon's water.

5. Which one of these is NOT distributed within the area covered by this image?
(A) Ruppia maritima
(B) Chelonia mydas
(C) Tapirus bairdii
(D) Microcystis aeruginosa

MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

A new "Where on Earth...?" mystery will appear periodically. The image also appears on the Earth Observatory, http://earthobservatory.nasa.gov/, and on the Atmospheric Sciences Data Center home pages, http://eosweb.larc.nasa.gov/, though usually with a several-hour delay.
