Here's another chance to play geographical detective! This Multi-angle Imaging
SpectroRadiometer (MISR) image covers an area measuring approximately 320
kilometers x 260 kilometers, and was captured by the instrument's vertical-viewing
(nadir) camera on October 26, 2001.
NOTE: To make identification of this scene more difficult, the image has been rotated
such that north is not necessarily at the top.
Below are nine statements about the islands highlighted in this image. Use any reference
materials you like, and mark each statement true or false:
1. There are no endemic species of cactus on any of the islands.
2. Flamingos, whose diets include crustaceans, tiny fish, and algae, can be found wading
in brackish lagoons.
3. A change in ocean temperature associated with an episodic disruption in atmospheric
circulation led to a precipitous decline in the local penguin population.
4. Discovery of the islands is generally attributed to a 16th century Spanish missionary
whose vessel veered off its intended course.
5. A recurring and dramatic geological event took place on the westernmost island in
1988, 1991 and 1995, causing injury or death to over 2,000 people.
6. Several plant species are endangered due to decimation by goats and competition with
non-native vegetation.
7. Within the archipelago there are at least half a dozen freshwater lakes with diameters
exceeding 250 meters.
8. A particular endangered animal sub-species is survived by a single male, and attempts
at breeding have so far proved unsuccessful.
9. Chapter 13 of a book written in the mid-nineteenth century by a native of Shrewsbury,
England is primarily concerned with the islands of this archipelago.
E-mail your answers, name (initials are acceptable if you prefer), and your hometown by
Tuesday, December 18, 2001 to suggestions@mail-misr.jpl.nasa.gov.
Answers will be published on the MISR Quiz page in conjunction
with the next weekly image release. The names and home towns of respondents who
answer all questions correctly by the deadline will also be published in the order
responses were received. The first 3 people on this list who are not affiliated with NASA,
JPL, or MISR and who did not win a prize in the last quiz will be sent a print of the
image.
A new "Where on Earth...?" mystery appears as the MISR "image of the week"
approximately once per month. A new image of the week is released every Wednesday at
noon Pacific time on the MISR home page http://www-misr.jpl.nasa.gov. The image also appears on the
Earth Observatory, http://Earthobservatory.nasa.gov/, and on
the Atmospheric Sciences Data Center home page, http://eosweb.larc.nasa.gov/, though usually
with a several-hour delay.
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.
