Interesting Areas |
|
|
All areas of the earth can be viewed from
spacecraft circling the globe or from spacecraft in geosyncronous orbits. The
areas which can be photographed provide interesting images.
Some Examples:

NM23-739-093 Tongue of the Ocean, Bahamas
Winter/Spring 1997 " The shallow Bahama shelf and the southern portion of
the deep Tongue of the Ocean (darker water, upper right) can be seen in this
northwest-looking view. The Tongue of the Ocean is one of two main branches
that form the Great Bahama Canyon. The vertical rock walls of this submarine
canyon rise 14060 feet (4285 meters) from the canyon floor to the surrounding
seabed. The Grand Bahama Canyon has been traced for more than 140 miles (225
km) in length. The canyon has a width of 23 miles (37 km) at its deepest point
and an average floor slope of about 300 feet per mile (60 meters per km).
During the last Ice Age, nearly 12000 years ago, much of the Bahama Shelf was
above sea level."

STS075-721-047 Mekong River Delta, Vietnam
February 1996 "Rising on the Plateau of Tibet, the Mekong flows generally
southeast for 2600 miles (4160 kilometers) and empties into the South China Sea
through a large delta. The Mekong River Delta covers 75 000 square miles (194
250 square kilometers), and, with its many channels still depositing sediment,
the delta continues to grow. The vast swampy delta, crisscrossed by many
channels and canals, is one of the greatest rice-growing regions of Asia. Even
though rainfall is heavy during the summer months, winters are dry and require
irrigation for most of the rice-growing area. The Mekong River Delta was the
scene of heavy fighting during the Vietnam War. Barely discernible northwest of
the delta is Ho Chi Minh City, formerly Saigon. Point Cau Mau, the southern tip
of Vietnam, is visible southwest of the delta."

of the preset term, "Deforestation," yielded an image of Mt Kilimanjaro with a
lengthy description.

STS41B-046-2957 "Mount Kilimanjaro, Tanzania February 1984
Mount Kilimanjaro, the highest [19 340 feet (5898 meters)] and most celebrated
mountain in Africa, is the centerpiece in this east-looking, low-oblique
photograph. Looming some 16 000 feet (4900 meters) above the plains that spread
out from its base, the mountain dominates its surroundings. Composed of three
separate volcanoes, massive and complex Kilimanjaro covers an area 60 miles
(100 kilometers) long and 40 miles (65 kilometers) wide. The volcanoes, whose
lava fields overlapped and partially obliterated each other, began erupting
approximately 2 million years ago. At the center is the culminating massif,
Kibo (snow-covered peak near the center of the photograph), flanked by the
lower summits of Mawenzi to the east and Shira to the west. The peaks of Kibo
and Mawenzi are joined by a broad saddle 7 miles (11 kilometers) long. Because
of Kilimanjaros great height, the mountain influences its own weather.
Winds incoming from the Indian Ocean are deflected upward by the slopes and
drop their moisture as rain and snow. This moisture results in a variety of
vegetative zones that contrast dramatically with the savanna grasses and
semidesert scrub on the surrounding plains. The mounts lower slopes,
probably once forested, have been cleared for the cultivation of coffee, corn,
and other crops. At higher elevations [approximately 9800 feet (3000 meters)]
lies a belt of tropical rain forest that gives way to grasslands and moorlands.
This belt, in turn, is replaced by high-altitude desert [near 14 500 feet (4400
meters)]. At the highest elevations is a zone of permanent ice and snow that is
responsible for the name Kilimanjaro, which in Swahili means "the mountain that
glitters." http://earth.jsc.nasa.gov/Images/STS41B/lores/STS41B-46-2957.JPG

Mount Ararat (16,940 feet, 5165 m) is the largest
volcano in Turkey. Although not currently active, its most recent eruption has
probably been within the last 10,000 years. It is located in extreme
northeastern Turkey, near the borders with Iran and Armenia. Southwest of the
main peak lies Little Ararat ( 12,877 feet, 3896 m). Ahora Gorge is a
northeast-trending chasm dropping 6000 feet from the top of the mountain and
was the focus of a major earthquake in 1840. A number of claims by different
explorers to have found remnants of Noahs Ark on Mt. Ararat have led to
continuing expeditions to the mountain, many of which have focused their
searches on the gorge area http://eol.jsc.nasa.gov/debrief/STS102/STS102-344-23.htm

STS61A-200-0046 Ocean Dynamics, Sea of Crete
November 1985 Despite the underexposure of this southeast-looking
photograph of the Sea of Crete and the small amount of information that can be
gleaned from the islands (dark areas silhouetted against the water
background),... This sunglint photograph shows a tremendous amount of dynamic
surface water detailspiral eddies in the Sea of Crete north of the island
of Crete, two very pronounced V-shaped ship wakes in the darker water off the
northeast coast of Crete (indicative of ships traveling at high speeds through
a rather calm sea), and island wakes around the smaller islands north of
Crete.

STS049-077-077 Suloy and Ship Wake, Red Sea May
1992 This spectacular, near-vertical photograph clearly shows a suloy in
the Red Sea between the Dahlak Archipelago and the Farasan Islands. A suloy is
an unusual condition of the sea in which the surface is covered by precipitous
and irregular waves that form lines at a boundary. The boundary in this
photograph is caused by the flow of water in and out of the Red Sea from the
Gulf of Aden through the Strait of Mandeb (Vale of Tears). Little is known
about suloys or "lines of chaotic seas," but knowledge increases because of
photographs obtained from low-Earth orbit. A ship wake, formed from the bow of
a moving ship, is visible as a V-shaped pattern just off center in the dark
blue waters.

STS039-080-048 Volga River Delta, Russia May
1991 The main channel of the Volga River (lower right corner) fans out into
several channels as the river enters the northern edge of the large Volga River
Delta. The lighter-colored, muddy-looking water of the Volga can be seen mixing
with the extensive water of the very low-lying, more stagnant, swampy water of
the delta. The paralleling, east-west aligned features (upper right and left
middle) are alternating sand ridges (light lines) that are separated by
numerous lakes (dark, linear-looking features). There are more than 700 salt
lakes included within the salt marshes of the Volga River Delta. The important
Russian city of Astrakan with a population that exceeds 500000 people is
visible (upper center). Astrakan has developed into a vital urban area in spite
of the fact that it is 72 feet (22 meters) below sea level. The citys
growth has been aided by several important factors including irrigated
agriculture; natural gas production; source of medicinal materials and salts;
an abundance of building products, such as sand and limestone; and water fowl
and fish habitats. A variety of industrial activities, including a large
producing gas field (pattern of intersecting, light-colored lines bottom
center) that is located along the east bank of the Volga River, has also helped
Astrakan become an important city in this semiarid, steppe climate.
