Plankton Bloom, Argentina: A large, multi-colored plankton
bloom was observed and photographed by the STS-88 crew in the South
Atlantic Ocean, off the southern coast of Argentina. The bloom could
mark productive waters that support regional fisheries. Such blooms
are difficult to observe and map from the surface; the view from
space provides the larger coverage necessary for regional
observations.

Whitings, Bahamas: The bright, ellipitical white features in
this photo are whitings in the Little Bahama Bank. Whitings are
suspensions of sediment that are produced by blooms of microscopic
algae. They can produce great quantities of lime muds in places like
the Bahamas. Intricate patterns of sand ridges and channels that are
formed by tidal currents ring the bank, marking the edge between the
shallow bank waters (depths less than 10 m) and the much deeper
offshore waters (dark blue).

Rio De La Plata/Buenos Aires: This photo includes the
burgeoning Argentine capital of Buenos Aires (center), the upper end
of the turbid estuary, Rio de la Plata, and most of the complex delta
at the confluence of the Paraná and Uruguay rivers. The city of 13
million quickly gives way to intense agriculture to the southeast
through west.

Rio De La Plata/Buenos Aires: The Argentine capital of Buenos
Aires, known as the Paris of the southern hemisphere, is the gray
area upper center, with the satellite university city of La Plata to
its upper left.

Rio Limay, Patagonia, Argentina: The Rio Limay, now dammed at
a series of points, flows off the southern Andes Mts., through the
arid lands of Patagonia to the Atlantic Ocean. The browns of the
Patagonian Desert (most of the view) contrast with the greens of the
forested slopes of the Andes (top left). The highest parts of the
Andes appear as light-colored treeless ridges. Lake Nahuel Huapi is
the dark feature along the left side of the view.

Lake Nahuel Huapi, Southern Andes Mountains, Argentina: The
top half of the view shows the ridge crests and valleys of the
southern Andes Mountains. This part of the view appears dark due to
shadow in the valleys. The summits appear as angular, light-colored
treeless ridges, with a patch of white snow top left. Curved Lake
Nahuel Huapi is the dark finger top center. This lake depression was
eroded by glacier ice moving east (from the mountains at the top of
the view towards the Patagonian plains bottom) during the
geologically recent ice ages when the Andes were covered with snow
and ice caps far larger than those of today. The small gray city on
the left (south) side edge of the lake (left center) is the
well-known resort of San Carlos de Bariloche. The Rio Limay appears
bottom right, and flows off the southern Andes Mts., through the arid
lands of Patagonia to the Atlantic Ocean.

Lake Cerros Colorados, Neuquen Prov., Patagonia, Argentina:
Most of the views show the arid landscapes of windswept Patagonia.
The only places where agriculture can be practiced are the valley
bottoms where irrigation water is available. The green swaths
crossing the view are fields in the floodplains of the Neuquen River
(top to bottom) and the Limay River (lower right-should be lower
left). The prominent lakes are Lake Pellegrini, a natural depression
(bottom) probably hollowed out by the persistent and strong winds for
which Patagonia is so well known; and Lake Cerro Colorado, a manmade
lake (top).

Santiago de Chile, Chile: Chile’s capital city stands in
excellent detail in the middle of this view. An airport appears on
the northwest margin of the built-up area and numerous small farms
appear as green rectangles around the city on the left (west) side of
the view. The right side of the view is dominated by the steep slopes
and peaks of the Andes Mountains. Snow can be seen on highest peaks
all down the right (east) side of the view although the photo was
taken in the summer of the southern hemisphere. Santiago routinely
appears partly obscured under industrial haze on Shuttle photographs.
Haze accumulates partly because the city lies in a basin at the foot
of the Andes Mountains (protected from wind), and partly because the
city has grown to a huge size (more than 5.3 million-1991
statistics).

STS088-701-62
|
West Falkland, Falkland Islands: The Falkland Islands are made
up of two major islands, West and East Falkland. Much of the former
is shown here with the dividing waterway between them, Falkland
Sound, appearing along the bottom of the view. Small islands and
capes of East Falkland appear along the bottom margin of the view.

STS088-706-46
|
Songhua River Valley, Northeast China: This early December
(1998) view of the Songhua River shows snow in the floodplain of the
river, with its numerous meandering scroll-bar features, and
numerous, angular farms on the flat country to the north of the river
(top). The smaller Tongken River enters the picture top right and
joins the Songhua on the right margin (center). The major industrial
and coal mining city of Harbin lies just outside the view center
right. It is not clear why small rectangular communities in the
farmland are consistently snow-free, although the existence of trees
in these small centers may explain why the snow is less apparent. It
appears that the snow-free lower part of the view lay immediately
beyond the track of the snow storm which affected the rest of the
scene.
