Antarctic Circumpolar: Large plankton bloom about 8 degrees east southeast of Tasmania associated with the Antarctic Circumpolar Current in the subantarctic front zone. 100 mm (Nadir: 45.1S 154.5E).

The Volga River and Volgograd under snow: Contrast in brightness shows up many features in this near-vertical view of the great bend of the Volga River -- dark, open strip of water, center. The Volga flows south into the view from top right, then southeast from the center to the bottom. Volgograd appears as the grey zone along the left (west) side of the open water. Presumably the icefree part of the river opposite Volgograd relates to the slightly warmer water which is spilled from prominent, ice-covered Lake Volgograd (top right). The wide patterns of swirls, center to lower right, are numerous meander bends on the Volga's floodplain (up to 20 miles wide), highlighted by snow. The main course of the Volga is once again ice covered in this floodplain belt. The Volga-Don Canal can be seen leaving the river just south of the bend, exiting the view center left. This canal, with others in the Moscow region, allows barge traffic to move through the Russian heartland, from the Black Sea to the Baltic at Leningrad. The long parallel lines in threes and fours are l ines of trees used as wind breaks. They stretch across Russia for hundreds of miles.

Colorado, New Mexico: Rare, clear, snow-dusted views southward down the northern Rio Grande rift of southern Colorado and northern New Mexico. The San Luis valley is in the mid-ground, with the shield volcano of Mt. San Antonio centered in the valley. In the structural embayment in the Sangre de Cristo range Taos and from there, the long southwest-trending Embudo transfer fault zone can be seen cutting across the rift valley. Valle Grande caldera of the Jemez Mts. and the rift fault bounding the Nacimiento range are also sharply defined.

Sinai Peninsula: Excellent photo of the fault-bounded block that extends from Gebel Ikma to Gebel Abu Huswa, along the western margin of the Sinai Peninsula. North-northwesterly faults related to Gulf of Suez/Red Sea rifting are dominant but faults of other orientations are also well defined. This frame is one of a fine series (Frames 28-33) of detailed views along the eastern margin of the Red Sea rift; several pairs are well spaced for stereo viewing.
