Atlas of Mars, Arcadia quadrangle, MC-3
United States Geological Survey
1973, Open-File Report 73-327
This mosaic is made with computer enhanced Mariner 9 pictures, rectified and scaled to a Lambert conformal projection. Computer processing was performed by the Image Processing Laboratory (IPL) of the Jet Propulsion Laboratory (JPL). Processing included contrast enhancement and high-pass filtering which accentuates topographic features while subduing albedo variations. Photographic...
Probable rift origin of the Canada basin, Arctic Ocean
Irvin L. Tailleur
1973, Open-File Report 73-274
Formation of the Canada basin by post-Triassic rifting seems the most workable and logical hypothesis with information available. Speculated counterclockwise rotation of the Alaska-Chukchi continental edge best rationalizes the complex geology of northern Alaska, whereas a single continental block before the Jurassic makes the best palinspastic fit for Arctic America....
Atlas of Mars, Memnonia quadrangle, MC-16
United States Geological Survey
1973, Open-File Report 73-332
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
Atlas of Mars, Lunae Palus quadrangle, MC-10

1973, Open-File Report 73-329
This mosaic was made with Mariner 9 pictures provided by the Jet Propulsion Laboratory (JPL), California Institute of Technology. The Image Processing Laboratory (IPL) of JPL processed the digital pictures to remove image artifacts and geometric distortions, to enhance high-frequency topographic detail while subduing low-frequency albedo variation, and to transform...
