متن کاملGlacial Flow Modeling of the Martian North Polar Layered Deposits
Introduction: Recent observations of the Martian North Polar Layered Deposits (NPLD) suggest that glacial flow may govern its large-scale evolution [1]. There are two basic glaciological questions of climatological importance: (1) How fast is the NPLD presently flowing? (2) And does the NPLD experience " ice ages " : i.e., episodes of glacial advance and retreat at other orbital epochs? To addr...
متن کاملDecameter thick remnant glacial ice deposits on Mars
OnMars, a smooth, draping unit—the “latitude-dependant mantle” (LDM), believed to comprise meter thick layers of dust and ice—extends from the midlatitudes to the poles, covering at least 23% of the surface. We show that the LDM can be 30m deep on pole-facing crater walls, and by measuring the erosional and depositional volumes of small gullies that incise these LDM deposits, we show that it mu...
متن کاملPavonis Mons Fan-shaped Deposits - a Cold-based Glacial Model
Introduction: Each of the three Tharsis Montes volcanoes on Mars has unusual fan-shaped deposits located exclusively to the northwest of each shield. The fan-shaped deposits of the Tharsis Montes generally share three major facies: 1) Ridged facies, 2) Knobby facies, and 3) Smooth facies. Here we examine the Pavonis fan-shaped deposits using new Mars Global Surveyor and Mars Odyssey data. Any e...
متن کاملExtensive Deposits on the Pacific Plate from Late Pleistocene North American Glacial Lake Outbursts
One of the major unresolved issues of the Late Pleistocene catastrophic-flood events in the northwestern United States (e.g., from glacial Lake Missoula) has been what happened when the flood discharge reached the ocean. This study compiles available 3.5-kHz high-resolution and airgun seismic reflection data, long-range sidescan sonar images, and sediment core data to define the distribution of...
