Widespread crater-related pitted materials on Mars: Further evidence for the role of target volatiles during the impact process

“…These show that the pit floors often contain common and readily recognizable aeolian bedforms. This is corroborated by observations of pit walls and floors that are distinct in color, suggestive of differences in composition (Delamere et al, 2010). In rare cases, where the pits are well-exposed and relatively free from surface deposits, outcrops containing meter-to decameter-sized light-toned rounded to angular rock fragments can be observed outcropping in the pit walls (Fig.…”

“…Aeolian bedforms (bluer) are apparent on the floors of pits. The smooth pit walls (lighter-tones) may possess coatings, dust or are potentially comprised of ferrous-bearing phases (Delamere et al, 2010). The semi-isolated pit with the ''spur and gully'' morphology in the upper left inset is $50 m in diameter.…”

Changes in blast zone albedo patterns around new martian impact craters

“…It is a difficult challenge to perform quantitative photometry on HiRISE data (Delamere et al, 2010). We have developed the following technique to measure changing albedos in successive images, which addresses some of these challenges.…”

“…Such relative albedos are more accurate than absolute albedos (Delamere et al, 2010) and to first order are independent of lighting conditions. They minimize apparent changes between images due to differing lighting conditions and atmospheric effects.…”

Interpretation and analysis of planetary structures

“…Okubo et al, 2008;Okubo, in press). The image is a HiRISE color composite (Delamere et al, 2010) from PSP_ 003540_1735 overlain on a 1 m/pixel DEM, with no vertical exaggeration. The lower edge of the image is w750 m wide.…”
