We found several typographical errors in picture identification numbers for the impact sites. For researchers that would like to examine all of the relevant, original images, we recommend using the following, corrected "Supporting Online Material" document, instead of the one provided by Science. Prior to publication, we attempted to have Science replace their material with our corrected copy, but, unfortunately, they did not.

This 81-page catalog provides details about the 20 new impact sites identified on Mars as having formed between May 1999 and March 2006, including pictures showing the site before and after the impact and Mars Global Surveyor Mars Orbiter Camera images of each impact feature.

At the time of the Science paper was reviewed, revised, and accepted for publication, some of the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) data used in the study had not yet been archived. MOC data are archived on a rolling basis in six-month increments. Some of the data used in the study were scheduled to be archived with the NASA Planetary Data System (PDS) (Imaging Node) in November 2006 (MOC data from mission subphases S11–S16), the rest in April 2007 (S17–S22). All MOC data acquired prior to October 2005 were previously archived and available from the NASA PDS or through the Malin Space Science Systems MOC Gallery. The Mars Odyssey THEMIS and Mars Express HRSC data used in this research were also previously archived with the NASA PDS.
MGS MOC data due to be archived with NASA PDS in November 2006 and April 2007 that were used in the study of recent martian impact sites and evidence for recent gully activity are presented below in pre-archival (not validated) form. The user should be especially cautious about the quality of information contained in the ".tab" files; these ancillary data were automatically generated and have not been validated. Typically, the labor-intensive data validation process conducted at Malin Space Science Systems will result in improvements and corrections to the image headers and the table (.tab) of ancillary information. For MOC images that have data drops in them, the validation process may also result in improved recovery of the dropped data. Until the images are validated and archived, the data posted on this page are the best available (and were used in this form for our research). Each column header in the table below has a brief explanation (click on the header) of the item listed in that column. De-striped images have not been re-oriented with north up and east to the right.
