Database of Candidate Closed-Basin Lakes on Mars

In Goudge et al. (2015) we describe a catalog of 205 candidate closed-basin lakes contained within impact craters on Mars using a variety of orbital remote sensing data. These basins have an inlet valley that incises the crater rim and flows into the basin but no visible outlet valley, thus making them candidate closed-basin lakes; the presence of a valley flowing into a basin does not necessitate the formation of a standing body of water. Here we provide the catalog of candidate impact crater-hosted closed-basin lakes on Mars presented in this paper.

 

Point Shapefile: This ZIP file contains a point shapefile with the catalog of 205 impact crater-hosted candidate closed-basin lakes identified by Goudge et al. (2015). The shapefile contains the locations of the basins, plus all of the information shown in Table 1 of Goudge et al. (2015). This includes: the basin number [assigned in Goudge et al. (2015)]; location (lat./lon.) of each basin; the inlet type, short [e.g., Figure 1 of Goudge et al. (2015)] or long [e.g., Figure 2 of Goudge et al. (2015)]; the degree of confidence in identification as a closed-basin lake; whether or not a fan is present at the inlet valley mouth; the degradation class of the fan deposit(s) (Class 1 = least degraded, Class 3 = most degraded); the maximum elevation (above the Mars datum) to which the basin could have filled before breaching; the maximum lake area; the maximum lake volume; the host crater diameter (not collected for basins defined by multiple or elliptical craters); the mean depth of the maximum lake extent, which is the maximum volume divided by the maximum area; and references for original basin identifications. Please see Goudge et al. (2015) for a further description of how these data were collected. This file is ready to use with ArcMap and other GIS software. These data are in the Mars_2000 Geographic Coordinate System.

 

Excel File: This Excel spreadsheet contains all of the information in the above shapefile and in Table 1 of Goudge et al. (2015) for non-GIS users. Please see Goudge et al. (2015) for a further description of how these data were collected.
