Shapefiles / Database of Open Basin Lakes on Mars

In Fassett and Head, 2008 we described valley-fed depressions with outlets on Mars that we interpreted as evidence for hydrologically-open lakes on the surface of Mars. An image catalog showing outlines of these possible paleo-lakes was included in the paper (see the supplementary material).

Here we provide some supporting data for that study, as well as a few additional (n~14) possible paleolakes found in the last two years.

Shapefiles of Lake Outlines. These are the outline within which we calculated morphometric parameters. Generally, these correspond to a current closed contour on the MOLA grids. In some cases, however, either holes in MOLA data or later processes (i.e. a deep young crater) led us to interpret to be the approximate outline of the original basin based on the inferred outlet elevation. Most outlines are typically in a Mars equidistant cylindrical projection but calculations of areas and volumes were made in more accurate local projections (sinusoidal with a local central longitude).
