Jupiter's moon Europa is home to one of the youngest, and most complex surfaces in the solar system. The Voyager and Galileo spacecraft imaged numerous ridges, bands, and chaos st ructures. However, those missions were only capable of imaging~15% of the moon at resolutions better than ~500 m/pixel. To better characterize the global-scale processes operating on this moon and formulate geophysical models, a comprehensive and consistent global geologic map that contains both global and regional units and their stratigraphy is necessary. Building on our recent USGS global geologic map, the goal of this project is to provide an order of magnitude (100s of m/pixel relative to km's /pixel) understanding of the defined global units. This work will map the type and distribution of geologic structures that have formed on the surface that we see today, allow for extrapolation of units across the globe, improve characterization of key stratigraphic markers, and identify the first set of consistent moderate resolution units.
We are seeking a postdoctoral researcher to generate regional-scale image mosaics that can be placed in context of the existing USGS Europa global image mosaic, perform geologic mapping of these mosaics, assess the relative stratigraphy of the global and regional terrains. This information will be synthesized to formulate and evaluate models of the formation of evolution of the major Europa land forming units and their relation to the ice shell and subsurface ocean. Dr. David Senske and Dr. Robert Pappalardo (co-advisor) will serve as the postdoctoral advisors. The appointee will carry out research in collaboration with the JPL advisors, resulting in publications in the open literat ure. The position is available immediately .
Candidates should have a recent PhD in Planetary Sciences. The ideal candidate would have expertise in image processing and data manipulation, geologic mapping, and an understanding of geologic processes of icy satellites in general and Europa in particular. Candidates should have very good to excellent abilities in GIS. It is desired that the candidate possess skills in either theoretical or laboratory analog modeling of geological processes. Excellent communication and writing skills are highly desirable. Candidates who have received their PhD within the past five years since the date of their application are eligible. Postdoctoral Scholar positions are awarded for a minimum of one-year period and may be renewed up to a maximum duration of three years.
Candidates should submit the following to this site: CV, representative publications, contact information for three references, and a cover letter stating their research accomplishments and interests.
