The THEMIS image mosaic above was used with individual images in ArcGIS to delineate unit contacts and to describe the appearance of each unit and the interpreted process that influenced it.

Each student mapped a 5° by 3° area, and the two maps (left) overlap by 1° in longitude.

The Use of Ground Penetrating Radar (GPR) as a Geophysical Mapping Tool On Glacial Deposits(Jason Bartoszek)

Geomorphic Mapping in MTM -15017, Margaritifer Terra, Mars (Eric Betzold and Annabelle Wardzala)

- This project involved collecting GPR data over several types of glacial deposits (drumlins, eskers, and kames) in order to determine the extent to which GPR can return useful subsurface information.

- GPR signals penetrated ~5m to reveal layering related to the formation of these glacial deposits.

1a. Drumlin in Pendleton, NY: GPR data (left) collected from the top of the drumlin to the west with the 200 MHz antenna (right). Data have been corrected for topography.

1b. Drumlin in Pendleton, NY: GPR data collected near the top of the drumlin from north to south in the area shown in the picture at right. Data have been corrected for topography.

2. Esker in Mendon Ponds Park, Monroe County, NY: GPR data shown here were collected from the top of the drumlin to the side along the line shown in the picture at right. Data have been corrected for topography.

3. Kame in Mendon Ponds Park, Monroe County, NY: GPR data shown here were collected over the kame in the foreground of the picture at right. Data have been corrected for topography.

- Margaritifer Terra, Mars, has experienced a complex history of geomorphic processes.- This project used recent images from satellites in orbit around Mars to analyze the contributions of these

various processes in shaping the surface in quadrangle -15017 on Mars.- Geomorphic maps were produced in ArcGIS based on the image analysis.
