An important step in seismic interpretation is segmentation of a seismic image into structural and stratigraphic geologic units. Today, we often perform this segmentation using a simple process. We first automatically track seismic events to locate horizons and faults that correspond to the boundaries of geologic units. We then glue those boundaries together to obtain a geologic model. This pro...
We describe an application of machine learning to the problem of geomorphic mapping of planetary surfaces. Mapping landforms on planetary surfaces is an important task and the first step to deepen our understanding of many geologic processes. Until now such maps have been manually drawn by a domain expert. We describe a framework to automate the mapping process by means of segmentation and clas...

Because current energy sources sometimes produce variable power supplies, it ...
Geologic processes strongly influence water and sediment quality in aquatic ecosystems but rarely are geologic principles incorporated into routine biomonitoring studies. We test if elevated concentrations of metals in water and sediment are restricted to streams downstream of mines or areas that may discharge mine wastes. We surveyed 198 catchments classified as "historically mined" or "unmine...
