Tim Hodson

Tim Hodson is a master's student who wants to color the world with his maps. After completing his undergraduate studies at the University of Wisconsin-Madison, Tim joined the Quaternary Department at the Illinois State Geological Survey where he toured Illinois, assisting state geologists with their mapping and research. Since joining NIU's (Ant)Arctic Avengers (led by Dr. Ross Powell), Tim's research has shifted poleward, towards the glaciers of coastal Alaska.

In 2010, Tim joined USGS scientists aboard the Research Vessel Steller during ground-truthing investigations in Glacier Bay National Park and Preserve, Alaska. Using a submersible video sled, the team combed the fjord floor, collecting footage of benthic habitats within the park. The results of this study will help scientists and staff manage the park’s ecosystems and provide a baseline for further research in the region. This baseline will help to determine changes in the fjords’ ecosystem over time. When he is not mapping, Tim contributes his time to the open source movement, helping to test and disseminate free tools for geoscientists.
