Project Lake Azuei, Haiti

PRESENTATIONS AT INTERNATIONAL MEETINGS

The 3-week data acquisition phase of Project Lake Azuei was completed at the end of January 2017.  

We are now in the data processing and interpretation phase which will continue through 2020.  As progress is made on this project, reports, presentations, images and publications will be posted here.  For the full Field Report, please go to the "FIELD REPORT" tab.

​

To highlight undergraduate student contributions to this project, we will display their work on a dedicated "STUDENT WORK" page of this site.
