The project team will conduct three phases of geophysical surveys and educational collaboration in Haiti. The first phase completed in 2012 –Testing around the Léogâne area. These tests included several 1 km gravity transects, two 1 km seismic lines (accelerated weight drop and 72-channel recorder), all accompanied by GPS and total station mapping.
The second phase involves more detailed and deeper penetrating seismic surveys. This phase ended up with over 4km seismic and gravity line, several velocity and density measurements at the laboratory for the collected rock samples and 5 km to 10km long chirp imaging over the lake. All of these activities include personnel from the State University of Haiti and Bureau of Mines and Energy.
The third phase of the project involves an airgun survey with our 24-channel MicroEel streamer in addition to further vibroseis surveys. The array of geophysical equipment will include: a Scintrex CG-5 gravimeter, Geometrics 60-channel Stratavisor seismic recorder, Trimble GPS instrument, and Leica total station surveying unit. We are also planning to coordinate the last phase surveys with Dr. Robert Wiley (UH) for drilling a shallow water well (<600ft) and acquiring some well-log data.
Project team is currently finalizing the arrangements for the next round of surveys and waiting for wet season to pass. Planned surveys are conducting deeper seismic surveys (more receivers, longer lines and more deeply penetrating source) and further lake surveys with chirp, side-scan and boomer systems.
