David Caress is a marine geophysicist by training and a software engineer by slow evolution. His research has involved the use of seafloor mapping, magnetic, seismic refraction and seismic reflection data to investigate topics such as the tectonic evolution of seafloor spreading centers, the deep crustal structure of oceanic islands, the morphology of submarine canyon systems, and the morphology and volcanology of submarine volcanos. Since 1993, he has been the principle author of MB-System, an open source software package for the processing and display of seafloor mapping sonar data. During his fourteen years at MBARI, Dr. Caress has proposed and co-led the development of an autonomous underwater vehicle (AUV) for high-resolution seafloor mapping, continues to oversee mission planning and data processing. During the present expedition he is assisting with survey planning, sonar operation, and leading the data processing effort. Link to personal web page.
