Abstract:

We know other planets better than our own oceans, yet, the oceans are central to our survival. This presentation starts with a brief introduction to some remarkable phenomena encountered offshore (hydrothermal circulation, salt glaciers, stratified brine pools, seeps, the transition from gas-driven fractures to bubbles and pockmarks, polygonal faults, pipes, chimneys, and submarine volcanoes). Then, we will focus on sediment formation, properties (self-compaction, permeability, stiffness) and implications (geoacoustic properties, bioactivity, gas migration and hydrate accumulation). Characterization and monitoring present unique challenges to both researchers and engineers; we will review recent developments in site characterization (from geophysics to multiphysics probes), sampling and lab testing (from pressure cores to lab-on-a-bench), and in process monitoring (distributed seafloor observatories). Finally, we will address salient engineering issues related to offshore developments (e.g., deep sea mining, foundations, and drilling). 

Biography:

Dr. Santamarina’s research focuses on the fundamental study of geomaterials and subsurface coupled processes. The implementation of this research has involved the development and utilization of multi-scale experimental methods, high-resolution process monitoring, and numerical solutions. Dr. Santamarina has co-authored two books and more than 300 articles which summarize salient concepts and research results. He is a corresponding member of the Argentinean National Academy of Sciences and the National Academy of Engineering. He holds a Ph.D. from Purdue University, M.S. from the University of Maryland, and B.Sc. from Universidad de Cordoba.
