Marine Sciences Work of Integral Principal Receives an International Audience
March 11, 2015

With extensive experience in sediment transport and marine renewable energy, Integral Consulting‘s Marine Science and Engineering group has been presenting on new research and technologies, while receiving an international audience. Integral Principal Craig Jones, Ph.D., coauthored an intertidal sediment study that was presented in Brazil, and co-led a session on marine and hydrokinetic (MHK) energy at a U.S. Department of Energy (DOE) workshop in Oregon. He was also invited to present with Integral Managing Scientist Dr. Grace Chang at a January Ocean Wave workshop at the University of New Orleans.

The sediment study, titled “Linkages between Morphological Trends and Sediment Properties in Estuaries,” was presented at the 17th Physics of Estuaries and Coastal Seas conference in Brazil. Coauthored by Bruce E. Jaffe with the U.S. Geological Survey, the study examines how sediment transport is affected by morphology and physical forces, including the influence of waves, tides, and winds. It also explores how sediment properties are affected by deposition and erosion. The study results show the benefits of using site-specific data from SEDflume, a device for determining the erodibility of sediment. These data can inform restoration, environmental, and engineering projects, and assist with effectively restoring habitat and reducing risk.

As part of a series on marine renewable energy, Dr. Jones also co-led a workshop session at the U.S. Department of Energy Marine and Hydro-Kinetic Workshop in Portland, Oregon. The session, titled “Environmental Effects of Marine Energy Development on Physical Systems,” was designed to inform federal and state regulators on the physical impacts of MHK devices on the ocean, including the change of local ocean ecosystems due to the installation of new MHK devices. In January, Dr. Jones, Dr. Chang, and Jesse Roberts of Sandia National Laboratories presented a workshop titled “Wave Energy Converter Effects on Wave, Current, and Sediment Circulation: A Coupled Wave and Hydrodynamic Model of Santa Cruz, Monterey Bay, CA.” They discussed how wave model simulations can provide environmental assessments of wave energy converter arrays, which have the potential to alter nearshore wave propagation and circulation patterns.
