Oceans '13 Conference

OCEANS 2013 MTS/IEEE San DiegoSeptember 23-27, 2013

Our New Theme for 2013: —An Ocean in Common.

The OCEANS ’13 MTS/IEEE San Diego committee invites you to beautiful San Diego to participate in the world’s most diverse and prestigious conference and exposition regarding our most critical resource—the oceans. This will be the 7th time the OCEANS conference has come to San Diego. The team that orchestrated the OCEANS ’03 San Diego conference—the largest OCEANS conference to date—has returned to raise the bar even higher. The ’03 conference, which was a cornerstone of the Scripps Institution of Oceanography’s Centennial, had a total event attendance of 5,400, the exhibition included 301 booths and the technical program exceeded 800 excellent presentations. That international audience, from 46 countries, helped us establish the theme for the OCEANS ’13 conference—An Ocean in Common.

Our Chair

Mark Rognstad


Mark Rognstad is the current chair of the Ocean Engineering Chapter here in Hawaii.
He is a Specialist, HMRG Design Engineer on the faculty of UH-Manoa in the HIGP School of Ocean and Earth Science and Technology.

S. B., Massachusetts Institute of Technology, 1975

Research Interests:
Sonar design and development, Seafloor mapping, Acoustic and optical remote sensing, Digital signal processing

        I'm working on the next generation of the HAWAII MR1 swath bathymetry/sidescan system, which will feature improved transducer arrays, greater dynamic range electronics, arbitrary transmit waveforms, and beam steering/shaping. Another project is the CEROS synthetic aperture sonar system, that adds the capability of detecting and imaging objects buried beneath the seafloor to the usual bathymetry and backscatter data. This system presently acquires 32 bit data from 32 channels at a 48 kHz rate per channel, for just over 6 Mbytes/sec. We plan to double that data rate in the future, and add the capability of higher frequency operation to the system. I've been involved in the SCAMP submarine-mounted swath bathymetry/sidescan system, and hope to upgrade its performance by utilizing all four transducer rows on each side. I'll also be involved in the acceptance testing and field trials of the multibeam sonar system to be delivered on board the University's new AGOR 26 research vessel.

S. Choi

Topic: Underwater Robotics

Dr. Choi will speak on the topic of underwater robotics.

Biography: Dr. Song K. Choi received his BS, MS, & PhD in Mechanical Engineering from Worcester Polytechnic Institute, Carnegie Mellon University, and University of Hawaii at Manoa, respectively. His specialization is in robotics with an emphasis in unmanned systems, automatic control systems, autonomous vehicle design, novel sensor systems, alternative/renewable power sources, and graphic monitoring systems for unmanned vehicles with emphasis on underwater technologies. He returned to Hawaii in 1991 and has been a professor in the Autonomous Systems Engineering, Department of Mechanical Engineering, and has published multiple papers in his arenas of expertise. He has been the assistant dean for the College of Engineering since 2004 and has been working with various primary, middle, and high schools in the State in promoting STEM education through robotics. He is a co-founder and president of Marine Autonomous Systems Engineering, Inc., a Hawaii-based spin-off company specializing in autonomous marine technologies. He is an active member of several engineering and philanthropic societies and serves as a board member on several technology and education organizations.
