Biography

Greg spent 4 1/2 years on the research staff at the Scripps Institution of Oceanography, 1 1/2 years as research geologist at Cities Service Research Lab, and 5 years as an associate professor at the University of Tulsa before joining the U.H. faculty in 1989. While at U.H. he has participated in several oceanographic expeditions, including four cruises for the Ocean Drilling Program (one as co-chief scientist). He is a fellow of the Geological Society of America, and a member of the American Geophysical Union, the Society of Exploration Geophysicists, and the American Association of Petroleum Geologists.

During 2006-2008, Greg worked at JAMSTEC in Yokohama, Japan as Advisor to Asahiko Taira, Director General of the Center for Deep Earth Exploration (CDEX). In November, 2007, we completed the first expedition of IODP drilling with D/V Chikyu in the NanTroSEIZE area south of Honshu, Japan. Stage 2 of NanTroSEIZE took place during June-October, 2009, and Stage 3 began in 2010 and continued in 2013 -- Greg was one of four co-chief scientists on Expedition 338.

Current Research

Greg's main research interest is in the highly deformed belts of rock that develop along convergent plate margins. This is, in large part, a study of the processes responsible for mountain building and for the generation of continental crust. Because most convergent plate margins are expressed as trench-arc systems in which the zones of active deformation are beneath very deep water, we must rely largely on marine geological and geophysical remote sensing techniques. These have included seismic reflection profiling, high-resolution multibeam bathymetric mapping, and ocean drilling. He is also interested in giant landslides off the Hawaiian Islands.

Nankai Trough 3D seismic and IODP Drilling project
During April-May, 2006, we conducted a 3D seismic reflection cruise to the new IODP drilling transect in the Nankai Trough. The data set was collected by PGS using the Nordic Explorer with 4 x 4500m streamers. A full 3D pre-stack depth migration (PSDM) was completed by IFREE/JAMSTEC in November, 2007.,br> Since late 2007, the Kumano Transect has been the site of a drilling campaign by IODP using the Japanese drill ship Chikyu. An initial results paper appeared in Science in November, 2007. A second paper that defines the regional tectonic setting of the NanTro transect was published in the IODP Expedition 314/5/6 Initial Report Volume can be found here.

Japan Trench Seismic Reflection Study

After the 2011 Tohoku earthquake, we were funded to join a cruise by our JAMSTEC colleagues to image the epicentral zone. Ph.D. student Brian Boston has been anlyzing the results of these surveys:

Study of Regional Tectonics and Mud Volcanoes along the west coast of Myanmar, NE Indian Ocean

In 2013 Greg began a study of the geology of western Myanmar, including Ramree and Cheduba Islands that were know to have large mud volcanoes. We conducted field studies in the region in May 2013, March 2014, and March 2015 and discovered serpentinites overlain by red cherts that are in turn overlain by deformed Eocene and Oligocene "Indo-Burman Flysch" and Miocene strata. The islands have several large mud volcanoes that we sampled for geochemical analyses by Achim Kopf's group at MARUM, Bremen University.

Study of mud volcanoes along the seaward margin of Kumano Basin, Nankai Trough
In June, 2015, Greg joined a cruise on JAMSTEC's R/V Yokosuka that used the AUV Urashima to collect near-bottom multibeam bathymetry, side-scan and sub-bottom profiles across mud volcanoes that reach the seafloor along the seaward edge of Kumano Basin. Analysis of the data sets is being conducted with Chief Scientist Miho Asada of JAMSTEC and Dr. Kiichiro Kawamura of Yamaguchi University.

Teaching

During Spring, 2014, Greg taught Geologic Hazards (GG130). He taught a graduate course in Well Logging and co-taught Marine Geology (GG 423) with Craig Glenn in Fall, 2014.

During July, 2015 - June, 2016 Greg is on sabbatical leave

Service

Greg was Associate Editor of the Journal of Geophysical Research from 2005-2011.
Most of Greg's other professional service has been with the Ocean Drilling Program: He is a member of the NanTroSEIZE Project Management (now Coordination) Team and was a member of the Western Pacific Panel (1985-1989), the Site Survey Panel (1990-1992) and the Tectonics Panel (1992-1995), and the Planning Committee (PCOM) (1995-1996) and SciCOM (1996-1998).
Greg also co-convened a 3-day workshop on 3D Seismic Imaging at Lamont-Doherty Earth Observatory (8-10 September 2005). See articles in EOS and Scientific Drilling for details.

    Outside Activities

    Greg's major non-professional interest is Hawaiian canoe racing. He is currently paddling with Hui Nalu Canoe Club. In the 2015 season, Greg is mostly filling in during practice but not racing due to his heavy travel schedule.


    The Hui Nalu Sr. Master crew (right) caught a great wave to win by 0.15 sec in the 2004 McFarlane Regatta at Waikiki.
    Note the crew in the background that was swamped by the same wave a minute earlier (photo by T. Ike).
