Peter Lonsdale's lab came to the ship
from Scripps Institution of Oceanography where they study
marine geology. In Alaska they mapped the sea floor.

Barry came to Scripps Institution of Oceanography via the U.S. Navy and the University of Colorado, Boulder. He served in the Navy as a Sonar Technician - STG1(SW) where he learned oceanography, electronics repair, and anti-submarine warfare. His job at the Navy involved using sonar systems to track submarines. With support from the GI bill, he went on to the University of Colorado, Boulder and received a bachelor's degree in geology.

Barry came to Scripps as a geology graduate student in 1996 and began work towards a doctoral degree. He is currently working on his thesis, which involves using knowledge of the shapes of geologic features to infer how rifting occurs. Scientists that study the shapes of marine features are called marine geomorphologists. Barry expects to finish his thesis and graduate this summer in 2001.

At sea, he has used multibeam sonar mapping tools, towed magnetometers, and shipboard gravimeters to map the sea floor. Topographic maps constructed from sonar measurements reveal features such as faults, volcanoes, and landslides; paleomagnetic anomaly maps constructed from magnetometer readings provide ages of the seafloor; and gravity measurements allow the inference of structures hidden below the seafloor. Using all three types of data, Barry unravels the tectonic history of rifted areas. On the Alaska expedition Barry and other members of the Lonsdale lab, mapped Kodiak Seamount using multibeam sonar. Their map exposed the major fault along which Lisa Levin's group would find cold seep communities. In his spare time Barry and his wife volunteer for the San Diego House Rabbit Society and Audubon Society. He also enjoys bird watching, hiking, camping, and nature photography - anything outdoors.

Christina is a marine geologist. She became interested in geology as an undergraduate at Stanford University, where she earned a B.S. in geology. After graduating from Stanford and spending a summer mapping the Rocky Mountains in Montana, Christina returned to her home state of Texas where she earned an M.S. in Geology at the University of Texas at Austin. The research and field work she did at Texas focused on the marine geology and geophysics of the seafloor south of New Zealand. In 1994, she participated on her first of 11 cruises onboard various research vessels surveying around the Pacific Ocean. To gain some practical experience, Christina spent one summer working for Mobil Exploration and Producing in Houston, and one summer working for Texaco Exploration and Production in New Orleans. Her growing interest in marine geology led her to Scripps Institution of Oceanography in 1996 where she entered the Ph.D. program in earth sciences.

Christina investigates the deformation and structural features associated with subduction zones. Her work has made her a world traveler, taking her to such places as Peru, Chile, Western Samoa, the Marshall Islands, Alaska, and Baja, California. During the Alaska cruise, off Kodiak Island, she worked closely with fellow graduate student Barry Eakins and their advisor Peter Lonsdale mapping the sea floor. Besides working on her thesis, Christina is also interested in the accurate dissemination of scientific information to the public as well as scientific application to policy-making decisions. She is currently part of the mentor program at Mar Vista High School's Poseidon Academy and in May of 2000 raised money and awareness for the Leukemia and Lymphoma Society by running the Rock 'n Roll marathon.
