Request permission to collect SeaBeam 2000 multibeam bathymetric data and magnetic amplitude variations from towed magnetometer, while transiting within territorial waters of Peru/Tahiti. The collected data will be incorporated into a global archive of seafloor bathymetry to promote fuller understanding of seafloor morphology and its relation to geological processes. The main survey area will be in international waters, at 8 S, 103 W, and will involve the use of the hull-mounted SeaBeam sonar system and towed magnetometer to investigate the geologic structure of rifted margins near the East Pacific Rise spreading axis. The bathymetric and magnetic data collected within the survey area, and the resulting interpreted geologic structure, will be a significant portion of my doctoral thesis work on how oceanic lithosphere rifts when undergoing extension.
