Other ID: GUAT 80
Organization(s): USGS, Woods Hole Coastal and Marine Science Center
Principal Investigator(s): Charles Paull
Data Type(s): Electro-Magnetic: Magnetics, Location-Elevation: Navigation, Seismics: Air Gun / Water Gun, Seismics: Sub Bottom Profiler
Scientific Purpose/Goals: Conduct geophysical and sampling surveys of two volcanic calderas (Lago de Atitlan and Laguna de Ayarza) and a geophysical survey of a coastal bay underlain by major faults (Bahia de Amatique) in conjunction with Dartmouth College's ongoing volcanology research in the area.
Start Port/Location: Lake Atitlan, Guatemala
End Port/Location: Bay of Amatique, Guatemala
Start Date: 1980-01-19
End Date: 1980-03-06
Equipment Used: 3.5 kHz, Corer - slow, Air gun, Seismic refraction, Single channel hydrophone, Corer - gravity, Motorola Mini-Ranger III, Compass, Marine magnetometer
Information to be Derived: Samples and chemical analysis; Grain size analysis; Sea floor map; Bathymetric maps; Morphology;
Summary of Activity and Data Gathered: The USGS-Dartmouth cooperative group operated in Guatemala from early January to early March 1980. Geophysical and sampling surveys were carried out in two volcanic calderas and a geophysical survey was made in a coastal bay that is underlain by major faults. These operations successfully collected large amounts of seismic reflection and refraction profiles, magnetic intensity data, cores and heat flow information. Vessel TRANSNAVE replaced XAMAN EK on February 28, 1980. Cores: Atitlan=12, Ayarza=5; 3.5 kHz; Airgun; Magnetics; Sonobuoys.
