Summary for Field Activity Number 1980-036-FA

Alternate Leg ID: GUAT 80

Area of Operations: Lago de Atitlan, Laguna de Ayarza, Bahia de Amatique, Guatemala, Belize, Bay of Honduras, Caribbean Sea, Central America, North Atlantic

Dates: January 19, 1980 to Mar 06, 1980

Objectives: 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.

Type of Activity: Sampling
Seismic profiling

Information to be derived: Samples and chemical analysis
Grain size analysis
Sea floor map
Bathymetric maps
Morphology

Summary: 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.

USGS Project Number: CALDERA LAKE
