Summary for Field Activity Number 1979-014-FA

Alternate Leg ID: NE-4-79

Area of Operations: western Lake Ontario, Great Lakes, New York, United States, North America

Dates: June 19, 1979 to July 10, 1979

Objectives: 1. Collect high-resolution and airgun seismic reflection profiles and magnetic profiles over western Lake Ontario to identify geologic hazards that might be related to the low-intensity earthquake activity in western New York. 2. Collect Alpine piston cores to correlate lithology with acoustic stratigraphy and measure paleomagnetic vectors. 3. Collect Van Veen grab samples for specific bottom types.

Type of Activity: Sampling
Seismic profiling

Information to be derived: Seismic profiles

Summary: Collected 18 lines of seismic data. 7 kHz data: 577 km; 2.5 kHz data: 577 km; 1 in. airgun data: 577 km; Sidescan data: 12 km; Magnetometer data: 542 km; Stations: 11; Piston cores: 15; Grab samples: 6.
