Summary Information for Field Activity 1991-039-FA

Area of Operations: east Flank Kilauea, Alika Debris Avalanche, south Kona slump, west coast Hawaii, Hawaii, United States, North America, North Pacific

Dates: November 15, 1991 to November 27, 1991

Chief scientist: Bill Schwab

   Homa Lee, Michael Torresan - Menlo Park

Objectives: Investigate mass wasting processes on 2 scales: 1) volcanoclastic flows and lava delta failures related to the present Kupaianaha and 1969-1974 Mauna Ulu eruptions; and 2) the giant Alika Debris Avalanche and South Kona Slump off the west coast. Expect 7 days off Kilauea, 3 days off the west coast and 2 day transit. If sea or bottom conditions off Kilauea prevent us from operating effectively, we will devote more time to the west coast. We will obtain 3 dredge hauls on Puna Ridge. All core samples will be assessed for density, sound velocity and magnetic susceptibility using the Schultheiss Multi-Sensor Whole Core Logger prior to splitting. Box core samples will be subsampled and slabbed. Gravity and piston cores will be split, described and tested for vane shear strength and water content. Mass physical properties will be used to calculate downcore variations in acoustic impedance to use in interpreting acoustic backscatter variations on the GLORIA and MR1 mosaics. We will run high-resolution acoustic profiles off Kilauea in a 6 mile grid from Kaimu to Mamoamoa along with bottom camera runs to define coring stations.

Type of Activity: Sampling; Seismic profiling; Photography;

Information to be derived: Sea floor map;

Summary: Cores, dredges, photos, video transects, gravity, magnetics, and bathymetry (3.5 kHz, 10 kHz) data.
