Piston and gravity coring with a coring system provided by UNLV. Cores were primarily collected in Las Vegas Bay to describe sediment thickness and sediment types.
Location
Lake Mead, Arizona, Nevada, United States, North America,
Summary
Cores were attempted at 17 stations using a variety of coring techniques. Cores were collected at 14 stations. Some cores were collected by divers, and 3 different gravity corers were tested as well. Most cores were collected in less than 30 m water where seismic profiles showed sediments mostly to be 0.5-2 m thick. Most of these cores were 30-70 cm long. Core recovery was poor because the fine-grained unconsolidated sediment washed out of the corer as it was being brought back to the surface. Two cores were collected in the deep part of the lake (>130 m), and these cores successfully recovered 160 and 200 cm long cores.
Comments
Original Center People field contained: Ken Parolski - mobilization and electronics technician; Rick Rendigs - coring and sampling technician; VeeAnn Cross - set up the navigation system during the cruise mobilization.
