Equipment Used: 512 chirp, Differential GPS, Gravity Core, Vibracore, 512 chirp-source, Other, SWATH plus-M , AML SV Plus, AML SV Plus #2
Information to be Derived: bathymetry, subbottom, core samples
Summary of Activity and Data Gathered: 34 boomer and 94 chirp subbottom profiles were collected in Lake Ozette. High resolution bathymetry and 50 cores were collected from Lake Ozette. 93 chirp profiles were collected in Lake Crescent.
Staff: Jackson Currie, Peter Dal Ferro, Daniel Powers
Affiliate Staff:
Notes: 3-weeks of fieldwork on site, plus equipment transit from Santa Cruz. All USGS personnel will be staying in an NPS lodge near the lake. Will possibly collect subbottom profiles in Lake Crescent if there is leftover time.
