Field Activity 2019-622-FA

Identifier 2019-622-FA
Also known as Lake Ozette 2019
Purpose Geophysical mapping and geological sampling of Lake Ozette to investigate earthquake triggered mass transport deposits (Cascadia recurrence project)
Location Lake Ozette, WA
Summary 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.
Info derived bathymetry, subbottom, core samples
Comments 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.
