Purpose
|
|
1) Mechanics and timing of submarine sediment failures on part of the
|
|
mainland slope of the Santa Barbara Channel (piston coring). 2) Neotectonics
|
|
and timing of recent fault movement in the inner California Continental
|
|
Borderland from Anacapa Island to San Diego, CA (piston coring and gravity
|
|
coring). 3) Stratigraphic and sedimentologic characterization of offshore
|
|
facies that comprise part of the onshore coastal aquifer systems contaminated by
|
|
salt water intrusion (vibracoring). 4) Mass balance of contaminants
|
|
(chlorinated hydrocarbons and trace metals) associated with sediment deposited
|
|
on the Los Angeles margin (Pt Dume to Huntington Beach, CA) (box coring).

Summary
|
|
The M/V Auriga left the port of Redwood City at 0800 on July 18, 2003,
|
|
and returned to the Port of Redwood City at XXXX on July 31, 2003. Transit to
|
|
the operation area in the Santa Barbara Channel took approximately 28 hours.
|
|
The return transit from Santa Monica Bay took approximately 38 hours. During
|
|
our 11 operational days we collected 29 piston cores, 25 gravity cores, 43 box
|
|
cores, and 19 vibracores. We also collected 3 hours of CHIRP high-resolution
|
|
seismic-reflection data in support of the vibracoring operations.
|
|
A piston core collected at site Hein1, a station positioned to sample for
|
|
seafloor discharges of methylmercury, recovered an ice sample of gas hydrate.
|
|
To our knowledge, this is the first discovery of gas hydrate south of the
|
|
Mendocino Triple Junction.
