Underwater Landslides off Southern California
An earthquake can trigger a landslide along the ocean floor, which can then set off a tsunami. Without modern, high-resolution imaging of the seafloor, many historical slides and threats from future slides remain undetected.
Sediment transport in submarine canyons
Objectives: Produce a step-change in understanding of submarine turbidity currents by measuring their two key features (synchronous velocity and concentration profiles) in detail (every 2-to-30 seconds) for the first time, and documenting spatial changes in their flow velocity from source-to-sink for the first time.
Coastal and Marine Geohazards of the U.S. West Coast and Alaska
Coastal and marine geohazards are sudden and extreme events beneath the ocean that threaten coastal populations. Such underwater hazards include earthquakes, volcanic eruptions, landslides, and tsunamis.

Streamer Depth Control Birds
The Geospace Navigator bird is a streamer depth control device, used with a high-resolution seismic system to regulate and record the depth of the streamer.
