Canyon dynamics
Project Manager: Bill Ussler

The Canyon Dynamics Project is a systematic multi-year study of the physical
processes that occur in the axis of Monterey Canyon. The intention is to
establish how submarine canyons are excavated, to understand the role of
submarine canyons as conduits for transporting materials from continents to the
deep-sea, to determine the rates of these processes, and to assess the
importance of submarine canyons in moving particulate carbon into the deep-sea.
To achieve these objectives four approaches are being conducted simultaneously.
The parallel approaches will allow us to collect the basic data necessary to
define the processes that occur in submarine canyons. They are: (1) Deploy
benthic instrument packages on the canyon floor to establish at least a
three-year record of the energy conditions and to determine the potential for
sediment transport and erosion along the canyon’s axis; (2) Sample of the
channel floor to establish the stratigraphy and source of the most recently
deposited channel floor materials; (3) Repetitively map several small sections
of the channel floor at the highest resolution possible, to determine the
changes that occur in topography of the channel floor; (4) Event response to
sample hyperpycnal flows or other ephemeral sediment transport events within the
canyon.
