EDS Projects
Recent EDS Projects Showcase Combination of Technology and Restoration
Efforts. EDS has been fortunate in 2003 to have been rewarded
several projects in the Bay Area and Southern California. From
the wind-swept
playas
of the high desert, to the fog-enshrouded Redwoods of Muir Beach,
EDS is applying state-of-the-art data gathering technologies
in a variety of environmental settings.
Currently, we are conducting field efforts in the Salton Sea, Redwood
Creek and Muir Beach (Marin County), Charleston Slough (SF Bay)
and the Napa Valley. Following are brief summations of these
projects
and the technologies we are using. If you would like to learn more
about
the specifics of our current field investigations please drop us
a line so we may share our insights.
While our current field efforts are steaming ahead, we are already
gearing up for large field efforts this summer throughout San
Francisco Bay. EDS will be working with Wetland and Water Resources
(San
Rafael, Ca) this summer on the Integrated Regional Wetland Monitoring
Pilot
Project.
WWR will be leading a team of investigators (S.F. Estuary Institute,
U.C. Berkeley, Point Reyes Bird Observatory and S.F. State) charged
with accomplishing
2 goals on behalf of CALFED: (1) to evaluate the underlying management
question, how are ecosystem restoration efforts throughout SF
Bay affecting ecosystem processes at different scales; and (2)
through
application
of adaptive monitoring strategy concepts, prepare for subsequent
longer-term monitoring.

Characterization of Shallow Sub-Surface Sediments
of the Salton Sea |
| This on-going field effort
is designed to identify and describe the nature of surface and sub-surface
sediments that would be exposed due to expected future declines in
the level of the Sea. EDS is utilizing state of the art acoustic
technology and processing routines to remotely sense and describe
the Sea bottom. This seabed classification effort is being calibrated
and verified through the collection of over 800 grab samples, 300
core samples and sub-bottom profiling data.
The resulting data set
will be presented in a GIS format. A bathymetric map will first
be constructed from XYZ data. Then a GIS layer containing
seabed classification data (percent sand, silt, clay and gravels)
will be overlaid onto the bathymetric grid. Top of page.

Redwood Creek Sediment Budget Study, Marin County,
California |
|
In order to restore a functional, self-sustaining ecosystem (including
coastal, wetland, aquatic and riparian components), The Golden
Gate National Recreation Area is working to develop a restoration
plan for lower Redwood Creek at Muir Beach, Marin County California.
As part of this plan, EDS is conducting a 2-year sediment supply
monitoring study of the entire Redwood Creek Watershed. This
study includes peak runoff sampling for suspended sediment,
current velocities and bedload transport. A combination of
automated instrumentation and storm-sampling techniques are
being utilized throughout the Redwood Creek Valley.
In addition
to sediment monitoring, EDS recently completed an extensive
survey of the lower reach and Big Lagoon. This survey will be
used for grid construction in a 3-dimensional hydrodynamic computer
model. Top of page.

Charleston Slough Wetland Monitoring, Mountain View,
California |
| EDS is providing on-going monitoring
services for the City of Mountain View that include repeated tidal
slough channel and marsh plain surveys. In addition to surveying,
EDS is maintaining instrument platforms that record data on conductivity,
dissolved oxygen and water surface elevations.
These data will be used for adaptive management decisions
as well as calibration and validation of various hydrodynamic models. Top
