What is COCMP-NC?
Through voter approved Propositions 40 50,
21 million has been directed toward monitoring
coastal currents. The State Coastal Conservancy
is the state agency administering the program.
Two consortia, COCMP-NC in the north and SCCOOS
in the south, are tasked with implementing the
coastal observatory. COCMP-NC was created
because CeNCOOS cant yet receive funding. This
will become a backbone element. Funding is
approved by the Coastal Conservancy Board,
working out the final details on the work
statements. Planning on beginning work in late
fall 2004. http//www.cocmp.org

COCMP objectives
Build a nested array of Surface Current Mapping
Instruments to monitor surface circulation along
the whole California coast between the Mexican
and Oregon borders. Improve the resolution of
coastal surf and wave estimates. Also develop a
tool for estimating longshore and rip currents.
Provide measured and modeled high resolution
meteorological parameters. Provide a 3-D model
of shelf circulation. Have all these data, and
the associated products, available to the public
via an easily accessible web access.

What are SCMI? Also called HF radar and CODAR
No current return
Return with Doppler shift due to
approaching current

COCMP-NC may host the SFPORTS TRIM2D
model Presently operated by Ralph Cheng,
USGS http//sfports.wr.usgs.gov/
and will promote efforts to implement an
operational 3D model.
19
Satellite data are collected by NOAA Coastwatch
and the UCSC Biological and Satellite Oceanograph
y Lab. COCMP-NC will work with these groups.

COCMP-NC
Data and Product distribution will be through the
Real-time Observatories, Applications, and Data
management Network (ROADNet) supported by UC San
Diego (http//roadnet.ucsd.edu). This is a direct
partnership with SCCOOS

COCMP-NC data

• Hourly maps of surface currents
• High resolution maps of wave and surf conditions
• Longshore and rip current estimates
• 3-D modeling of the coastal circulation
• Meteorological observations and models
• All these will be used to generate products!
