SCCOOS Goals and Efforts• Within COCMP, SCCOOS aims to develop
products and procedures—based on observational data—that effectively evaluate and improve ocean management:Step 1: Determine pertinent ocean parameters for data
supported regionStep 2: Develop product(s) based on community
need/usabilityStep 3: Integrate user feedback
• Keys to SCCOOS Efforts– Use of science to produce accurate /comprehensive
description of ocean currents and their respective fields– Working relationships w/CA agency/org reps to define
useable products– Community outreach
Basic Physical Fields• Surface Currents
– Data gathering velocity maps initially based on hi-rez (1km) and long-range (6-10 km) HF radar observations. Evolution to ROMS assimilated models anticipated
– Trajectory analyses based on the spatial surface current information will describe motion of water parcels as a function of time from particular origins.
• Subsurface Currents– Data gathered from COCMP and NOAA gliders; moorings near LJ
and SB and in SMB; as well as OC Water District current profilers will be used to constrain ROMS model
• Surfzone and Nearshore Currents– Interactive websites will provide “nowcasts” of IB & SMB
regions– Southern CA wave momentum stress prediction - as an extension
of CDIP– Month-long observations to provide comprehensive velocity
products (vertical, horizontal, temporal variation)• Products designed for model calibration/validation• 3D maps of nearshore flow
Basic Physical Fields• Subsurface Water Properties
– Density stratification from SCCOOS gliders, moorings and Underway CTD
– ROMS to provide 3D fields: temp, salinity, currents, biogeochemical data
• Sea Level– ROMS sea level “nowcasts” and forecasts as per: baroclinic
and barotropic tides, local winds and remote forcing
• Satellite Observations– Current maps overlays will be produced from observations of
sea surface temperature and ocean color products
• Surface Meteorology– Meteorological property (wind, air temp, humidity) maps to be
available daily @ 3km resolution– Daily report to include 3-days worth of hourly predictions for
So CA Bight
Potential COCMP Product Applications• Water Quality
– Aid in identification of coastal pollution sources• Statistical descriptors, time histories, and trajectory maps
used to gauge transport of bacteria, provide early warning tools, and sampling guidelines
• NPDES discharge plume prediction by coupling EPA PLUMES model to observations and subsurface stratification modeling
• Plume prediction and elimination of known stormwater discharges
– Data gathering from stormwater discharges to determine regional management protocols for fecal bacterial and/or other materials
– So CA water quality agencies - Integration of currently gathered data into the SCCOOS data system
• Southern California Coastal Water Research Project (SCCWRP) Commissioner’s Technical Advisory Group (CTAG)
Potential COCMP Product Applications• Oil Spill Response as well as Search and Rescue
– Meteorological and surface current data gathered and forecasted by COCMP will aid in spill response as well as search & rescue procedures
• Surface currents data and trajectory key to tracking spill region• Wind and wave data helps determine effective deployment of
“operational assets” (booms, spill response vessels, etc.)• Environmental/Meteorological statistics used for spill site risk
assessment• Efficient/Effective determination of spill regions and recovery
assets. SCCOOS products will support federal, state, and local agencies
– Marine Resources & Protected Areas• Statistical descriptions help define egg and larval pathways
connecting coastal marine communities• Tracking and determining likely climate & flow patterns &
variations key to assessing environmental impact on fishery production
Potential COCMP Product Applications• Coastal Erosion
– Data products to aid coastal erosion management depend on COCMP measurements and predictions of the alongshore wave climate and nearshore currents
• Predictive tool to assess storm surge and storm driven erosion rates
• Surf zone current prediction and alongshore sediment transport forecasts can define accretion and erosion regions
• Vessel Traffic Aids– ROMS to provide vessel traffic w/hourly sea level
predictions in sensitive regions• Driven by tides, local winds, and remote forcing
– Real-time observations and predictions of waves, winds, and currents are of practical use to mariners for safe and efficient at-sea operations
