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
