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 region Step 2: Develop product(s) based on community need/usability Step 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 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
