Announcement from the Southern California
Coastal Ocean Observing System (SCCOOS)---
27 NOVEMBER 2006
SCCOOS collaborates with City of Los Angeles to provide
environmental data support for the
Hyperion Discharge
SCCOOS was contacted by the City of Los Angeles City of Los Angeles Environmental
Monitoring Division to provide ocean data support for a discharge scheduled
for 28-30 November 2006 one mile off the coast of Santa Monica Bay. Organizations
coordinating the data support for this event include City of Los Angeles Environmental
Monitoring Division, Scripps Institution of Oceanography, University of Southern
California, Jet Propulsion Laboratory, and University of California, Los Angeles.
Surface current maps, derived from an array of HF radars, are being used to
assist in tracking the discharge plume offshore of the beaches. The California
State Coastal Conservancy has funded the installation of the HF radars array
as part of the statewide ocean currents monitoring program, COCMP, with additional
operational support received from NOAA. Wave-driven currents within the surf
zone are being forecasted to provide estimates of how far down-coast the sewage
may move once it reaches shore. The research vessel R/V Seaworld will conduct
boat-based tracking of the discharge plume, in addition to phytoplankton and
nutrient sampling. Remote sensing data from satellites (clouds permitting)
will be made available to optically track the spatial extent of the discharge's
surface plume. Up-to-date wind and rain observations and forecasts also are
being conducted. A link to this environmental data support on the SCCOOS web
site is available here. To learn more about the Hyperion Treatment Plant, click
