Our Planet is Changing We need advanced tools to understand and monitor our oceans, coasts and Great Lakes Zdenka Willis Director, US IOOS Program Office US IOOS®: A Partnership for Lives and Livelihoods

U.S. IOOS: Program Overview 12 Global Component Coastal Component (EEZ to the head of tide) 2 Enhances science and improves decision making 7 Goals, 1 System Improve predictions of climate change and weather Improve the safety and efficiency of maritime operations Improve forecasts of natural hazards Improve homeland security Minimize public health risks Protect and restore healthy coastal ecosystems Sustain living marine resources

Coastal Component Comprised of federal agencies (National level) and non-federal (Regional level) Geographic extent: EEZ to the head of the tide Based on 26 variables Data Management and Communications (DMAC) is a major focus that is intended to be enterprise wide from National to Regional scales 4
5
Observation Networks: Waves Nation’s wave data now accessible –181 platforms in 2008; 227 2011 –Wave Plan called for 296 –New IOOS supported wave sites being deployed collaboratively with USACE/ CDIP program –Some platforms need to be upgraded to directional wave measurements

Inspection of Hyperion Outfall Pipe (never internally inspected for 50 years). Serves City of Los Angeles. One of the world’s largest coastal populations. Close to a billion gallons of sewage to be diverted to an in-shore/shallow outfall. Concern of extent of impact and public health risk in the Santa Monica Bay Hyperion Outfall Diversion November 28-30, 2006

Both offshore and surfzone circulation required observation. HF radar derived surface current map. Surf-zone forecast driven by waves.

Emerging HFR benefits With relevance to EBM, MSP … Mesoscale flow features – large eddies persist at key locations Interannual variability – significant changes in alongshore transport Divergence & convergence (fronts) – interfaces in the ocean Upwelling & phytoplankton – spatial structure of pelagic habitat Larval dispersal & MPAs – population connectivity Juvenile salmon survival – early ocean phase (transport & food) Land runoff plumes – subsidies & contaminants
17
MESOSCALE FLOW FEATURES Can now map, quantify and track features like eddies & jets “Mendocino Eddy” HFR circulation with SST Halle et al 2010 (in review)
18
MESOSCALE FLOW FEATURES Mendocino Eddy … persists year-round. 116W 120W 124W longitude 33N 36N 39N 42N 45N 48N latitude (a) Spring (b) Summer (c) Fall (d) Winter San Francisco Cape Mendocino Point Conception Bjorkstedt et al 2010 (in review)
19
DIVERGENCE & CONVERGENCE (FRONTS) Divergence – regions of persistent surface divergence & upwelling due to wind- driven Ekman transport & flow past topography. Convergence – associated with flow past topography & fronts. Fronts represent high-productivity interfaces … aggregations of plankton, fish, birds, mammals. Upwelling WindsWeak Winds Gough et al 2010 (CWO 2010)

Larval Retention Areas VandenbergAño NuevoPoint LobosPoint Sur Color Map: Location of waters 40 days ago (red), 30 days ago (yellow), 20 days ago (green), 10 days ago (cyan), and 5 days ago (blue) before reaching the labeled MPA (magenta). REFERENCE: B. Zelenke, M. Moline, G. Crawford, N. Garfield, B. Jones, J. Largier, J. Paduan, S. Ramp, E. Terrill, and L. Washburn, “Evaluating Connectivity between Marine Protected Areas Using CODAR High-Frequency Radar,” in Proceedings of the OCEANS 2009 MTS/IEEE Biloxi Conference, Biloxi, MS (2009). Connectivity maps based on measured surface currents show what waters are influencing MPAs and the potential extent of surface water larval transport.
