Academic, government, and private organizations from around the globe have established High Frequency radar (hereinafter, HFR) networks at regional or national levels. Partnerships been to coordinate collaborate on a single global HFR network (http://global-hfradar.org/ ). These partnerships were in 2012 as part of Group Earth Observations (GEO) promote technology increase data sharing among operators users. The main product are continuous maps ocean surface currents within 200 km coast high...
Abstract Dense arrays of surface drifters are used to quantify the flow field on time and space scales over which high-frequency (HF) radar observations measured. Up 13 were repetitively deployed off Santa Barbara San Diego coasts 7 days during 18 months. Each day a regularly spaced grid overlaid 1-km2 (San Diego) or 4-km2 (Santa Barbara) square, located where HF radial data nearly orthogonal, was seeded with drifters. As moved from they retrieved replaced maintain spatially uniform...
Small, lightweight, and easy-to-deploy Global Positioning Satellite (GPS)-based miniature wave buoys (mini-buoys) are increasing in popularity. Most deployed as Lagrangian drifters, so their utility for engineering applications, requiring a nearshore mooring, has remained question. We evaluated the performance of five moored mini-buoys off coast Duck, North Carolina at Field Research Facility (FRF). collected 8 months data over two deployments; first near FRF's 8-m array then Datawell...
Abstract Sea ice inhibits the development of wind‐generated surface gravity waves which are dominant factor in upper ocean mixing and air‐sea fluxes. In turn, sea properties modified by wave action. Understanding interaction is important for characterizing both interactions dynamics. Current leading theory attributes attenuation primarily to scattering floes. Here we use new situ measurements show that dominated dissipation with negligible effect scattering. Time series height exhibit an...
Historical records of near‐surface water temperatures in the Southern Californian Bight often show a preferential cooling lee headlands such as Point Dume, Palos Verdes, and Loma. At times, this cooler is associated with an increase chlorophyll‐ evident satellite images ocean color from region. Here we combine hydrographic data 1 day cruise aboard RV Roger Revelle (a precursor to 0304 California Cooperative Oceanic Fisheries Investigations (CalCOFI) cruise) high‐frequency (HF) radar (CODAR)...
This paper reports on developing autonomous underwater vehicle (AUV) survey methods for ocean outfall discharge plumes and new insights gained plume mixing. Unique to the study is mapping mixing using colored dissolved organic matter (CDOM) calibrated effluent dilution. AUV mission planning methodologies sampling, characterization onboard temperature, salinity optical sensors, comparison of observational data model results are presented Point Loma Ocean Outfall offshore San Diego, CA. The...
The architecture, status and applications of a realtime data access, distribution, processing storage system designed for networking radial from surface current mapping HF-Radar instruments across the United States is presented. By leveraging design sites, access generalized to nearly all sites while still providing alternate options where needed. Data format convergence, not required, achieved systems through careful metadata code development. Object ring buffers (ORBs) ORB communication...

The U.S. Integrated Ocean Observing System (IOOS®) partners have begun an effort to extend the use of high frequency (HF) radar for Coast Guard (USCG) search and rescue operations all coastal areas with HF coverage. This project builds on success IOOS USCG-supported regional USCG product created by Applied Science Associates (ASA), Rutgers University Connecticut mid-Atlantic region. We describe expanded national product's two main components: optimally-interpolated velocity fields a predicted field.
A monitoring mission to map and characterize the Point Loma Ocean Outfall (PLOO) wastewater plume using an Autonomous Underwater Vehicle (AUV) was performed on 3 March 2011. The mobility of AUV provides a significant advantage in surveying discharge plumes over traditional cast-based methods, when combined with optical oceanographic sensors, capability for both detecting assessing their mixing near far-fields. Unique this study is measurement Colored Dissolved Organic Matter (CDOM) its...
As the US Integrated Ocean Observing System (IOOS) high frequency (HF) radar network (HFRNet) approaches its tenth year of existence, we highlight growth and enhancements that have occurred. High systems measure speed direction ocean surface currents in near real time. Starting with about 30 radars 2005, has grown to over 130 33 participating organizations approximately ten million radial files sent via network. A key component been data ingest, processing distribution system is core...
ABSTRACT Oil-spill fate and transport modeling may be used to evaluate water column hydrocarbon concentrations, potential exposure organisms, impacts of oil spills with without dispersant use. Important inputs for such analyses are current velocities turbulent dispersion coefficients. Fluorescein dye studies off San Diego, California, were calibrate an model by hindcasting movement dye. The spill was then predict subsurface concentrations if dispersed into the under similar conditions....
The U.S. Integrated Ocean Observing System (U.S. IOOS®) is a network of eleven regional ocean observing systems coordinating observations the nation's oceans, coasts, and Great Lakes.
