Reference application form 442 files: 0161-EX-PL-2005 Research Objectives: Mapping of the ocean surface currents along the Oregon coast is the primary objective. This research is on going, hence the request for a 5 year license. Present funding (grant #0237710 below) extends through the year 2008. Pending proposals extend research objectives to the year 2010. Research conducted under the following National Science Foundation grants: Grant# 9907854 Collaborative Research: Coastal Ocean Advances in Shelf Transport (COAST) 0237710 Collaborative Research: Productivity, Biogeochemical Transformations and Cross-Margin Transport in an Eastern Boundary Buoyant Plume Region 0000734 Collaborative Research: GLOBEC: Mapping the Evolution of Mesoscale Jets and Eddies in the Upwelling Ecosystem off Cape Blanco, Oregon, Using Long-Range High Frequency Radar Fee Exempt: This research is being sponsored by federally funded research grants to a public university, and as such should be considered fee exempt. Technique: The equipment measures ocean currents using the echoes of radio waves scattered continuously from ocean waves. The received radio waves are shifted in frequency by the combined effects of ocean waves and ocean currents. The known properties of the ocean waves are then subtracted, leaving the effects of the ocean currents.

For clarification requested frequencies (seven total) are listed here: Frequency Station Class Output Pwr/ERP Mean/Peak Frequency Emission Modulating MHz Tolerence Designator Signal 12.06 FX 90W/40W P 0.0010% 170KP0N FM Sweep 12.14 FX 90W/40W P 0.0010% 170KP0N FM Sweep 12.20 FX 90W/40W P 0.0010% 170KP0N FM Sweep 13.46 FX 90W/40W P 0.0010% 170KP0N FM Sweep 13.51 FX 90W/40W P 0.0010% 170KP0N FM Sweep 13.57 FX 90W/40W P 0.0010% 170KP0N FM Sweep 13.63 FX 90W/40W P 0.0010% 170KP0N FM Sweep
