  4. Data Users – Continued…. United States Coast Guard - Individual Life Boat Stations – Use real-time current maps for local search planning. - R&D Center – Ongoing demonstrations incorporating real-time and short term forecast current maps into existing Coast Guard search planning procedures. - Oil spill response. NOAA/OP&R/HAZMAT “For this particular incident, we went to the Rutgers CODAR site, to help with the calibration. The web site provided not only data but valuable analysis on the data. Through a phone number provided on the web site I also contacted Josh Kohut who was very helpful in providing additional information concerning the real-time data as well as personal observations of how the coastal currents typically behave off the New Jersey coastline.” - Glen Watabayashi Oceanographer (NOAA/OP&R/HAZMAT) General Public - Recreational and commercial fishing – Use current maps to identify features conducive to fishing. - Surfers – Local wave measurements Local Police - Provide data on an individual case basis to aid in ongoing investigations. National Weather Service - Track passing weather systems - Wave data incorporated into rip-tide forecasts.

  34. Summary • A wide variety of users from research scientists to the general public • benefit from surface current maps and wave data. • HF Radars Work! • There is a frontal feature that follows the Hudson Canyon out to the • mid-shelf that varies over seasonal scales. • Current maps near the mouth of New York Harbor show strong • correlation between local winds and the direction of freshwater outflow. • NEOS: 18 systems and growing…
