The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Near-Real Time Surface Ocean Velocities derived from HF-radar stations located along coastal waters of Puerto Rico/Virgin Islands, eastern US/Gulf of Mexico, Hawaii and western US during January 2015 (NODC Accession 0129913) |
| Abstract: | Maps of ocean surface currents have been identified as cross-cutting observational tools that aid a range of scientific and societal applications, including ecological studies, tracking the fate and transport of pollutants, oil spill response, assessment of beach water quality, search and rescue, maritime operations and tracking changes in ocean climate. High frequency (HF) radar systems measure the speed of ocean surface currents in directions radial to the antenna in near real time. The resulting surface ocean radial velocities are combined with radial velocities collected by neighbouring stations with overlapping coverage to produce real time (total) velocities. Systems operate continuously in all weather conditions and are installed near the coastline. Depending on the desired horizontal resolution of measured currents, the systems are capable of measuring currents anywhere from a 40 to 200 km offshore. Velocities are measured in the upper 0.3 - 2.5 meters of the ocean depending on the operating frequency. Remote sensing of surface ocean velocity from shore-based hf-radar sites bridges the operational observational gap between point samples obtained from in-situ sampling and synoptic scale relatively low resolution data obtained from satellites by providing continuous mesoscale coverage at relatively high resolution near the coast. |
