HFR Surface Currents Extended; Auto-Selection Added
HFR Surface Currents Extended; Auto-Selection AddedPosted July 15, 2013
A recent addition to our high-frequency radio (HFR) antenna arrays has extended the spatial coverage of Voyager’s surface currents overlay for the past month. This relatively new deployment at Kaʻena Point on the northwest tip of Oʻahu extends data along and 200 miles offshore of the southern half of the Waianae Coast (West Coast) of the island. A future HFR deployment on the North Shore is also planned to extend coverage along the north coast as well (no ETA).

In addition, Voyager now provides a new auto-selection utility for the HFR data. This allows the spatial resolution of the surface currents overlay (1, 2, or 6 km) to be automatically selected based on the current map zoom. While the “auto-select” option remains checked, Voyager will continue selecting an appropriate spatial resolution after the map zoom changes.
