Wave Glider “NC2” And Hurricane Ana

Wave Glider “NC2” And Hurricane Ana

Track the “NC2” wave glider mission from Liquid Robotics, Inc. in near real-time as it measures wave heights in Hawaiʻi during Hurricane Ana. NOAA’s Central Pacific Hurricane Center (CPHC) predicts that Ana will reach Hawaiʻi Island by Friday night (October 17) the rest of the main Hawaiian Islands over the weekend. Heavy rains, high surf, and damaging winds are expected. Starting off the leeward (western) coast of Hawaiʻi Island on September 11, this unmanned ocean robot is transmitting measurements at the ocean’s surface. Every half hour it records wave height, wave direction, and wave period. It is currently (Oct. 17) located 14 miles (23 km) offshore of North Kohala on the leeward side of Hawaiʻi Island.

You can follow NC2 using the “ocean gliders” category in PacIOOS Voyager and selecting the NC2 glider mission. Use this to plot or animate the glider’s motion over time. Click on a location to see its wave measurements. Other Voyager overlays of interest during Ana include GOES satellite cloud imagery, Doppler radar, wind forecasts, rain and stream gauges, and wave buoys.

PacIOOS is the first regional association that was certified as a Regional Information Coordination Entity (RICE) by the U.S. Integrated Ocean Observing System (IOOS). Certification provides NOAA and its interagency partners a means to verify that a regional association’s organizational and operational practices, including data management, meet recognized and established standards set by NOAA.
