Deployment Overview
In summer of 2011 a SeaSonde® network was
deployed along the Kona coast, providing an
opportunity for scientists in this area to get familiar
with the technology and its surface current and
wave
measurement outputs.
As part of this project, two mid-range SeaSonde
Remote Units were installed, one at the Natural
Energy Laboratories of Hawaii Authorities (NELHA)
and the other approx. 40km north at the Liquid
Robotics facility in Kawaihae harbor. Together they
measure the direction and velocity of ocean surface
currents extending out approx. 85km, with 2-D
current maps produced across their common
overlap
area on a 3km grid. The adjacent images
show the
location of the radars and example of
the current
measurements output.
Data Viewing
This network has been in continuous operation since early August. Animations of the hourly ocean current 2-D maps animations are available for viewing at
http://codar.com/Kona2011/Ocean_Current_Animations.html. New animations will be added routinely throughout deployment period.
Data Access
The actual data files (in ascii format) being collected are available to interested parties who wish to use this data for aiding their research or operational activities. CODAR Ocean Sensors encourages and welcomes such use. Please refer to the
http://codar.com/Kona2011/accessing-data-instructions page for details.
Project Conclusion / Keeping SeaSondes in Hawaii
This demonstration project is scheduled to conclude in late October 2011. We would like to thank our project partners at NOAA Pacific Islands Fisheries Center, NELHA, Liquid Robotics, NOAA U.S. IOOS and PacIOOS for helping in its planning and implementation.
With sufficient funding it will be possible to keep the network in operation, either running as-is, or adapted for better serving a specific need, moved to other locations or set with modified operating parameters. Any interested parties wishing to cooperate for keeping this radar network running in Hawaii, please contact CODAR personnel Chad Whelan at

Mahalo!
