A researcher adjusts a 40-inch grid antenna

June 2, 2010
A researcher adjusts a 40 inch grid antenna that will deliver real-time data from Black's Beach to Scripps Pier in La Jolla, California. Scientists from the Scripps Institution of Oceanography's (SIO) Integrative Oceanography Division (IOD) and Woods Hole Oceanographic Institution (WHOI) conducted a two-week pilot study at Black's Beach to examine surf zone water motions in real-time.

More about this Image With assistance from the High Performance Wireless Research and Education Network (HPWREN) team and from the University of California, San Diego, Administrative Computing and Telecommunication Services (ACT) and Office of Network Operations (ONO), several SIO and WHOI scientists deploy two in-situ current and wave measuring stations in shallow water at Black's Beach in La Jolla, California.

These stations are connected to telemetry instruments that are mounted on a steel frame located between the beach and 10 feet of water. At the same time, a 40-inch grid antenna allows the station to deliver real-time data from Black's Beach to Scripps Pier, which utilizes a 180-degree sector antenna. The Internet connection originates at the pier via a wireless Ethernet bridge which telemeters the data in real-time directly to IOD and WHOI laboratories for analysis. The data will allow researchers to better understand beach erosion and near-shore circulation.

The HPWREN project is based on work sponsored by the National Science Foundation's (NSF) Advanced Networking Infrastructure and Research Division under grant number ANI 00-87344. The NSF-funded HPWREN includes backbone nodes on the University of California, San Diego, campus and a number of "hard to reach" areas in San Diego County. The HPWREN provides high-speed Internet access to field researchers from several disciplines (geophysics, astronomy, ecology) including the Black's Beach team, and also provides educational opportunities for rural Native American learning centers and schools in San Diego County.
