COCMP Monterey Bay - Elliptical Sites Page

Elliptical measurements differ from radial measurements in that a transmitter that is some distance away from a receive antenna is used. Radial measurements, if a transmitter is located at the same place as the receive antenna, can still be performed, but the benefit of performing ellipticals in acheiving greater coverage and longer range.
The transmit for the elliptical measurement needs to be synchronized with the receiving system and thus the need for GPS synchronization. Typically one SeaSonde system is set up to listen while others broadcast for it. It is not limited to one sychronization but is limited in distance, and ultimately is still has yet to be shown its value as a real-time source of surface current measurements.

Ocean currents maps are a product of the Coastal Ocean Currents Monitoring Program (COCMP). The project is funded by the State of California from the California Clean Water, Clean Air, Safe Neighborhood Parks, and Coastal Protection Act of 2002 and the Water Security, Clean Drinking Water, Coastal and Beach Protection Act of 2002. In this region, the project is coordinated through the Central and Northern California Ocean Observing System (CeNCOOS) and is supported by the Center for Integrated Marine Technologies.
