The use of ocean buoy systems for long-term science observations at the sea surface and in the upper water column is a well established data-collection technology. Utilizing solar energy or battery storage for instrument power and line-of-sight radio or over-the-horizon satellite communications has allowed buoy-based observatories to offer near real-time data and instrument status information to be transmitted back to researchers on shore.

In addition to making time-series measurements of the physical, biological, and chemical processes, this information is useful for detecting episodic events in real time, such as the onset of local coastal upwelling and can be utilized to coordinate and provide a long term context for shorter duration scientific expeditions. The ability to check instrument health status in near real-time is also invaluable for maintaining a reliable data stream and scheduling maintenance.

MBARI has been operating a buoy system known as OASIS with these capabilities in the Monterey Bay region for nearly a decade collecting valuable time-series data using a continuously upgraded suite of upper water column instruments.
