Land/Ocean Biogeochemical Observatory (LOBO) in Elkhorn Slough and Monterey Bay OverviewTeamPublicationsTechnologiesData The Land-Ocean Biogeochemical Observatory (LOBO) consists of robust moorings that can withstand tidal currents and weather. The moorings are highly configurable, can be deployed in waters as shallow as 0.5 m, are relatively easy to maintain, and accommodate a complete array of standard and novel sensors. The sensors communicate with an on-board controller which relays data to shore in near-real time. LOBO moorings have been simultaneously deployed and maintained since November 2003. Continuous hourly data of biological, chemical, and physical properties are relayed to shore, processed, and disseminated to users through a web interface in near-real time.The instrumentation in the LOBO project is a combination of commercially available and ‘in house’ technology. Combined with a mooring system that allows for long term deployment and rapid data transmission through a wireless LAN, the sensors can return near-real time information for extended deployment periods.
