The Land/Ocean Biogeochemical Observatory (LOBO) is an ongoing project designed to quantify the biogeochemical processes of a
coastal ecosystem by the development and operation of an {\it in situ} sensor network in Elkhorn Slough, California. The
primary goal is to design and operate autonomous moorings that measure ambient nutrient concentrations and standard water
properties at appropriate spatial and temporal scales to investigate the biogeochemical processes of an estuarine
environment. The embedded network relies on newly developed instruments that are capable of high resolution, long-term
measurements of nitrate, ammonium, phosphate, and silicic acid. Sensor network design, calibration and operation of the
instrumentation, and real-time data collection via a wireless network have been accomplished. A nearly continuous dataset
from the first year of operation in Elkhorn Slough demonstrates many of the advantages of using {\it in situ} instruments to
study biogeochemical cycles in aquatic systems. The sensor network can address the practical challenges of studying
complicated nutrient cycles, tidal mixing, and small-scale physical variability that are faced in coastal biogeochemical
research and monitoring.
