Figure 9. Schematic diagram of CBOS Permanent Monitoring Station, showing full sensor suite and configuration of underwater sensor array. Surface buoy was designed sufficiently large to remain on station for one year, to allow onboard access to electronics, and to serve as platform of opportunity for shorter term sensor experiments. Biofouling and summer anoxia require week servicing of underwater sensors. For this reason, a separate taut wire mooring is deployed adjacent to the surface buoy, and data are communicated via acoustic telemetry.
