7. ata buoy is now deployed and operational Sub Surface Deployments Sub surface deployments are used for bottom referencing water quality data Data is bottom referenced when it is collected by sensors that are fixed along a mooring line in a water column that is not free to move vertically As a result water quality data is always collected at a fixed distance from the water body s floor see Figure 10 Sub surface deployments are completed in the same way as surface water deployments However prior to a sub surface deployment it is highly recommended that the MB 100 foam hood be removed This will lighten the buoyancy of the buoy providing a setup that is more stable with less anchor weight Satellite Buoy Sub surface MB 100 deployments are most effective when used along with a larger surface buoy In these configurations the submersed SDL500 data logger acts as a satellite buoy and transmits the sensor data it collects to another SDL data logger on the surface via direct cabling The surface data logger is typically outfitted with a remote telemetry option for automatic data upload capability Standalone Buoy Alternatively MB 100 data buoys can be deployed as standalone systems sub surface For such applications however the entire system including the mooring and 10 SAFELY DEPLOY THE BUOY anchor must be pulled each time batteries need changed or sensors require maintenance or calibration Figure 10 MB 1
