Figure 13.  Mugu Canyon subsurface mooring diagram (mooring 839) illustrating the locations of the three sediment traps at 30, 60, and approximately 100 above the sea floor. The drawing is not to scale. Oceanographic instrumentation attached to the 122-m long mooring line (similar to the Hueneme Canyon mooring) was selected for the collection and recording of pressure, temperature, and turbidity measurements in the water column: ADCP-acoustic Doppler current profiler; Mc-Microcat conductivity/temperature recorder, Br-Brancker multichannel data recorder, Tr-transmissometer/turbidity sensor, Trap-Anderson sediment trap.
