Title: The nature (speed/direction/persistence) of mud carrying bottom currents entering Granite Harbour to determine the movement
of sediments entering the harbour
The movement of sediment entering Granite Harbour from the Ross Sea was investigated with the nature (speed/direction/peristence)
of mud carrying bottom currents in Granite Harbour determined. The current meter mooring site was identified after a 13 spot
bathymetry measurement some 7km northeast from Discovery Bluff. The mooring site was in the centre of a deep channel trending
north east at 775 m depth. The site was chosen to test if the channel is a conduit for sediment entering the inner harbour
from the Ross Sea. Seven sediment traps from 7m to 730m depth were suspended above the current meter on the mooring.
