| Abstract: | Four New Zealand fjords were surveyed in March and April 1980. In Milford Sound, unusually low dissolved oxygen levels in Stirling Basin suggests that intermittent stagnation events occur, while in Deep Water Basin the bottom water was virtually anoxic. Near the entrance to Milford Sound aperiodic currents up to 38 cm s?1 were recorded. In Isthmus Sound and Long Sound, in Preservation Inlet, contrasting circulation and mixing regimes were found and tidal currents up to 60 cm s?1 over the entrance sill to Long Sound are important for deep water renewal. |
