Abstract
The sea level on the southern Australian coast is examined for the source of the coastal-trapped wave energy observed during the Australian Coastal Experiment. Sea level, adjusted for atmospheric pressure, and atmospheric pressure are observed to propagate eastward at about 10 m s−1. At the lowest frequency examined (24-day period), some energy travels south along the west coast of Tasmania, but does not reach the east coast of mainland Australia, while some energy travels through Bass Strait to reach the east coast of mainland Australia. At the most energetic frequency (8-day period), adjusted sea levels are coherent over the 3700 km of coastline from southern Australia to the east coast, and much of the wind-forced coastal-trapped wave energy appears to travel through Bass Strait to the mainland east coast. We have not identified a mechanism for energy transfer through Bass Strait, and we do not know what fraction of the coastal-trapped wave energy incident on western Bass Strait actually reach...
