PurposeResearch
ObjectivesIn an echosounding survey on 2-3 September 1983 internal waves were observed being generated over topographic features in the estuary during the ebb tide. The internal waves propogate upstream when the current weakens, to eventually break and cause mixing. Repeat surveys were to be carried out at a higher tidal range, and with higher river discharge for comparison with the earlier results. Current measurements would be obtained in addition to salinity and temperature profiles.
