ObjectivesJoint cruise with Gammarus.

Previous work in the Tamar Estuary by the Institute of Marine Environmental Research had shown that at neap tides, in one reach of the estuary, stratification gave way very rapidly to vertically homogeneous conditions. It was thought that this might have been caused by breaking internal waves. The measurements were aimed at detecting these internal waves and measuring their characteristics.
