Turbidity maximum formation in a well-mixed macrotidal estuary: The role of tidal pumping

It is proposed that an ice shelf disintegrates when its calving front retreats faster than its grounding line. This paper examines the role of ice thinning in grounding-line retreat. Thinning occurs as a result of creep spreading and ice melting. Thinning by creep is examined for the general regime of bending converging flow in an ice shelf lying in a confined embayment, and at the grounding lines of ice streams that supply the ice shelf and ice rises where the ice shelf is grounded on bedrock. Thinning by melting is examined at these grounding lines for tidal pumping and for descent of surface melt water into strandline crevasses, where concentrated melting is focused at the supposed weak links that connect the ice shelf to its embayment, its ice streams, and its ice rises. Applications are made to the Ross Ice Shelf.

Samples of suspended particles have been collected from the turbidity maximum region of the Tamar Estuary, S.W. England. Specific surface areas and porosities of the particles were determined by a BET nitrogen adsorption technique. The role of surface coatings of organic matter and Fe and Mn oxides was examined. The data show that the specific surface area was highest at the turbidity maximum and was associated with high Fe/Mn ratios. The characterised particles were then used in time-dependent adsorption-desorption experiments, with waters from the metal-rich Carnon River, S.W. England. The rates and extents of the sorption processes were interpreted in terms of a two-stage reaction which was related to the microstructures of the particles. Kinetic analyses of the desorption profiles gave rate constants which are of significance in the prediction of the fate of toxic metal wastes discharged into estuaries.
