| 2 ponds (or lagoon) were studied in order to establish the economic possibilities of their exploitation for oysters. Bathymetric and sediment maps were produced using methods described. They indicate a morphological similarity between the ponds, with a superficial broken bed and a regular, flat or gently sloping bed beyond 7 m, the general form reflecting the aerial relief of the adjacent `coast'. The deeper regions had mud or clay sediment, while the edges of the ponds were covered with sand. In more detailed studies it was evident that the banks of Diane were more regular and steep than those of Urbino, and that only in the latter was there a good relationship between the depth of water and the carbon/nitrogen ratio. Differences are thought to relate to... |

| Only fifteen or so years ago, the geology and sedimentology of the Gulf of Gascony was not at all well known. Dredging was rare and the only systematic readings of the nature of the sea beds were given by the Hydrographic Service's probes. It is based on this information that DELESSE (1872) made the lithologic map of the French seas, revised and supplemented by THOULET in 1904. In 1955, BERTHOIS published the first summary research. He used dredgings from various campaigns, Pourquoi-Pas?, Quentin-Roosevelt, President Theodore Tissier, and resumed the previous research work of DANGEARD (1928), FURNESTIN (1937) and BERTHOIS (1946). He classified the collected sediments according to the shape of their cumulative curve, their average diameter and created a... |
