| At the same time as the technological developement of a new deep-sea tide gauge, taking advantage from the work of Eyries [I], scientific studies on the off-shore tides are carried at the Oceanographic Center of Brest. First of all, we made a rapid survey on tide at the limit of the littoral part of the Gulf of Biscay. The positions of the six stations on the bathymetric line of 200 meters are given by the fig. I. The current measurements were made by Aanderaa currentmeters and those regarding the variation of the sea level by a prototype of the french tide gauge using a differential manometer with vibrating strings. The measurements lasted for about two days. During this period, the semi-diurnal tide is represented by the M2 component of a period T? =... |

| In this schema of solar ponds, a limited shallow marine area overlays a dark layer where the solar radiation is absorbed. The interna1 thermal convection phenomenon due to heating is cancelled by the action of an adequate vertical density gradient created by salt dissolving. This gradient has to be kept up against the saline dif fusion. Previous experimentation, in Israël for the main, had shown that, after a long enough period of transition to normal running, high temperatures on the bottom of the order of 90°c, can be obtained. CNEXO, the French National Center for the Exploitation of the Ocean, is interested in trying to transform isolated marine natural areas into solar ponds with power order of 100 kW. An experimentation has been launched to specify... |
