Water masses and circulation in the surface layers of the Caribbean at 66ºW

[EN] A meridional hydrographic section was made in August–September 1997 at 66°W from the coast of Venezuela to Woods Hole aboard the R/V Knorr. In this report, we concentrate on near surface measurements in the Caribbean. The data show two distinct water masses with different origins. From approximately 14°N to Puerto Rico, Caribbean Surface Water and Subtropical Under Water with their source in the North Atlantic are found, as previously observed. From Venezuela to approximately 13°N, a less saline water mass with its source in the Tropics and South Atlantic is found. Within the southern portion of the section, two different velocity patterns are observed, namely, an eastward flow with a subsurface maximum near the coast of Venezuela, and a surface intensified westward jet with Velocities of 130 cm s−1 in midbasin.

Study of the oceanographic conditions in the Caribbean in 2003

[EN]A meridional hydrographic section was made in October 2003 at 66ºW from the coast of Venezuela to Puerto Rico. In this report, we concentrate from surface to 1700 m depth in the Caribbean. The data show two distinct water masses with different origins: Caribbean Surface Water, with salinity values less that 35.5, and Subtropical Underwater (SUW), with subsurface salinity higher than 37, with their source in the North Atlantic and subtropics respectively, as previously observed. Different velocity patterns in the water masses from Atlantic Ocean to the Caribbean are observed. Mass transport through the section is westward and about 30 Sv that matches the transport of the Florida Current.

Lanzarote en la Diputación Provincial durante el sexenio revolucionario (1868-1874)

[ES] Aborda los temas que sobre la isla de Lanzarote plantean sus representantes en la Diputación Provincial, aprovechando la situación creada tras la Revolución de septiembre de 1868. Se realiza un acercamiento al funcionamiento de la institución provincial, el papel que juega dentro de las diferentes instancias de poder y el uso que de ella hacen las fuerzas políticas como mecanismo de control.
