Hydrography and flow in the Lucky Strike segment of the Mid-Atlantic Ridge 5
Thurnherr, A. M.; Reverdin, G; Bouruet Aubertot, P; Laurent, L; Vangriesheim, Annick; Ballu, V.
The Lucky Strike segment between 37 and 38N on the Mid-Atlantic Ridge is the focus of the international MoMAR program to monitor seafloor-spreading processes. During the GRAVILUCK cruise in August 2006, hydrographic, velocity and light-scattering data were collected in the rift valley at Lucky Strike in order to investigate the regional dynamics and to provide background information for the monitoring effort. The survey observations reveal a remarkably simple dynamical setting dominated by persistent northward flow transporting approximate to 0.2 Sv of water along the rift valley. Approximately half of this transport must upwell within a deep basin that occupies the northern half of the segment. In the comparatively shallow segment center, the along-valley...

Informe de la investigación de campo de los efectos del tsunami de Japón marzo 2011, en las Islas Galápagos 20
Rentería, W.; Lynett, P.; Weiss, R.; De La Torre, G..
Este informe contiene los resultados de dos campañas científicas realizadas para determinar los efectos físicos del impacto del tsunami de Honshu, japón, sobre las Islas Galápagos. Esta investigación de campo se llevó a cabo en dos etapas, la primera del 7 al 10 de abril y la segunda del 3 al 15 de mayo del 2011, y consistió en el reconocimiento y toma de datos en los puntos más afectados, que fueron determinados de acuerdo al modelamiento numérico, realizado para este efecto.

Injective mappings and solvable vector fields 42
Santos Filho,José R. dos; Tavares,Joaquim.
We establish a sufficient condition for injectivity in a class of mappings defined on open connected subsets of Rn , for arbitrary n. The result relates solvability of the appropriate vector fields with injectivity of the mapping and extends a result proved by the first author for n < 3 . Furthermore, we extend the result to connected paracompact smooth oriented manifolds and show that the convexity condition imposes strong topological restrictions on the manifold.
