| En el presente trabajo se estudia la capacidad antioxidante de varios extractos, acuosos e hidro-alcohólicos obtenidos a partir de algas y plantas marinas de la plataforma insular cubana. A todos los extractos se les determinó su contenido de polifenoles, proteínas, lípidos y azúcares totales, así como la actividad Superóxido Dismutasa (SOD). Todos los extractos evaluados mostraron una buena actividad antioxidante, con una CE50 inferior de 0,4 mg.ml-1. El contenido de polifenoles en los extractos de Ulva fasciata es menor el de las otras especies, aunque tanto el extracto hidro-alcohólico como el del alga seca e irradiada de dicha especie presentan una buena actividad antioxidante. El extracto hidro-alcohólico de Thalassia testudinum presenta el mayor... |

| The Owen Fracture Zone is a 800 km-long fault system that accommodates the dextral strike-slip motion between India and Arabia plates. Because of slow pelagic sedimentation rates that preserve the seafloor expression of the fault since the Early Pliocene, the fault is clearly observed on bathymetric data. It is made up of a series of fault segments separated by releasing and restraining bends, including a major pull-apart basin at latitude 20 degrees N. Some distal turbiditic channels from the Indus deep-sea fan overlap the fault system and are disturbed by its activity, thus providing landmarks to date successive stages of fault activity and structural evolution of the Owen Fracture Zone from Pliocene to Present. We determine the durability of relay... |

| The recent discovery of voluminous submarine landslides along the Owen Ridge may represent a source of tsunami hazard for the nearby Oman coast. We assess the severity of this potential hazard by performing numerical simulations of tsunami generation and propagation from the biggest landslide (40 km3 in volume) observed along the Owen Ridge. A finite-difference model, assimilating the landslide to a visco-plastic flow, simulates tsunami generation. Computation results show that Salalah city (190 000 inhabitants) is impacted by 2.5 m-high tsunami waves one hour after sediment failure. Higher wave elevation values (4 m) are reached in the low populated Sawqara Bay over 80 min after slide initiation. Although large submarine failures along remote oceanic... |
