Abstract:

The evolution of continental margins from temperate to polar conditions is still poorly known. There are increasing evidences collected in the Arctic and Antarctic margins that the high sediment input from ice streams produces a phase of margin instability, including catastrophic collapses, before a long lasting equilibrium is reached. The Arctic margins can be regarded as younger, unstable counterparts of mature polar Antarctic margins that began to evolve in the Oligocene-Miocene. We propose an integrated geophysical and sedimentological approach to an Arctic ice stream dominated depositional system from inner shelf to deep sea in order to reconstruct its evolution since pre-glacial times (prior to the Late Pliocene). We chose the relatively small glacial depositional system on the Southern Svalbard margin because it is located in a highly climatically sensitive area of the Northern Hemisphere (narrow gateway to the Arctic ocean), with a small ice catchment and a fairly well known glacial history on land. We propose a 45 days-long cruise on the BIO Hesperides to undertake a full multibeam bathymetric survey of the glacial depositional system, which includes areas of known, but not well-studied slope instability phenomena. Shallow seismics (TOPAS) will provide acoustic facies characterization. Deeper penetration, intermediate resolution multichannel seismic reflection profiles will provide the architectural evolution of the margin using ties to nearby ODP-DSDP holes. The project includes a plan for documentation and dissemination of results through TV and audiovisual products. El conocimiento sobre la evolución de los márgenes continentales de condiciones templadas polares es todavía escaso. Cada vez hay más evidencias, recogidas en los márgenes árticos y antárticos, de que el alto aporte sedimentario incluido por las corrientes de hielo (“ice streams”) produce una fase de inestabilidad del margen que comporta colapsos catastróficos. Esto sucede recursivamente hasta que se alcanza de nuevo un equilibrio duradero. Los márgenes árticos pueden ser calificados como jóvenes e inestables en comparación con los márgenes antárticos, más maduros, que desde el Oligoceno-Mioceno ya comencaron su evolución. Proponemos un estudio integrado, tanto geofísico como sedimentológico, de un sistema deposicional ártico, desde la plataforma interna hasta la llanura abisal, dominado por una corriente de hielo, con el objetivo de reconstruir su evolución desde tiempos pre-glaciales (con anterioridad al Plioceno superior). Se ha elegido un sistema deposicional glaciar relativamente pequeño en el margen meridional de las Islas Svalbard porque está situado en un área climáticamente muy sensible del hemisferio norte (con conexión restringida con el océano Ártico). Este sistema deposicional tiene un área de captación de hielo de tamaño pequeño y una historia glacial bien conocida en tierra. Proponemos una campaña oceanográfica de 45 días de duración a bordo del BIO Hespérides, o equivalente, para obtener cobertura total de batimetría de multihaz del sistema deposicional glaciar, que incluye áreas de conocida, aunque no bien estudiada, inestabilidad sedimentaria. La caracterización del recubrimiento sedimentario superficial se llevará a cabo mediante perfiles de sísmica de muy alta resolución (TOPAS). La evolución de la arquitectura del margen se estudiará mediante perfiles de sísmica de multicanal de resolución media y su correlación con sondeos ODP-DSDP cercanos. El proyecto incluye un plan para la documentación y diseminación de los resultados a través de TV y otros productos audiovisuales.
