05-BMG-SE2 Deep-Sea Sedimentology

Representative Elda Miramontes García

Learning Contents:

Continental margins and deep-sea basins are the largest zones of sediment accumulation in the world. Understanding the sedimentary processes involved in the transport of sediment from the continent to the deep sea has important implications for paleoclimatic and paleoceanographic reconstructions, biogeochemical cycles, ecosystem distribution, geohazards, infrastructure stability and hydrocarbon exploration. This module covers the description of the sedimentary processes and deposits that occur along continental margins and in the deep sea: deposits generated by gravity-driven processes (turbidites and submarine landslides), current-related deposits (contourites), pelagic and hemipelagic sedimentation, and cold water coral mounds. The students will learn to identify these types of deposits from different data sets (multibeam bathymetry, seismic data, sediment cores, well-logging and current measurements).

Learning Outcomes, Targeted Competencies:

1) Recognise deep-sea depositional systems and comprehend the processes that control their formation
2) Identify independently deep-water depositional systems and their evolution based on their sedimentation patterns
3) Understand the role of oceanographic and climatic conditions, ocean productivity and tectonics in deep-sea sedimentation
4) Interprete the type of deep-water sedimentary system based on the combination different data sets (seismic data, multibeam bathymetry, sediment cores and well logs)
