How, When and Where Do Ocean Currents Control Sedimentation in Deep-Water Environments?

Explore the intricate relationship between ocean currents and deep-water sedimentation in this comprehensive lecture. Delve into the formation and distribution of contourites, common morphological features along continental margins. Examine the latest research and measurements, including vessel-mounted ADCP data and reanalysis models, to understand the complex interplay between oceanographic processes and sedimentary deposits. Investigate case studies from the Argentina margins and Southern Greenland, and learn about the seasonality and variability of currents. Gain insights into paleocurrent direction determination, sediment supply constraints, and the inversion of bottom currents. Discover the importance of mineralogical analysis in understanding drift locations and formation processes.
