The session will encourage an examination of the teleconnections in the integrated sediment routing systems connecting source and sink, particularly when perturbed by climatic and tectonic mechanisms.

The word ‘teleconnections’ conventionally refers to far-field links between parts of the global climate system. But the ideas underpinning atmospheric and oceanographic teleconnections also apply to the Earth surface systems involving the derivation, transport and deposition of sediment in source-to-sink systems. These sediment routing systems involve vigorous physical and biogeochemical fluxes across and through the Earth's surface and beyond into submarine landscapes. But how do external forcings (climate, tectonics) and internal system dynamics interact in the propagation of signals through sediment routing systems? Can signals in mountainous source regions be recognized in coeval deep marine deposits? Are teleconnections obliterated, transformed in some way, or passed relatively unchanged over the long distances between source and sink?

We invite talks from both modelling and field perspectives tackling all aspects of this exciting problem.
