is Source-to-Sink (S2S)?
Most of the events that shape the Earth's
surface both above and below sea level leave a record of their
the sediment sequences that accumulate on continental margins.
Yet, despite decades intensely studying sedimentary systems,
much remains to be understood. The overarching goal of the MARGINS
Source-to-Sink initiative is to develop a quantitative understanding
of margin sediment dispersal systems and associated stratigraphy.
A predictive capability for dispersal-system behavior has critical
implications for understanding geochemical cycling (e.g., carbon),
ecosystem change (tied to global warming and sea-level rise),
and resource management (e.g., soils, wetlands, groundwater,
and hydrocarbons). The Source-to-Sink Focus Initiative aims
to address the following fundamental questions:
- What processes control the
rate of sediment and solute production in a dispersal system?
does transport through the system alter the magnitude, grain
size, and delivery rate to sediment sinks?
- How is variability
of sediment production, transport, and accumulation in a
dispersal system preserved by the stratigraphic
