Sediment Trap Deployment in the deep Eastern Mediterranean
An autonomously time-series sediment trap that collects the flux of settling particles on an operator-defined schedule is now deployed in the THEMO Mediterranean Sea Observatory in association with a turbidity profiler. The wide top funnel accumulates particulate specimens into individual sample bottles that will be later analyzed in our lab.

Mass transport processes in deep marine environments
Submarine slides are distributed along the continental margin of Israel. To properly constrain the age of a submarine slides, there is a need of samples retrieved either from directly above the slide’s debris or from the slide’s scar which is overlain by hemipelagic sediments.
Efforts were focused on analyzing bathymetric and geophysical data for the mapping of sub-marine slides off-shore Israel. However, their timing and triggering mechanism are only starting to be resolved. Over the past years, our group has been working to address this knowledge gap and date submarine slides along the Israeli margin.

The geological history of the Nile Littoral Cell
The Holocene depositional history of the Nile Littoral Cell was constructed from radiocarbon-dated cores. Sediments derived from the Nile Valley watershed and surrounding deserts provide a records of changes in transport processes and provenance in the past ~8.5 ka cal BP and depicts hydro-climatic events as the African Humid Period and late Holocene Levant aridification.
