Short summary
The Tunisian coast has been historically affected by extreme marine submersion events resulting from storms or tsunamis. To establish adaptation and mitigation strategies, it is essential to study these events in terms of spatial and temporal variability. Using a geological archive (sediment cores and surface sediments) retrieved from this coastal area of Tunisia, we present a reconstruction of past marine submersion events over the last 2500 years.

We analyze marine sedimentary records to study temporal changes in oxygen and productivity in marine waters of central Chile. We observed increasing oxygenation and decreasing productivity from 6000 kyr ago to the modern era that seem to respond to El Niño–Southern Oscillation activity. In the past centuries, deoxygenation and higher productivity are re-established, mainly in the northern zones of Chile and Peru. Meanwhile, in north-central Chile the deoxygenation trend is maintained.

Amongst the most devastating marine catastrophes that can occur in coastal areas are storms and tsunamis, which may seriously endanger human society. In a sediment core from the Mar Menor (SE Spain), we discovered eight coarse-grained layers which document marine incursions during periods of intense storm activity or tsunami events. These periods of surge events seem to coincide with the coldest periods in Europe during the late Holocene, suggesting a control by a climatic mechanism.

Short summary
High-resolution pollen analyses undertaken on two cores from southern France allow us to separate anthropogenic effects from climatic impacts on environments over the last 4500 years. A long-term aridification trend is highlighted during the late Holocene, and three superimposed arid events are recorded around 4400, 2600 and 1200cal BP coinciding in time with Bond events. Human influence on vegetation is attested since the Bronze Age and became dominant at the beginning of the High Middle Ages.

Short summary
The past flood activity was investigated using a sedimentological and geochemical analysis of surfaces sediments from a southeastern Tunisian catchment in order to trace the origin of sediments deposit in the El Bibane Lagoon. Aeolian, fluvial and marine source. This multi-proxy analysis on the BL12-10 core shows that finer material, a high content of clay and silt, and a high content of the elemental ratios Fe / Ca and Ti / Ca characterise the sedimentological signature of palaeo-flood levels.
The past flood activity was investigated using a sedimentological and geochemical analysis of...
