Ziel der Reise / Objectives of Cruise:

The aim of the expedition is to map and sample a coast-parallel transect and two transects perpendicular to the coast of the Algarve off Portugal. This part of the coast was heavily affected by tsunami inundation exactly 263 years ago on All Saints Day 1755 following a strong earthquake offshore. Deposits of the Lisbon 1755 tsunami have been well studied along the southern Portuguese coast, but the impact of back-wash, the retreating flood into the sea has not been well understood and studied. Mapping and drilling of the sediments is our major goal. We focus on the following scientific questions: Do we find variations in thickness and sediment composition, distribution and preservation of the tsunami layer? What effects on benthic life after tsunami deposition can be observed? Can we develop a tool for the identification of historic and prehistoric tsunami deposits on the shelf? Can we detect predecessor events along the Algarve coast, and obtain information about timing, frequency and magnitude of these natural hazards? Methods: hydroacoustic mapping, gravity coring, vibracoring, grab sampler, micro-plastic net
