The objectives of the DETSUFA cruise (BIO Hespérides 04/03–17/03/2013) are (1) to evaluate the footprint in the seafloor of a series of earthquake-generated subaerial landslides that took place in Fiordo de Aysén, Chile, in 2007, which entered the seawater generating a number of destructive tsunamis which killed 10 and produced significant damage in the local infrastructure, (2) to reconstruct the morphology and dynamics of these landslides in order to obtain input data for tsunami modelling, and (3) to determine the occurrence of similar episodes in the past that might have generated other tsunamis, in order to establish a possible recurrence period of such events. The cruise fits within the global scientific interest stirred up by tsunamis in general, being the Fiordo de Aysén a highly relevant analogue for the understanding of this kind of events occurring in semi-enclosed basins such as fjords, lakes or water dams, which often harbour large human population and infrastructures.

In January 2012, a physical-geological mooring was installed to the East of Elephant Island onboard the RV Hesperides. The mooring was constituted by current meters, temperature, conductivity, and pressure sensors located at selected depths. The mooring was deployed for one year period, and successfully recovered on January 23rd 2013 during the Hesperides Antarctic Survey 2012-2013. The goal of the experiment is to monitor the presence / absence of the Antarctic slope front over the southern slope of the South Scotia Ridge. The addition of a sediment trap will allow to identify the terrigenous / biogenic composition of the flow suspended particles. In an international context, the collected data will be used to optimize the MITgcm Antarctic regional model (ECCO2/ECCO3 project, JPL/Caltech).
