Narrative: The mapping of the landslides have been carried out base on multibeam bathymetry recorded using Simrad EM12 and Atlas HYDROSWEEP DS multibeam echosounders, during cruises from the Spanish Fishing General Secretary (2003 and 2004) and FAUCES (2018) Project. Morphometric attributes such as slope gradients, profile curvatures, planar curvatures and roughness were obtained by ArcMap (GIS), and topographic profiles allowed us to obtain a better characterization of landslides. Also seismic records with different degrees of penetration (0.5 to 1.5 s) and resolution (from a few metres to decimetres) were analysed for landslide characterization.

This dataset contains the pressure and temperature data acquired by piezometer MAR2-PZML-01 from July 2021 following its deployment during the (MaRoLiS cruise)-[https://doi.org/10.17600/18002394] and its connection to the EMSO-Ligure Nice cabled observatory. Pressure has been measured together with temperature at seven different levels below seafloor as shown in the following table: Image Reference: https://www.seanoe.org/data/00851/96265/illustrations/illustration-192.gif. The P1 and P7 absolute pressure sensors have recorded the ambient pressure of the water column through the seawater-filled interior of the piezometer shaft. The P2 to P6 differential pressure sensors have recorded fluid pressure in the sediment pores relative to the water column pressure.

Repeat hydrography, as organized through the GO-SHIP network, is fundamental for detecting trends and variability also in the Mediterranean Sea. The Mediterranean component of GO-SHIP is MedSHIP, and TAlPro is the western Mediterranean component. The TAlPro2022 cruise consisted of 26 full depth hydrographic stations crossing the Tyrrhenian Sea from north to south, then the Algero-Provencal Basin from south to north. Here the postcalibrated bottle file data are made availiable. Postcalibration has been done by measuring dissolved oxygen and salinity on water samples collected by the rosette. The dataset contains also all chemical variables, measured in the lab.

This dataset contains the pressure and temperature data acquired below seafloor by piezometer SPF-PZ3L since October 2015 following its deployment during the (ESS_PENF50_2015 cruise)-[https://doi.org/10.17600/15010900] . It operated in an autonomous mode until its connection to the EMSO-Ligure Nice cabled observatory on the 14/09/2016. Sediment pore pressure together with temperature have been measured at 20 different levels below seafloor as shown in the following table: Image Reference: https://www.seanoe.org/data/00404/51528/illustrations/illustration-194.gif.

This dataset contains the pressure and temperature data acquired below seafloor by piezometer ST4-PZ2L-01B since January 2014 following its deployment during the (STEP 2014 cruise)-[https://doi.org/10.17600/14005400]. It operated in an autonomous mode until its connection to the EMSO-Ligure Nice cabled observatory on the 14/09/2016.

This dataset gathers, total abundance, abundance per size class, total biomass and biomass per size class of two vulnerable fish species, the dusky grouper, Epinephelus marginatus (Lowe, 1834), and the brown meagre, Sciaena umbra Linaeus, 1758, recorded inside and outside the Marine Natural Reserve of Scandola (Corsica, NW Mediterranean) in 2012 and 2018. Fish were recorded by underwater visual censuses performed on belt transects (50 x 15 m) run parallel to the coast between 1 and 40 m depth at 13 sites according to three levels of protection status (integral reserve, buffer zone and unprotected zone). A total of 532 transects were performed in 2012 and 526 in 2018. Image Reference: https://www.seanoe.org/data/00754/86639/illustrations/illustration-134.gif.

This data set contains underway Temperature, Conductivity, Salinity and Potential Density anomaly data collected by a Thermosalinograph (TSG) during the MedSHIP cruise TAlPro2022 (on the Belgia vessel RV BELGICA) in the Western Mediterranean Sea in May 2022. Underway data was collected along the cruise track with an autonomous TSG system, consisting of a SBE21 together with a SBE38 Thermometer. Both systems worked independent from each other throughout the cruise. While temperature is taken at the water inlet (SBE38), salinity and density are calculated within the interior TSG from conductivity and interior temperature (SBE21)
