The associated data highlights the sampling programme for the data acquisition campaign of Observation on the Aerial Platform for the SAMM1campaign (Aerial Marine Megafauna Monitoring) conducted by the PELAGIS observatory.

Eunis-classified physical habitats physiques resulting from the combination of three physical variables meshed at a resolution of 250 metres: nature of the substrates, biological area, shearing tension on the sea floor.

The In Situ Analysis System (ISAS) was developed to produce gridded fields of temperature and salinity that preserve as much as possible the time and space sampling capabilities of the Argo network of profiling floats. Since the first global re-analysis performed in 2009, the system has been extended to accommodate all types of vertical profile as well as time series. ISAS gridded fields are entirely based on in-situ measurements. The system aims at monitoring the time evolution of ocean properties for climatological studies and allowing easy computation of climate indices. A careful delayed mode processing of the 2002-2015 dataset has been carried out using version 7 of ISAS and updating the statistics to produce the ISAS-15 analysis.

Occurrence rate by observation number for 100km of effort in each 40km mesh in the French mainland EZE in the winter of 2011/2012 and the summer of 2012.

Occurrence data of strandings of marine mammals collected by the correspondents of the National Stranding Network (date, position, species) in metropolitan France in 2014-2020.

This bathymetric model is the result of compiling data and numerical models prior to 2008 in the Bay of Biscay. These datasets are available at a resolution of 500 m and 1000 m. Contours are also available for both digital terrain model (DTM). Public access granted under certain conditions.
