Description
The general objective of SponGES 0617 expedition on board R/V Angeles Alvariño (IEO) was the study of sponge grounds in the Aviles Canyon System and Le Danois Bank (Study cases of SponGES project no 4 and 5) where we had knowledge of their existence in the previous projects of IEO in the area (ECOMARG, INDEMARES, ESMAREC), in order to complete the objectives of SponGES project. Specific objectives: 1. Sampling of the structuring sponge species for both anatomical and morphological description and their identification through molecular tools. 2. Collection of samples that will be part of the reference collections, for the sponge grounds species and of the associated fauna. 3. Study of the associated fauna in areas of the target species and in nearby control areas. 4. Sampling of the microbial fauna associated with the target sponge species. 5. Investigate the microbial fauna in sea water collected by rosette and control sediments (Box Corer). 6. Transects with the Politolana ROTV for describing the habitats of structuring species using photogrammetric techniques based on qualitative and quantitative data (presence / density / abundance), as well as environmental data. 7. Sampling for reproductive ecology and genetic structure of target species.
