  • Study of quality composition of excavated products from breakwaters constructions in Messinia with final aim of their disposal to the marine recipient.

  • The ClimateFish database collates abundance data of 15 fish species proposed as candidate indicators of climate change in the Mediterranean Sea. An initial group of eight Mediterranean indigenous species (Epinephelus marginatus, Thalassoma pavo, Sparisoma cretense, Coris julis, Sarpa salpa, Serranus scriba, Serranus cabrilla and Caranx crysos) with wide distribution, responsiveness to temperature conditions and easy identification were selected by a network of Mediterranean scientists joined under the CIESM programme ‘Tropical Signals’ (; Azzurro et al. 2010). Soon after, and thanks to the discussion with other expert groups and projects, C. crysos was no longer considered, and Lessepsian fishes (Red Sea species entering the Mediterranean through the Suez Canal) were included, namely: Fistularia commersonii, Siganus luridus, Siganus rivulatus, Pterois miles, Stephanolopis diaspros, Parupeneus forskali, Pempheris rhomboidea and Torquigener flavimaculosus. Considering the trend of increase of these species in the Mediterranean Sea (Golani et al. 2021) and their projected distribution according to climate change scenarios (D’Amen and Azzurro, 2020), more data on these tropical invaders are expected to come in the future implementation of the study. Data were collected according to a simplified visual census methodology (Garrabou et al. 2019) along standard transects of five minutes performed at a constant speed of 10m/min, corresponding approximately to an area of 50x5m. Four different depth layers were surveyed:  0-3m, 5-10 m, 11-20 m, 21-30 m. So far, the ClimateFish database includes fish counts collected along 3142 transects carried out in seven Mediterranean countries between 2009 and 2021, for a total number of 101'771 observed individuals belonging to the 15 fish species. Data were collected by a large team of researchers which joined in a common monitoring strategy supported by different international projects, which are acknowledged below. This database, when associated with climate data, offers new opportunities to investigate spatio-temporal effects of climate change in the Mediterranean Sea and test the effectiveness of each species as a possible climate change indicator.   Contacts: ernesto.azzurro(at)   References: Azzurro E., Maynou F., Moschella P.

  • Species abundance and seagrass cover. Calculated from photo quadrats and video recorded by divers along seabed transects surveyed by divers as part of GENIALG monitoring surveys. Seaweed farm located in Ventry Harbour, Co. Kerry (Ireland). The samples were collected at seven different time points along the growing season in 2018 and 2019. Samples collected as part of the GENIALG project (project ID: 727892, GENIALG - GENetic diversity exploitation for Innovative Macro-ALGal biorefinery, GENIALG was funded by the European Union Horizon2020 programme. The remit of the work was assessing the environmental footprint and ecosystem services provided by seaweed aquaculture in Europe to provide best practice advice to industry.

  • Photographs of marine biodiversity of unknown areas of high ecological value in the Andalusian Litoral, starting at Malaga, where the diving school is located. These studies are delivered to competent authorities for their knowledge and generation of protection figures.

  • Hard substrate benthic communities at offshore wind park turbines poles

  • Continuous measurements (every 10 min) of dissolved oxygen (DO) and water temperature were made with miniDOT oxygen optode loggers (Precision Measurement Engineering, Vista, CA, USA, in the following termed “oxygen logger”) at the three main sites. The chamber incubations were done in triplicates and at the three types of habitat in April, June and August, corresponding to mean temperatures of 9, 16 and 21°C, respectively. Chambers consisted of gas impermeable transparent plastic bags (19 x 42 cm; diameter x height = 12 L) attached to a hard PVC collar, which was secured firmly into the sediment with metal plugs. Incubations were made over a period of approximately 24 hours with logging of oxygen, temperature and light every 10 minutes by a oxygen logger and a light logger placed at a depth of about 30 cm above the seafloor inside each chamber fixed to a metal stick placed into the sediment.
