      Marini, Simone; Azzurro, Ernesto; Coco, Salvatore; Río Fernandez, Joaquín del; Nogueras Cervera, Marc; Sbragaglia, Valerio; Toma, Daniel; Aguzzi, Jacopo (2016)
      Conference report
      Open Access
      Cabled observatories offer new opportunities to monitor species abundances at frequencies and durations never attained before. When nodes bear cameras, these may be transformed into the first sensor capable of quantifying ...
    • Exo-ocean exploration with deep-sea sensor and platform technologies 

      Aguzzi, Jacopo; Flexas Sbert, Maria del Mar; Flögel, Sasha; Lo Iacono, Claudio; Tangherlini, Michael; Costa, Corrado; Marini, Simone; Bahamón Rivera, Nixon; Martini, Séverine; Fanelli, Emanuela; Danovaro, Roberto; Stefanni, Sergio; Thomsen, L.; Riccobene, Giorgio; Hildebrandt, Marc; Masmitjà Rusiñol, Ivan; Río Fernandez, Joaquín del; Clark, Evan B.; Branch, Andrew; Weiss, Peter; Klesh, Andrew T.; Schodlok, Michael P. (2020)
      Article
      Open Access
      One of Saturn’s largest moons, Enceladus, possesses a vast extraterrestrial ocean (i.e., exo-ocean) that is increasingly becoming the hotspot of future research initiatives dedicated to the exploration of putative life. ...
    • Multiparametric monitoring of sh activity rhythms in an Atlantic coastal cabled observatory 

      Aguzzi, Jacopo; López Romero, David; Marini, Simone; Costa, Conrado; Berry, Alan; Chumbinho, Rogério; Ciuffardi, Tiziana; Fanelli, Emanuela; Pieretti, Nadia; Río Fernandez, Joaquín del; Stefanni, Sergio; Mirimin, Luca; Doyle, J; Lordan, Colm; Gaughan, P. (2020-08-20)
      Article
      Restricted access - publisher's policy
      Cabled video-observatories offer new opportunities to monitor fish species at frequencies and durations never attained before, quantifying the behavioural activities of their individuals, and providing ancillary data to ...
    • Seasonal changes in coastal fish assemblages by multiparametric video-observatory monitoring 

      Fanelli, Emmanuela; Sbragaglia, Valerio; Azzurro, Ernesto; Marini, Simone; Río Fernandez, Joaquín del; Toma, Daniel; Aguzzi, Jacopo (2017)
      Conference report
      Open Access
      Mutiparametric cable video-observatories can offer a great opportunity for the simultaneous monitoring of biotic and abiotic components of an ecosystem, responding to the monitoring strategic needs of the EU Marine ...
    • The Hierarchic treatment of marine ecological information from spatial networks of benthic platforms 

      Aguzzi, Jacopo; Chatzievangelou, Damianos; Francescangeli, Marco; Marini, Simone; Bonofiglio, Federico; Río Fernandez, Joaquín del; Danovaro, Roberto (Multidisciplinary Digital Publishing Institute (MDPI), 2020-03-21)
      Article
      Open Access
      Measuring biodiversity simultaneously in different locations, at different temporal scales, and over wide spatial scales is of strategic importance for the improvement of our understanding of the functioning of marine ...
    • Towards an optimal design for ecosystem-level ocean observatories

      Article
      Open Access
      Four operational factors, together with high development cost, currently limit the use of ocean observatories in ecological and fisheries applications: 1) limited spatial coverage; 2) limited integration of multiple types ...

      Fanelli, Emanuela; Aguzzi, Jacopo; Marini, Simone; Río Fernandez, Joaquín del; Nogueras Cervera, Marc; Canese, Simonepietro; Stefanni, Sergio; Danovaro, Roberto; Conversano, Fabio (Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-21)
      Article
      Open Access
      Deep-sea ecological monitoring is increasingly recognized as indispensable for the comprehension of the largest biome on Earth, but at the same time it is subjected to growing human impacts for the exploitation of biotic ...
    • Tracking fish abundance by underwater image recognition 

      Marini, Simone; Fanelli, Emanuela; Sbragaglia, Valerio; Azurro, Ernesto; Río Fernandez, Joaquín del; Aguzzi, Jacopo (Nature, 2018-09-13)
