avvistAPP is a free citizen science tool that allows everyone to actively contribute to the monitoring of marine animals. This app was initially designed to monitor the spreading of the invasive ctenophore Mnemiopsis leidyi in the Gulf of Trieste, (North Adriatic Sea, Italy) but can be used also to collect sightings of jellyfish, sea turtles and dolphins. avvistAPP is availble in Italian and English and is operative at global scale.

The user can find in avvistAPP pictures and short descriptions of the targeted animals.Spatial and temporal coordinates are added by the app. The coordinates are not the precise coordinates of the organism, but the coordinates of the device reporting the sighting. Therefore, in case of coordinates on land it means that the user reported from the coast. The sightings (possibly with a photo) are verified by marine biology researchers in OGS (for turtles and dolphins OGS collaborates with the non-profit association DelTa (Delfini e Tartarughe dell’Adriatico)). The data originator will be updated with the reception and the validation of his/her sighting. These data are collected and analyzed by OGS researchers and are available to the entire scientific community in order to better understand the state of our sea. The validated datasets are processed by data managers in the Italian NODC and provided also to major European infrastructures as open data. Direct links will be added in a later version of this document.

avvistAPP was developed in Italy during 2019 by National Institute of Oceanography and Experimental Geophysics - OGS and Divulgando Srl. It was funded by the ‘Regione Autonoma Friuli Venezia Giulia’ (l.r.n. 14/2018, art. 2 commi 51-55 and n. 26/2020, art. 4 commi 33-34) in the scope of the project ‘Noce di mare’.
