Mit dieser App können Sichtungen und Totfunde von Meeressäugetieren der Ostsee, wie den bedrohten Schweinswalen (IUCN Rote Liste) und den Robben (Kegelrobbe, Seehund und Ringelrobbe) gemeldet werden. Alle gemeldeten Sichtungen werden der Öffentlichkeit in einer interaktiven Karte zugänglich gemacht. Gemeldete Totfunde an der Küste Mecklenburg-Vorpommern werden durch das Deutschen Meeresmuseum (DMM) in Stralsund geborgen und eingehend auf Gesundheitszustand und Todesursache untersucht. Diese Daten werden vom DMM wissenschaftlich ausgewertet, interpretiert und ergänzen dadurch weitere wissenschaftliche Methoden zur Erforschung der Meeressäugetiere, wie der Flug- und Schiffzählung und den akustischen Lautaufnahmen. Mithilfe dieser gesammelten Daten können Gebiete in der Ostsee, welche von besonderer Bedeutung sind, z.B. für die Aufzucht bzw. Geburt von Schweinswalkälbern, lokalisiert werden. Des Weiteren dienen die Daten für die Erhaltung und ggfs. Erweiterung bestehender Schutzkonzepte.
