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.

Amber, sunfish, message in a bottle... Many interesting things are washed upon the Northsea shores. But hardly anyone has recorded so far what is being stranded. Using the Beachxplorer-app you can identify more than 2000 different finds directly on the beach. You can report all these finds to the BeachExplorer database. In case of species that are rare or difficult to identify a proof picture is requested. This allows verification of the determination and serves as proof if you collect observation scores as "species hunter". If you are interested in marine protection you are invited to find additional informations in our web portal www.beachexplorer.org

Verdict
The clearest difference is update cadence: Beach Explorer at every 3 months against OstSeeTiere's every 6 months. Beach Explorer also leads on iOS requirement (11.0 vs 18.6). On price, ads, in-app purchases and device support there is nothing between them.
