Description029f Humpback whale tail at Ísafjarðardjúp (Iceland) Photo by Giles Laurent.jpg |
English: Humpback whale tail (Megaptera novaeangliae) at Ísafjarðardjúp (Iceland). Each whale has unique patterns on its tail, like a fingerprint. Based on a good quality photograph of a whale tail, researchers can identify a specific individual by comparing the photo with a database of photographed whale tails. Using the GPS coordinates and the date of the photograph of each whale tail, it is possible to study the migrations carried out by each individual. Some humpback whales migrate tens of thousands of kilometres in a year. Image set number 6 out of 6.
Français : Queue de baleine à bosse (Megaptera novaeangliae) à Ísafjarðardjúp (Islande). Chaque baleine possède des motifs uniques sur sa queue, à l'instar d'une empreinte digitale. Sur la base d'une photographie de bonne qualité d'une queue de baleine, les chercheurs peuvent identifier un individu spécifique en comparant la photo avec une base de données de queues baleines photographiées. À l'aide des coordonnées GPS et de la date de la photographie de chaque queue baleine il est possible d'étudier les migrations effectuées par chaque individu. Certaines baleines à bosses migrent de dizaines de milliers de kilomètres en une année. Série d'images numéro 6 sur 6.
Deutsch: Schwanz eines Buckelwal (Megaptera novaeangliae) in Ísafjarðardjúp (Island). Jeder Wal hat auf seiner Schwanzflosse ein einzigartiges Muster, das einem Fingerabdruck ähnelt. Anhand eines qualitativ hochwertigen Fotos eines Walschwanzes können die Forscher ein bestimmtes Individuum identifizieren, indem sie das Foto mit einer Datenbank fotografierter Walschwänze vergleichen. Anhand der GPS-Koordinaten und des Datums, an dem die Walschwänze fotografiert wurden, können die Wanderungen der einzelnen Individuen untersucht werden. Einige Buckelwale wandern in einem Jahr Zehntausende von Kilometern. Bildserie Nummer 6 von 6.
Italiano: Coda di megattera (Megaptera novaeangliae) a Ísafjarðardjúp (Islanda). Ogni balena ha disegni unici sulla coda, come un'impronta digitale. Sulla base di una fotografia di buona qualità della coda di una balena, i ricercatori possono identificare un individuo specifico confrontando la foto con un database di code di balena fotografate. Utilizzando le coordinate GPS e la data della fotografia di ogni coda di balena, è possibile studiare le migrazioni effettuate da ciascun individuo. Alcune megattere migrano per decine di migliaia di chilometri in un anno.Set di immagini numero 6 su 6. English: Humpback whale tail (Megaptera novaeangliae) at Ísafjarðardjúp (Iceland).
