For at undg\u00e5 underafk\u00f8ling, har havpattedyr et tykt sp\u00e6klag som isolerer dem. Selvom det er yderst vigtigt for havpattedyr at beskytte sig mod kulden, er det ogs\u00e5 lige s\u00e5 v\u00e6sentligt at kunne komme af med ekstra varme efter f.eks. en hurtig sv\u00f8mmetur efter byttedyr eller flugt fra rovdyr eller menneskeskabt forstyrrelse. De arktiske hvalarter er yderst tilpassede til livet i det kolde vand. Vandtemperatur i Arktis stiger og de arktiske havpattedyr kan i fremtiden blive temperatur-udfordret i det de risikerer at blive for varme uden at kunne slippe af med overskydende varme. Projektets form\u00e5l er at udvikle en ny dataindsamler som m\u00e5ler narhvalens kropstemperatur kontinuerligt i 4 dage. Dataindsamleren skal fasts\u00e6ttes p\u00e5 ryggen af hvalen. De indsamlede data vil v\u00e6re de f\u00f8rste m\u00e5linger af kropstemperatur af en arktisk hvalart og vil give indblik i, hvor f\u00f8lsomme de arktiske hvaler er i forhold til \u00e6ndringer i vandtemperatur.<\/p>\n<p><strong>Metoder for inklusion af samfundet:<\/strong><br \/>\nProjektet udf\u00f8res i samarbejde med fangere fra Ittoqqortoormiit.<\/p>\n<p><strong>Metoder for formidling overfor samfundet:<\/strong><br \/>\nProjektets resultater vil blive formidlet gennem popul\u00e6rvidenskabelige artikler, podvast samt generel info p\u00e5 Gr\u00f8nlands Naturinstituts hjemmeside.<\/p>\n<p><strong>Projektets start- og afslutningstidspunkt:<\/strong><br \/>\n1. maj 2020 &#8211; 1. maj 2021<\/p>\n<p><strong>Bevilget:<\/strong> 69.000, 00 kr.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Projektleder: Outi Tervo, forsker ved Pinngortitaleriffik \u00d8vrig deltagende: Mads Peter Heide-J\u00f8rgensen, professor ved Pinngortitaleriffik Projektets baggrund, form\u00e5l og forskningssp\u00f8rgsm\u00e5l: Vand har 25 gange bedre varmeledningsevne end luft, hvilket betyder at en varm krop mister varme hurtigere i vand end i luft med samme temperatur.
