DescriptionBlack ice growler upernavik 2007-07-07a.jpg |
Dansk: Isskosse af sortis fra nyligt kælvet isbjerg nærmer sig land ved den gamle heliport i Upernavik, Grønland. Sortis er frossen smeltevand fra gletcherspalter - dvs. uden luftbobler og derfor gennemsigtig. Sortis er farlig for skibe idet isskosser er sværere at se end almindelige isskosser og de er meget hårde. Efter nogen tid kom den så tæt på at vi kunne fiske den op og studere den nøjere.
English: Black ice growler from a recently calved iceberg closing in on the shore at the old heliport in Upernavik, Greenland. Such black ice growlers originate from gletcher riftf, which has been filled with melting water, which has then frosen into transparent ice without air bubbles. Later we were able to pick up the growler and study it in greater detail.
Français : Un glaçon de glace noire venant d'un iceberg récemment vêlé près du rivage vers l'ancien héliport d'Upernavik, au Groenland. La glace noire provient d'eau qui s'est écoulée dans une crevasse du glacier, puis a gelé, formant une glace sans bulles. Ce glaçon s'est ensuite échoué sur le rivage et il a pu être étudié de plus près. |
