(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-19)
      For more than five decades, research has been conducted at Ny-Ålesund, in Svalbard, Norway, to understand the structure and functioning of High-Arctic ecosystems and the profound impacts on them of environmental change. Terrestrial, freshwater, glacial and marine ecosystems are accessible year-round from Ny-Ålesund, providing unique opportunities for interdisciplinary observational and experimental ...

    • Optical properties of snow and sea ice field measurements, parameterization schemes and validation 

      Pedersen, Christina Alsvik (Doctoral thesis; Doktorgradsavhandling, 2007-12)
      Optiske Egenskaper av Snø og Sjøis: Felt målinger, Modellbeskrivelse og Validering av Modeller I dag hersker det liten tvil om at de raske temperatur endringene vi er vitne til er menneskeskapte. Temperaturen øker dobbelt så hurtig i Arktis i forhold til i resten av verden, med den konsekvensen at sjøisen i Arktis smelter med akselererende hastighet. Klimamodeller kan beskrive fortidens, nåtidens ...

    • Regional melt-pond fraction and albedo of thin Arctic first-year drift ice in late summer 

      Divine, Dmitry V; Granskog, Mats A.; Hudson, Stephen R.; Pedersen, Christina Alsvik; Karlsen, Tor Ivan; Divina, S.A.; Renner, Angelika; Gerland, Sebastian (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-09)
      The paper presents a case study of the regional ( ≈ 150 km) morphological and optical properties of a relatively thin, 70–90 cm modal thickness, first-year Arctic sea ice pack in an advanced stage of melt. The study combines in situ broadband albedo measurements representative of the four main surface types (bare ice, dark melt ponds, bright melt ponds and open water) and images acquired by a ...
