    • The Arctic Summer Cloud Ocean Study (ASCOS): Overview and experimental design 

      Tjernström, Michael; Leck, Caroline; Birch, Cathryn E.; Bottenheim, Jan W.; Brooks, Barbara J.; Brooks, Ian M.; Bäcklin, Leif; Chang, Rachel; de Leeuw, Gerrit; Di Liberto, Luca; De La Rosa, Sara; Granath, Eva; Graus, Martin; Hänsel, Armin; Heintzenberg, Jost; Held, Andreas; Hind, Andrew; Johnston, Paul; Knulst, Johan C.; Martin, Maria; Matrai, Patricia A.; Mauritsen, Thorsten; Müller, Markus; Norris, Sarah J.; Orellana, Mónica V.; Orsini, Douglas A.; Paatero, Jussi; Persson, P. Ola G.; Gao, Qiuju; Rauschenberg, Carlton; Ristovski, Zoran; Sedlař, Joseph; Shupe, Matthew D.; Sierau, Berko; Sirevaag, Anders; Sjögren, Staffan; Stetzer, Olaf; Swietlicki, Erik; Szczodrak, Malgorzata; Vaattovaara, Petri; Wahlberg, Nils; Westberg, Maria; Wheeler, Cassie R. (Peer reviewed; Journal article, 2014-03-19)
      The climate in the Arctic is changing faster than anywhere else on earth. Poorly understood feedback processes relating to Arctic clouds and aerosol–cloud interactions contribute to a poor understanding of the present ...

    • Laboratory study of initial sea-ice growth: properties of grease ice and nilas 

      Naumann, Ann-Kristin; Notz, Dirk; Håvik, Lisbeth; Sirevaag, Anders (Peer reviewed; Journal article, 2012-07-10)
      We investigate initial sea-ice growth in an ice-tank study by freezing an NaCl solution of about 29 g kg−1 in three different setups: grease ice grew in experiments with waves and in experiments with a current and wind, ...

    • Recent wind driven high sea ice area export in the Fram Strait contributes to Arctic sea ice decline 

      Smedsrud, Lars Henrik; Sirevaag, Anders; Kloster, Kjell; Sorteberg, Asgeir; Sandven, Stein (Peer reviewed; Journal article, 2011-10-14)
      Arctic sea ice area has been decreasing for the past two decades. Apart from melting, the southward drift through Fram Strait is the main ice loss mechanism. We present high resolution sea ice drift data across 79° N from ...

    • Small-scale dynamics of the under-ice boundary layer 

      Sirevaag, Anders (Doctoral thesis, 2009-01-09)
      In ice covered polar regions, the interaction between ocean, ice and atmosphere is an important component in the complex climate system. Exchange of heat, mass and momentum occurs across the boundary layers, both in the ...

    • Turbulence and heat exchange under ice 

      Sirevaag, Anders (Master thesis, 2003)
      Turbulent fluxes of heat and salt were measured under sea ice at four different locations around Spitsbergen. In Kongsfjorden on West Spitsbergen additional measurements of heat fluxes in the ice and in the atmosphere were ...
