Melt pond formation and temporal evolution at the drifting station Tara during summer 2007
Melt pond coverage of sea ice in the High Arctic was observed for a period of 28 days: from 24 June to 21 July 2007. Pond fractions were computed from digital photographs automatically obtained with a camera and computer unit mounted in the mast of the drifting polar schooner Tara. The area visible...
