Í stillunum undanfarnar vikur hefur vaxið mikið af kísilþörungum á botni Mývatns. Þegar hreyfir vind flýtur mikið af þeim upp og safnast í skánir í víkum og vogum. Hér er ein slík skán í Garðsvogi í dag.
In the last weeks the weather has been very calm and diatoms have been growing uninterrupted on the bottom. When the wind blows a lot of them float to the surface and form a thick layer. This picture was taken an hour ago in Garðsvogur on the south side of Myvatn.
