"A pair of nets attached to an umbrella-like support. The system was deployed down a 12 cm ice hole and expanded below the undersurface of the ice. A circular motion caused the nets to scrap the undersurface of the ice and collect organisms in the water just below it. There was no flow meter or a description of the net specifications."@en .
