ABSTRACT:
Synthetic seaweed for underwater installation comprises an elongate anchor and at least one sheet of flexible material adjacent the anchor. Fastening means secures a first edge portion of the sheet to the anchor along at least a portion thereof so that the sheet extends outwardly therefrom terminating at an outer boundary edge portion. Perforations are provided in the sheet whereby resistance of the sheet to underwater currents is reduced. The sheet may be cut into strips and buoyant material may be associated with the seaweed in its sheet or strip forms to increase the buoyancy of the finished product. In use, the anchor rests on the bottom of the sea and the submerged flexible sheets or strips extend upwardly therefrom. These sheets or strips sway in the ocean water thereby reducing currents in the surrounding water which promotes marine life and/or permits accretion of suspended sand and sedimentation of solid particles.
