Maya Lin, Waterline, 2006, aluminum tubes.
Water Line is a spatial/sculptural line drawing of a particular underwater location on ocean floor along the Mid Atlantic Ridge. The site rises a few miles from the sea floor and is visible on the surface as Bouvet Island, one of the most remote islands in the world. Working with scientists at Woods Hole Oceanographic Institute, Lin and members of her studio, developed a topographic rendering of the seascape. The rendering was translated into a metal drawing suspended above the viewers.
