For more than ten years already, Pauline Delwaulle follows lines, join points, Take planes, borrowing paths, Slip on kayaks, climbing, moves on interactive cards, runs through the world with the fingertips, the measurement, climbing, the film, photography, looking for the right color, The exact brightness, walks towards what she does not know. It is by browsing it that she lives in the land, not by occupying a place, But by actively participating in what is happening there. Close to basic research methodologies, The artist is fascinated by what scientists deploy inventiveness to produce data useful for knowledge. […] The artist tracks for example the researchers of the laboratory of oceanology and geosciences who roam several times a year and after each storm the beach of Dunkirk in order to raise the coastline.
