Focus on glaciers: a geo-photo exposition of vanishing beauty

Scientific research, respect for the environment, and passion for photography merged into an exceptional heritage of images collected by the researchers and technicians of the National Institute of Oceanography and Applied Geophysics (OGS). The images were taken during past scientific expeditions conducted all over the world to widen scientific knowledge in the fields of Earth and ocean sciences, to raise awareness on the environment and conservation of natural resources, and to mitigate natural risks.In this paper, we describe a photographic exhibition organized using some of the OGS images to draw public attention to the striking effects of global warming. In the artistic images displayed, the glaciers were the protagonists. Their infinite greyish blue shades and impossible shapes were worthy of a great sculptor, and the boundaries with rocks or with the sea were sometimes sharp and dramatic and sometimes so nuanced that they looked like watercolours.The beauty of the images attracted the attention of the public to unknown realities, allowing us to document the dramatic retreat of the Alpine glaciers and to show the majesty of the Arctic and Antarctic landscapes, which are fated to vanish under the present climate warming trend.The choice of the exhibition location allowed us to reach a broad public of working-age adults, who are difficult to involve in outreach events. The creators of the images were present during the exhibition to respond to visitors' curiosity about research targets, the emotional and environmental context, and the technical details or aesthetic choices of the photographs.
