Evolution of Ossoue Glacier (French Pyrenees) since the end of the Little Ice Age
Little is known about the fluctuations of the Pyrenean glaciers. In this study, we reconstructed the evolution of Ossoue Glacier (42 degrees 46'N, 0.45 km(2)), which is located in the central Pyrenees, from the Little Ice Age (LIA) onwards. To do so, length, area, thickness, and mass changes in...

Little is known about the fluctuations of the Pyrenean glaciers. In this study, we reconstructed the evolution of Ossoue Glacier (42 degrees 46'N, 0.45 km(2)), which is located in the central Pyrenees, from the Little Ice Age (LIA) onwards.
