Holocene Glacier Variations of Blåisen, Hardangerjøkulen, Central Southern Norway
Abstract A 1-m-deep gully section 460 m beyond the maximum Little Ice Age marginal moraines of Blåisen, Hardangerjøkulen, central southern Norway, revealed alternations of minerogenic and organic sediments. The geographical/geological settings of the dated section provides a unique on/off signal of...
