Lichen Growth on Supraglacial Debris and its Implications for Lichenometric Studies

  • Nigel J. Griffey (a1)

Abstract

Lichens were found growing on some of the supraglacial debris of six small, active, retreating valley glaciers in southern Norway. The circumstances permitting their growth are discussed, as is the possibility of their surviving pro-glacial deposition under current and past conditions. Their occurrence does not appear to present a problem to careful lichenometric surveys of Holocene glacial and fluvio-glacial deposits.

Résumé

Croissance des lichens sur des blocs supraglaciaires et conséquences pour les études lichenométriques. On a trouvé des lichens en cours de croissance sur quelques moraines supraglaciaires de six petits glaciers de vallées actifs en retrait, dans le Sud de la Norvège. On discute les conditions ayant permis cette croissance ainsi que la possibilité qu'ils aient survécu après un dépôt proglaciaire sous les conditions régnant autrefois et actuellement. Leur présence ne semble pas poser un problème pour les observations lichénométriques minutieuses des dépôts de l'Holocène, glaciaires et fluvio-glaciaires.

Zusammenfassung

Flechtenwachstum auf glazialem Oberflächenschütt und seine Bedeutung für lichenometrische Studien. Der Schutt auf sechs kleinen, aktiven, zurückgehenden Talgletschern in Südnorwegen ist teilweise von Flechten bewachsen. Die Umstände, die dieses Wachstum ermöglichen, werden diskutiert, darunter die Frage, ob die Flechten eine voreiszeitliche Ablagerung unter derzeitigen und früheren Bedingungen überleben können. Ihr Auftreten scheint kein Problem für sorgfältige lichenometrische Messungen auf holozänem glazialem und fluvioglazialem Schutt zu bieten.
