The objective of the project was the investigation of englacial melt water channels of Svalbard glaciers in order to find in situ organic material within glacier caves. Specified organic material found beneath glaciers was meant for radiocarbon dating and creation of reliable geochronologies of glacier recessions with considerable smaller glacier termini than present on Svalbard. First radiocarbon dating results ever from organic material found under a glacier’s bottom of glacier Longyearbreen will be published this year. The different moss species ranging from Tomentypnum nitens, Sanionia uncinata, Distichium spp., Syntrichia ruralis gave ages between 1900 and 1100 cal yr BP (Humlum et al., 2004).
