Abstract:

Sand dunes can change location, form or dimensions depending on wind direction and strength. Sand dune movements can be effectively monitored through the comparison of multi-temporal satellite images. However, not all remote sensing platforms are suitable to study sand dunes. This study compares coarse (Landsat) and fine (Worldview) resolution platforms, specifically focussing on sand dunes within the Ubari Sand Sea (Libya). Sand dune features (crest line, dune ridge basal outlines) were extracted from Landsat and Worldview 2 imagery in order to construct geomorphic maps. These geomorphic maps

Abstract:

AbstractThe January 2009 fieldwork season conducted geomorphological and palaeoenviromental surveys in as yet unexplored parts of the Lake Megafazzan Basin, as well as continuing research in the Wadi al-Hayat and Ubari Sand Sea. Lake Megafazzan sediments were investigated at two sites on the eastern margin of the basin. At the first site, east of Tamessah, 24 m of stratigraphy was investigated and found to consist of a lacustrine carbonate unit at the base progressing into a fluvial unit and then an upper carbonate unit. The sediments were sampled for magnetostratigraphy and cosmogenic nucleid

Abstract:

AbstractThis paper presents the first study of phytoliths from the Saharan region. Phytolith analysis shows the potential of reconstructing grassland dynamics during the Holocene, refining our knowledge of palaeoecosystems in the Ubari sand sea, Libya. The lake sediments studied range in age between 3,273–9,440 cal. BP. Tree cover was very low around 3,273–3,436 cal. BP and 6,678–6,796 cal. BP, and the landscape was dominated by C4 grasslands around 6,678–6,796 cal. BP, shifting to a more mixed C3-C4 grassland community around 3,273–3,436 cal. BP. These differences may be caused by the older s

Abstract:

AbstractThe Desert Migrations Project is a new interdisciplinary and multi-dimensional collaborative project between the Society for Libyan Studies and the Department of Antiquities. The geographical focus of the study is the Fazzan region of southwest Libya and in thematic terms we aim to address the theme of migration in the broadest sense, encompassing the movement of people, ideas/knowledge and material culture into and out of Fazzan, along with evidence of shifting climatic and ecological boundaries over time. The report describes the principal sub-strands of the project's first season in
