The Mediterranean Was A Desert

Reprint of the 1983 edition.

Describes the author's experiences as a member of a scientific deep-sea drilling expedition to explore the geology of the Mediterranean Sea

The atmosphere is an important pathway for the transport of continentally-derived material to the oceans. In this respect the Mediterranean Sea is of special importance because its atmosphere receives inputs of anthropogenic aerosols from the north and desert- derived Saharan dusts from the south. The dusts, much of which is transported in the form of seasonal `pulses', have important effects on climate, marine chemistry and sedimentation in the Mediterranean Sea. This volume brings together reviews and specific-topic papers on the following aspects of Saharan dust transport to the Mediterranean Sea: (i) the modelling of Saharan dust transport, (ii) the chemistry and mineralogy of the dusts and their effect on precipitation, (iii) the contribution of the dusts to marine sedimentation, (iv) the aerobiology of the dusts, and (v) climatic implications of Saharan dust transport. The volume is aimed at students and researchers with an interest in the climate, biogeochemistry and geology of the Mediterranean Sea.

Based on the suggestions made by the speakers of Plenary Session IV “Ch- lenges to the management of water resources and to countering deserti cation in the Mediterranean region” during the 15th Economic and Environmental Forum, the OCEEA proposed to organize a workshop on “Water Scarcity, Land Degra- tion and Deserti cation in the Mediterranean region – Environment and Security Aspects”. In order to build on common synergies, OSCE sought co-operation with c- leagues from NATO, in particular from the Science for Peace and Security P- gramme. NATO has a longstanding expertise on the issue and had organised in Valencia, in December 2003, a NATO scienti c workshop on “Deserti cation and Security in the Mediterranean Region”. The objective of the new proposed wo- shop would be to broaden its focus from the scienti c community to include also policy makers. 1 The workshop, aimed at government of cials from the Mediterranean Region, gathered representatives of Water management, Land degradation and Desert- cation Departments of Ministries of Environment and representatives from the Ministries of Foreign Affairs. In addition, policy makers, scientists and experts were also invited. The aim was to discuss how the OSCE, NATO and other c- petent organizations like the UNCCD, UNEP, MAP, and the EU could play a role in ensuring that environment and security linkages in terms of water scarcity, land degradation and deserti cation are addressed in the Mediterranean Region.
