In oligotrophic environments, dust and nutrient inputs via atmospheric routes are considered important sources of macro-nutrients and micro-trace metals fuelling primary and secondary production. Yet, the impact of these dust inputs on the microbial populations is not fully investigated in the Eastern Mediterranean Sea (EMS). The response of oligotrophic systems to dust inputs, whether as positive or negative feedbacks to autotrophic and heterotrophic production and thus to biogeochemical cycling, is important to examine further. Experimental studies have explored nutrient additions in various combinations to determine the limiting resource to productivity or N2 fixation. Recent experimental studies have applied dust enrichments to bottle or mesocosm incubations of seawater from different oceanic regions. This research topic presents two Eastern Mediterranean dust addition mesocosm experiments using, for the first time, real aerosol additions, pure Saharan dust and mixed aerosols (a natural mixture of desert dust and polluted European particles), as well as other EMS aerosol experimental studies. The Topic includes manuscripts introducing results on: a) the impact of Saharan dust vs mixed aerosols on the autotrophic and heterotrophic surface microbial populations in the EMS, b) the impact of single vs multi-pulses of Saharan dust introduction into the pelagic environment of the EMS and c) other experimental studies of aerosol impacts on the EMS ecosystem.

This book is a significant contribution to the field of survey pottery studies, which is not frequently theorised, and could also serve as a guide and provide inspiration to archaeologists designing their own survey projects and methodologies.Landscape archaeology has heavily relied on pedestrian survey as a field method for more than half a century. In most field projects, archaeological ceramics constitute the lion's share among the finds and the amount of collected sherds is overwhelming. Survey ceramics provide the basis for understanding human activity in a landscape, and sherds serve as convenient chronological markers for the archaeological sites discovered in field projects. However, how this pottery is collected and studied determines the possibilities for using the sherds as a source material. Not only the collection practices, but also the process and practicalities of ceramic analysis are rarely made explicit, even though the archaeological interpretations of human activity in the landscape strongly rely on it.Most contributions in this volume provide an insight in collection, processing and interpretation practices in a specific survey project, and we hope this transparency is inspiring and contributes to a better understanding of surface ceramics as a basis for historical interpretations. Three themes run as a red thread through the contributions in this book: first of all transparency in ceramic collecting, processing and interpretation, secondly, improving diagnosticity, and thirdly, expanding the interpretive potential of survey ceramics.The chapters are geographically oriented towards Greece, Italy and Spain, three countries in which archaeological surface survey is widely practised. Chronologically, the contributions range from the Final Neolithic to the Medieval period.
