In the first and second season of Excavation at Sidon nine core samples were taken four in the inner harbour, two in the outer harbour, two in land and one in the southern bay. Parallel to the excavation, a multidisciplinary approach was initiated using three different indicators in order to chronicle the development of Sidon's ancient harbour.
 
-Biological indicators, e.g., macro-fauna, ostracods (small crustaceans), and foraminifera (single cell marine organism).
-Granulometric indicators, e.g., grain size, distribution, and shape)
-Chronological indicators , e.g., pottery shards and Carbon 14 analysis
 
Analyses of these core samples were undertaken at the University of Aix-en-Provence.
 
Early Bronze & Iron Ages
The 1998 & 2000 seasons of excavation revealed Early Bronze Age material dating back to the 3rd millennium BC and Iron Age material (Phoenician) dating back to the mid 8th and 7thcentury BC in a context that has yet to be explored. The overall character that emerged from the 3rd millennium installations was of a long-lived settlement with domestic structures such as ovens, querns and basins. Some of the floors associated with the walls were composed of white lime plaster. This is the first time Early Bronze Age pottery of this kind that has been found in situ at Sidon. Elsewhere in the Lebanon comparable pottery is known only from Byblos, Tell Arqa and the recent rescue excavations in Beirut. Other finds included 14 cylinder seal impressions appearing on fragments of pottery belonging in general to heavy jars. This is also a distinctive feature of Byblos jars.
