The current detailed chronostratigraphic framework of the last 1Ma of an eastern Mediterranean sequence (Haifa Bay, Israel) aims to examine the relative roles of sea-level changes, climate and tectonics. Seven continuous marine cores, up to ~120m long, were recovered from shallow water depths. The cores were dated by optically stimulated luminescence, 14C, magnetostratigraphy, 230Th/ 234U, 26Al/ 10Be, occurrence of index fossils and correlated to the global sea-level curve and Marine Isotope Stages (MIS). The sedimentary sequence accumulated during the last ca. 1.0Ma consists of 21 transgression-regression units with hiatuses between them. Five marine/terrestrial cycles, which occur in the lower part of the sequence, are attributed to the Jaramillo subchron and the Brunhes-Matuyama boundary, and correspond to MIS 29-21. The top ~50m includes three sedimentary cycles deposited in the last ca. 400ka. The regressive phases during this interval correspond to Glacial MIS 8, 6 and 2, while the transgressions correspond to Interglacial MIS 11, 7, 5 and 1. Thus, for the first time, this study documents the longest Quaternary succession dated so far in a key area of the Levant, sensitive to global history of sea-level changes and glacial/interglacial fluctuations.
