Geoarchaeological cores were retrieved in the centre of the old “Bahia-Caleta” palaeochannel located between the Erytheia and Cotinusa islands in the former Cadiz archipelago, in present-day southern Spain. The unprecedented coring depth (~ 35–50 m) allowed us to identify the bottom of a Phoenician–Punic and Roman harbour. Located at 20–40 m b.s.l. in the sedimentary sequence, silty sand deposits reveal a deep semi-protected shelter with abundant ceramic and archaeobotanical findings. Based on these new results, the palaeotopography of the islands of Cadiz is reinterpreted, demonstrating the presence of a harbour accessible from the west and possibly from the east until (at least) the Roman period. This major discovery opens meaningful perspectives for archaeological, geomorphological and palaeoenvironmental research.

比预期更深：在 Gadir/Gades 发现了一个非凡的古代港口和一个特殊的沉积档案（西班牙南部加的斯）

在位于今西班牙南部的前加的斯群岛的 Erytheia 和 Cotinusa 群岛之间的旧“Bahia-Caleta”古河道中心发现了地质考古岩心。前所未有的取芯深度（~ 35-50 m）使我们能够确定腓尼基-布匿和罗马港口的底部。位于沉积序列中 20-40 m bsl 处的粉砂质砂沉积物揭示了一个深半保护的庇护所，具有丰富的陶瓷和古植物发现。根据这些新结果，加的斯群岛的古地形得到了重新解释，表明存在一个可以从西部和可能从东部进入的港口，直到（至少）罗马时期。这一重大发现为考古学、地貌学和古环境研究开辟了有意义的前景。
