Ghost Shorelines Sonar Maps That Rewrote Prehistoric Trade Routes | Sea Realities

Описание: 🌍 Ghost Shorelines — sonar maps reveal lost coastlines and rewrote how archaeologists trace prehistoric trade routes across the sea. 🌊🛰️🗺️

This investigation shows how multibeam, side-scan and sub-bottom mapping expose “ghost shorelines” — buried coastlines, river mouths and paleo-harbors — and how those features change where we think people landed, traded and moved goods. We follow three case studies (e.g., Doggerland-style reconstructions, Black Sea paleoshorelines, and a regional shelf survey) to show the mapping → coring → archaeological find workflow: sonar reveals the target, sub-bottom data proves buried channels, cores date the deposits, and artifacts or palaeoenvironmental proxies reconstruct human use. Watch multibeam reveals, GIS reconstructions of prehistoric routes, targeted coring, lab radiocarbon results and interviews with mapping scientists about how trade models change when the coastline moves.
