# Geological Evolution of the Venice Lagoon New research reveals how rising sea levels transformed ancient inland landscapes into today's iconic lagoon. - **Source:** [Environment | The Guardian](https://www.theguardian.com/uk/environment) - **Published:** 2026-10-28 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/223d1642-fda2-471e-a295-34d4b128362f ## Ancient Landscapes Revealed Research led by Samuele Ongaro at the University of Southampton demonstrates that the Venice lagoon was once dry land. By analyzing seismic data and sedimentary cores from Italy, Slovenia, and Croatia, scientists reconstructed the northern Adriatic coastline. This study confirms that the area extended over 30 miles further inland than it does today. ## Methodology of Reconstruction The team utilized a combination of geophysical seismic data and physical sedimentary cores to model historical sea levels. This dual approach allowed researchers to map the transition of the northern Adriatic basin over the last 10,000 years. These findings provide a precise look at how ancient hills and swamps were submerged by rising waters. ## Rapid Sea Level Shifts Starting approximately 10,000 years ago, sea levels rose in inconsistent intervals. Some periods saw increases of up to 25mm per year, drastically altering the topography. These rapid changes forced Mesolithic hunter-gatherer populations to constantly adapt their fishing and hunting strategies as their familiar environment disappeared beneath the encroaching Adriatic Sea waves. ## Three Distinct Phases The transformation of the northern Adriatic occurred in three specific, dramatic phases. These shifts fundamentally reshaped the geography before entering a period of relative stability over the last 6,000 years. This stabilization was critical for the subsequent development of human settlements and the eventual emergence of farming practices in the region. ## Trieste Historical Context The study highlights that the area surrounding Trieste was historically characterized by hills overlooking swamps and lagoons. This stands in stark contrast to the modern coastal profile of the city. Understanding these ancient features helps clarify how the broader Adriatic landscape evolved from a terrestrial environment into the current maritime configuration. ## Human Adaptation Strategies Mesolithic populations faced significant environmental pressure as the coastline retreated. They were required to shift their subsistence activities to keep pace with the rising water levels. This historical adaptation demonstrates the resilience of early human groups living in the northern Adriatic basin during a period of intense and rapid geological change. ## Publication and Scientific Impact The findings were published in Quaternary Science Reviews, offering a comprehensive look at the northern Adriatic's geological history. By mapping the transition from dry land to the present-day lagoon, the research provides a vital baseline for understanding long-term coastal evolution. This work bridges the gap between geological data and human history. ## Geological Stability Significance The transition from volatile sea level rises to a 6,000-year period of stability enabled the formation of the modern Venice landscape. This stability allowed for the establishment of permanent settlements and the growth of agricultural systems. The study underscores how geological conditions dictate the feasibility of long-term human habitation and infrastructure development. ## Sources covering this story - https://www.theguardian.com/science/2026/oct/28/rising-seas-transformed-dry-land-venice-lagoon — --- _Summary written by Brifing from the original reporting.
