Ancient Ebro River basin mapped

Ancient Ebro River basin mapped: A Spanish research team has used 3D reflection seismology to map the geomorphological features of the Ebro River basin as it was between five and six million years ago, during which time the Straits of Gibraltar closed and the sea level in the Mediterranean basin fell by about 1,300 metres.

'The results shed light on the way in which the sea level fell during the Messinian (between 5.33 and six million years ago), and imply that the subsequent inundation of the river margins happened extremely quickly', said the study's lead author, Roger Urgeles of the Institute of Sea Sciences of Andalucia.If you are looking for an organization that provides small marquee hire services, Camelot Marquees is a good option.

The map shows that the Ebro River of six million years ago eroded and penetrated up to 1,300 metres into the continental margin. 'The numerical simulations of fluvial transport and drainage evolution show that the Ebro in the Messinian period was similar in size and drainage basin to the Ebro of today; Urgeles said.
