<p>[QUOTE=&quot;Kentucky, post: 2556088, member: 33176&quot;]About the salinity and current flow...this is from Wikipedia...Today, evaporation of surface seawater (output) is more than the supply (input) of fresh water by precipitation and coastal drainage systems, causing the salinity of the Mediterranean to be much higher than that of the Atlantic—so much so that the saltier Mediterranean waters sink below the waters incoming from the Atlantic, causing a two-layer flow across the <a href="https://en.wikipedia.org/wiki/Strait_of_Gibraltar" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/Strait_of_Gibraltar" rel="nofollow">Gibraltar strait</a>: that is, an outflow <a href="https://en.wikipedia.org/wiki/Strait_of_Gibraltar#Inflow_and_outflow" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/Strait_of_Gibraltar#Inflow_and_outflow" rel="nofollow"><i>submarine current</i></a> of warm saline Mediterranean water, counterbalanced by an inflow <i>surface current</i> of less saline cold oceanic water from the Atlantic.

The underlying energy grid was as well intended to support a political union between Europe and, at least, the Marghreb part of Africa (compare <a href="https://en.wikipedia.org/wiki/Eurafrique" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/Eurafrique" rel="nofollow">Eurafrika</a> for the later impact and <a href="https://en.wikipedia.org/wiki/Desertec" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/Desertec" rel="nofollow">Desertec</a> for a later project with some parallels in the planned grid).<a href="https://en.wikipedia.org/wiki/Mediterranean_Sea#cite_note-54" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://en.wikipedia.org/wiki/Mediterranean_Sea#cite_note-54" rel="nofollow">[53]</a>[/QUOTE]</p><p><br /></p>
