Metropolitan City of Venice had annexed Padua and Verona, and by the 16th century the republic included territories from the Julian Alps to Crema, Istria, Dalmatia, Cyprus and part of the Peloponnese. In 1797, Napoleon invaded the Republic and, following the Treaty of Campo Formio, it was ceded to Austria. After the final defeat of Napoleon, the Austrian Empire founded a province of Venice on the Adriatic. In 2015 this was converted to the current Metropolitan City. Facing east on the Northern Adriatic Sea, the Metropolitan City is bordered to the northeast by the Province of Udine and Province of Pordenone, south by the
Gulf of Mexico Island. The Gulf contains a hypoxic dead zone that runs by east-west along the Texas-Louisiana coastline. In July 2008, researchers reported that between 1985 and 2008, the area roughly doubled in size and now stretches from near Galveston, Texas, to near Venice, Louisiana. It is now about , nearly the record. Poor agricultural practices in the northern portion of the Gulf of Mexico have led to a tremendous increase of nitrogen and phosphorus in neighboring marine ecosystems, which has resulted in algae blooms and a lack of available oxygen. Occurrences of masculinization and estrogen suppression were observed as a result.
