From Ancient Deforestation, a Delta Is Born

Humans were tampering with nature long before the Industrial Revolution’s steam and internal combustion engines arrived on the scene. The invention of agriculture around 8,000 years ago, some argue, significantly changed ecosystems as it spread around the globe.<br /><br /> Although scientists are only just beginning to understand how these ancient alterations shaped our world today, a new study in Scientific Reports suggests that millennium-old development along the Danube River in Eastern Europe significantly changed the Black Sea ecosystem and helped create the lush Danube Delta in Romania and Ukraine.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhd2kb2o_fRiob1eQplW8ocpingiketuxjZgO6ovIMEt0yO-W59J0pHHoW69wjROeEZZTGFce0adc7Srs4sPjpqIUfdTIIp7HSo7CSwOvSoA4Bby45XHusjVdChjucQfmSa_B54YluwPPE/s1600/Danubemap.jpeg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="287" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhd2kb2o_fRiob1eQplW8ocpingiketuxjZgO6ovIMEt0yO-W59J0pHHoW69wjROeEZZTGFce0adc7Srs4sPjpqIUfdTIIp7HSo7CSwOvSoA4Bby45XHusjVdChjucQfmSa_B54YluwPPE/s400/Danubemap.jpeg" width="400" /></a></div><br /><br /> “My team had a big surprise,” said Liviu Giosan, a geologist at the Woods Hole Oceanographic Institution in Massachusetts and the lead author of the study. “We found that around a thousand years ago, the entire basin changed dramatically, though that later made sense when we put it into context.”<br /><br /><b><a href="http://green.blogs.nytimes.com/2012/09/14/from-ancient-deforestation-a-delta-is-born/" target="_blank">Click here to read this article from the New York Times</a></b><br /><br />See also: <b><a href="http://www.nature.com/srep/2012/120830/srep00582/full/srep00582.html" target="_blank">Early Anthropogenic Transformation of the Danube-Black Sea System</a></b>

Elizabethan Map of America provides clue to ‘Lost Colony’

<br />After decades of unsuccessful searching, archaeologists may have their best evidence ever of the possible fate of Sir Walter Raleigh’s “Lost Colony.” It comes in the form of a clue from Sir Walter himself, secreted within the 425 year old “Virginea Pars” map drawn by his expedition to site the first English colony in the New World.<br /><br />At a conference held yesterday at the University of North Carolina at Chapel Hill, archaeologists and scholars from the First Colony Foundation and the British Museum discussed the newly discovered information previously hidden within the map and possible implications for understanding the eventual fate of Raleigh’s “lost colonists.”<br /><br />The “Virginea Pars” map was produced from explorations conducted by members of Sir Walter Raleigh’s Roanoke Colony of 1584-1590. The remarkably-accurate map depicts the coastal area from Chesapeake Bay to Cape Lookout, including the location of many native American villages visited by the colonists. However, until now the map provided little information about the location of his planned “Cittie of Ralegh.”<br /><br /><b><a href="http://earlymodernengland.com/2012/05/elizabethan-map-of-america-provides-clue-to-lost-colony/" target="_blank">Click here to read this article from Early Modern England</a></b><br />

Warning signs from ancient Greek tsunami

In the winter of 479 B.C., a tsunami was the savior of Potidaea, drowning hundreds of Persian invaders as they lay siege to the ancient Greek village. New geological evidence suggests that the region may still be vulnerable to tsunami events, according to Klaus Reicherter of Aachen University in Germany and his colleagues.<br /><br />The Greek historian Herodotus described the strange retreat of the tide and massive waves at Potidaea, making his account the first description of a historical tsunami. Reicherter and colleagues have added to the story by sampling sediments on the Possidi peninsula in northern Greece where Potidaea (and its modern counterpart, Nea Potidea) is located. The sediment cores show signs of “high-energy” marine events like significant waves, and excavations in the suburbs of the nearby ancient city of Mende have uncovered a high-energy level dated to the 5th century B.C. The Mende layer contains much older marine seashells that were probably scoured from the ocean bed and deposited during a tsunami.<br /><br /><b><a href="http://historyoftheancientworld.com/2012/04/warning-signs-from-ancient-greek-tsunami/" target="_blank">Click here to read this article from History of the Ancient World</a></b>
