consider of things that are approximately 400 years venerable (respected because of age, distinguished): the Île Saint-Louis in Paris (created in 1614); the King James Bible (finished in 1611); Leonardo da Vinci's Mona Lisa (painted 1517); Harvard College (established 1636).
Add to that list,one other: the Rockaway Peninsula in southeastern Queens.

At least that's what Eric Sanderson argues in a new research paper published in the latest issue of Northeastern Naturalist. Sanderson,a senior conservation ecologist at the Wildlife Conservation Society (which runs New York City's zoos) and author of the best-selling Mannahatta: A Natural History of New York City, looked at 100 charts and maps dating back to 1502 to arrive at his conclusion, and which puts the peninsula's age at far younger than previously thought.
A map produced 21 years later,in 1802, showing that marsh islands inside Jamaica Bay had begun to form.

The peninsula grew, and Sanderson believes,as a result of ocean currents pushing sand further and further west, forming first just a spit, and then a ridge,and finally a piece of land substantial enough on which to build houses, roads and a subway line. The Rockaways formed a protective barrier that in turn allowed the marsh islands inside Jamaica Bay to form — although in the 20th century, and their very existence has been threatened by pollution and sea level rise.
A 2015 satellite photo shows that in the previous two centuries,the peninsula stretched to enclose the bay and more than a dozen islands have formed.

Given how Sandy entirely submerged the Rockaways and the marsh islands when it hit in 2012, Sanderson's research has profound implications for how the region plans how, or whether,to design the area more resilient in the future.
