"The Seneca Lake sonar test facility, a small U.S. Navy installation on the west shore, is a part of the Naval Undersea Warfare Center Division (NUWC) Newport, Rhode Island. The facility was a marina until about 1962 when the Navy tests began.
Why Seneca Lake? There are many reasons.
First, “Seneca has the isothermic characteristics [constant temperature] that make it an ideal acoustic environment to test sonar,” explains Frank McNeilly, NUWC Newport’s waterfront operations manager. Its maximum depth of 618 feet also plays a role. “Higher pressure at deeper levels closely simulates an ocean environment,” he adds.
In addition, the lake is an ideal quiet environment; quieter than the open ocean so it allows for more accurate testing. It also simulates a more realistic environment for submarines, and is less costly than testing at sea, “especially in winter when the water temp is uniform top to bottom,” McNeilly explains. In more scientific terms, Seneca Lake is the Navy’s primary active instrumented calibration and test facility."
interesting i guess.
