Expeditions
Approaching Monitor on the first submersible dive in 1977, an archaeologist spotted a brass navigation lantern near the turret. Its red Fresnel lens suggested it was a signal lantern. In his account of watching Monitor sink from Rhode Island, Paymaster William Keeler mentioned that at approximately 1:30 a.m., the red distress lantern burning atop the turret and the ship itself was no longer visible.
This lantern was the last visible sign of Monitor before it sank, and more than a century later in 1977, it became the very first artifact recovered from the wreck. The lantern is currently on display in the USS Monitor Center at The Mariners' Museum and Park in Newport News, Virginia.
In 1987, NOAA completed baseline studies at the site that were essential for determining the rate of deterioration of the hull and changes in the sanctuary environment. In the 1990s, NOAA began noticing an alarming pattern of accelerated deterioration in several areas of the wreck. Due to this alarming rate of decay, NOAA was given a mandate in 1996 by Congress to develop a plan to preserve Monitor. In 1998, NOAA released a long-range plan that outlined a six-step proposal for stabilizing portions of the Monitor's hull and recovering the vessel's steam engine and rotating gun turret.
