Chesapeake Light
Chesapeake Light is an offshore lighthouse marking the entrance to the Chesapeake Bay. Once considered for decommissioning, it remains active and supports atmospheric measurement sites for NASA and NOAA.
==History==
This station was first established in 1930 using a lightship, since lighthouse construction technology at the time was not adequate to the task of supporting a light in such waters. It remained on station (except during World War II) until it was replaced by the present light, built in 1965 as one of six nearly identical "Texas Tower" lights on the East Coast. The United States lightship Chesapeake (LV-116), which formerly was used at the site, is now on display at the Inner Harbor in Baltimore, MD.
The light was automated in 1980, and in 1997, it became a site for NASA to perform meteorological research (see below). In 2001, NASA sponsored a field mission at the lighthouse called the (Chesapeake Lighthouse and Aircraft Measurements for Satellites ) (CLAMS). The CLAMS field mission involved six aircraft flying over the lighthouse to improve understanding of atmospheric aerosols, to validate and improve the satellite data products, and to test new instruments and measurement concepts.
Chesapeake Light was used in 2002-2003 by University of Maryland, Baltimore County students for research projects. The following year it was inspected by the Coast Guard with an eye toward dismantling it, as had happened earlier to the Ambrose and Savannah lights, both of which had been struck by ships. The inspection showed the light to be sound, and the light remains in active service. Chesapeake Light is now the only Texas Tower still in use as an active navigational aid. There are two other nearly identical towers now in private hands: Diamond Shoal Light and Frying Pan Shoals Light.
