Subject: Effective immediately, National Data Buoy Center
 Coastal-Marine Automated Network (C-MAN) Station CHLV2
 located on the Chesapeake Light Tower has been

C-MAN station CHLV2 was established by the National Data Buoy
Center (NDBC) in the mid 1980s on the (former) USCG Chesapeake
Light Tower, about 15 miles east of the mouth of the Chesapeake
Bay. In 2012, the tower was deemed structurally unsound and was
condemned by the US Coast Guard. NDBC lost access to the tower
to service and maintain the C-MAN equipment. C-MAN CHLV2
continued to operate, transmitting data until early July 2016.
There are no platforms near the tower to which the C-MAN station
could be moved, therefore CHLV2 has been discontinued and
disestablished effective immediately. NOAA operates several
weather stations and buoys within a few miles of the Chesapeake
Light Tower, including three water level network stations at the
mouth of the Chesapeake Bay and a Chesapeake Bay Interpretive
Buoy just inside Chesapeake Bay.
