AN buoy

A buoy was first deployed at the mouth of the Severn River off Annapolis, Maryland, on November 18, 2009. This buoy has been pulled for several winters to keep it safe from potential ice damage, so overwinter data gaps, as well as other intermittent data gaps, exist. 

"The western shore by which we sailed we found all along well watered, but very mountainous and barren, the valleys very fertile, but extreme thick of small wood so well as trees and much frequented with wolves, bears, deer, and other wild beasts." - Captain John Smith, 1608

Today, Annapolis is a major hub for recreational boating and is home to the U.S. Naval Academy. The natural harbor early settlers enjoyed that is now downtown Annapolis is evident on NOAA charts for the area.

Be sure to check the weather forecast before you head out.
