A Coast Guard crew has uncovered several potential navigation hazards during the agency's first patrol of Sandy Hook waterways since Superstorm Sandy hit the region a week ago.

The small-boat crew off the Coast Guard Cutter Ridley, which is homeported in Montauk, N.Y., conducted its mission Saturday.

While performing the law enforcement patrol, crew members observed various hazards in the Sandy Hook Bay and inlet, including a sunken vessel, floating debris and displaced aids to navigation buoys. Coast Guard officials urged boaters to be aware of these and other potential hazards while traveling in Sandy Hook's waterways.

The Ridley is one of many Coast Guard cutters that were deployed to the New York and New Jersey waters to assist in harbor assessments, recovery efforts and law enforcement.
