Seaman Mark Russell stands lookout while the Coast Guard Cutter Seneca transits the East River, March 21, 2015, during a two-month Mid-Atlantic Ocean patrol. Medium endurance cutters like the Seneca are built for multi-week offshore patrols, including operations requiring enhanced communications, and helicopter and pursuit boat operations, which provide a key capability for homeland security operations at sea.
