Operational history
November 1999, Carolyn Chouest assisted recovery efforts after the EgyptAir Flight 990 airplane crash 60 mi south of Nantucket, Massachusetts. She provided underwater mapping of the debris field using the side-scan sonar and recorded underwater video of the site with the ROV Magnum.

February 2002, NR-1 and Carolyn Chouest helped archeologists to chart the USS Monitor, the Navy's first ironclad warship, as she rests 250 ft below the sea.

October 2004, Carolyn Chouest helped tow HMCS Chicoutimi (SSK 879) back to Faslane, after a fire on board the Canadian submarine killed one crewman and injured two, 100 mi off Ireland.

December 2006, the fast-attack submarine, USS Pittsburgh (SSN-720) resurfaced during sea trials after a 25-year-old Portsmouth Naval Shipyard employee began having neurological problems. He was safely transferred to Carolyn Chouest and continued to receive treatment from Pittsburgh's corpsman until medevaced by a Coast Guard helicopter.

March 2007, NR-1 and Carolyn Chouest under the direction of oceanographer Robert Ballard began mapping the Flower Garden Banks National Marine Sanctuary to help scientists determine where early Americans might have lived when, at the height of the last ice age, sea levels were nearly 400 ft lower than they are today.
