Ensign Carson was a Starfleet officer in the late 24th century. In 2372, she was aboard the USS Defiant during a trade arrangement with the Karemma. When the mission started she handed over the result of the last weapons drill to Worf and got orders to bring the response time down by at least fifteen percent. Before the weapons drill was finished she noticed two starships enter Defiant's sensor range and identified them as Jem'Hadar. Carson made it safely back to Deep Space 9, where she resumed her duties. (DS9: "Starship Down")
