After shakedown off Bermuda, MARTS departed New York 4 November for convoy escort duty off the Atlantic coast of South America. She reached Trinidad, British West Indies 9 November, and during the next 5 months operated in the 4th Fleet escorting ships between Trinidad and Recife, Brazil. As escort for light cruiser OMAHA (CL-4), she departed Bahia, Brazil, 23 May 1944 and patrolled the mid-Atlantic, south of the Equator, in search of German U-boats, until returning to Bahia, 5 June.

She made two more patrols during the next month; and, after escorting OMAHA to Gibraltar 13 July, she returned to Recife the 23d. Between 24 July and 3 August, MARTS screened the British cable repair ship SS CAMBRIA during repairs on communications cables off the Brazilian coast.
