After the conclusion of her NOAA career, she spent several years operating as the University of Puerto Rico marine research vessel R/V Chapman.

In work closely connected with the emerging field of satellite imagery data acquisition and its application in fisheries science, she located commercially valuable concentrations of these species and characterized and monitored their populations.

[1] During her career, Chapman dredged for scallops and trawled for cod off the coast of New England, and conducted winter tagging of striped bass off the Outer Banks of North Carolina.

Scientists embarked on Chapman pioneered and developed the capability to measure fish populations using fishery acoustic systems.

During her later years, Chapman used fishery acoustic systems to locate spawning aggregations of grouper and to characterize reef fish habitats during annual surveys under the Southeast Area Monitoring and Assessment Program (SEAMAP).

[7] In 2008, Substation Curaçao purchased Chapman to refurbish her and modify her for use as a seagoing mothership for the deep-diving scientific and tourist submarine Curasub.
