Marine Science Technicians, or MSTs, are specialists in Marine Safety, Marine Security, and Environmental Protection. They respond to and investigate marine oil and chemical spills and provide oversight during the cleanup of these spills. MSTs also conduct safety and security inspections of waterfront facilities such as cargo terminals, refineries, and passenger terminals, to prevent accidental and intentional disruptions in the maritime community. They examine commercial ships to ensure compliance with international and federal regulations covering vessel safety, operations, invasive species, and manning. During and after disasters, MSTs can be deployed to utilize specialized training in incident command for response and recovery.

History
Around 1962, Coast Guard enlisted members began being assigned to carry out routine oceanographic observations on ocean stations, ice breakers, and oceanographic ships. These billets were filled by Aerographers Mates (AG) and Sonarmen (SO) until in November 1968, when the decision was made to create a new rating. The new rating absorbed the AG rating and functions and SOs were given the option of converting. The rating supported the Coast Guard's Ocean Weather Station Programs, Aviation Support Programs, International Ice Patrol, and Polar Ice Operations Program, among others. The official name of Marine Science Technician was adopted in 1970.
Training and qualification
Prospective MSTs must meet Armed Services Vocational Aptitude Battery (ASVAB) score requirements of 114 in Verbal Ability plus Arithmetic Reasoning (VE+AR), and a minimum Mathematics Knowledge (MK) score of 56. Training for the rating is accomplished through a 10.5-weeks course at USCG Training Center Yorktown, VA. Upon graduation, MSTs may go on to pursue qualifications such as Pollution Responder, Federal On-Scene Coordinator's Representative, Facility Inspector, Container Inspector, Port State Control Examiner, Port State Control Officer (with vessel type classification) and other specialized qualifications.
