CAS: Marine Science

Sample Pathway

Below is an example of a four-year plan of a College of General Studies student pursuing a degree in marine science. Students will work with their CGS academic advisors and the marine science department to plan their own pathway to a marine science degree.

Gap Semester Recommended external course: Calculus I (equivalent to CAS MA 123) or Calculus for the Life and Social Sciences I (equivalent to CAS MA 121). Note: Prior approval must be granted for external coursework.
  Semester I Semester II
Freshman Year CGS RH 103
CGS SS 103
CAS MA 115 or CAS MA 213
CAS CH 101
CGS Required Courses (London or Boston-New England semester)
Sophomore Year CGS HU 201
CGS NS 201
CAS EE 144 (lecture and discussion) 
CAS CH 102
CGS HU 202
CGS SS 202
CAS BI 108
Second Language (if needed)
Junior Year CAS PY 211 or CAS PY 105
Math or computer science course
Elective*
Second Langage (if needed)
CAS BI 260
Marine breadth course
Elective*
Second Language (if needed)
Senior Year Marine semester (4 marine courses) Marine breadth course
Marine breadth course
Elective*
Second Language (if needed)

*Choose your electives carefully to fulfill any remaining BU Hub requirements. You will find a list of all of the courses that carry Hub units on the University’s BU Hub website. External courses are not eligible for Hub general education credit.

College of General Studies Program Requirements

  • Two rhetoric courses: CGS RH 103 and CGS RH 104
    • CGS RH 104 is taken during the London semester
  • Two natural science courses: CGS NS 201 and CGS NS 202
    • CGS NS 201 fulfills the CAS BI 107 requirement. Marine science majors in good standing will take CAS BI 108 in place of CGS NS 202. 
  • Three social science courses:
    • CGS SS 104 is required and is taken during the London semester
    • Students select at least two additional SS courses and will work with their academic advisor to determine course selection
  • Three humanities courses:
    • CGS HU 104 is required and is taken during the London semester
    • Students select at least two additional HU courses and will work with their academic advisor to determine course selection

Note: Students who are exempt from CGS NS 202 must enroll in at least one CGS course in semester II of sophomore year.

Major Requirements

The major in marine science is 17 courses. The major requires eight related courses in chemistry, biology, physics, calculus, and statistics. All students take Introductory Oceanography (CAS EE 144), Marine Biology (CAS BI 260), three “marine breadth” courses, and the marine semester. All courses for the major must be completed with a grade of ‘C’ or higher. For required courses, please see the CAS Bulletin.

One semester of Calculus 1, one semester of Statistics 1, and one semester of either Calculus 2, Statistics 2, or Computer Science is required. Students must take:

CAS CH 109 and CAS CH 110, or CAS CH 111 and CAS CH 112, or CAS CH 171 and either CAS CH 172 or CAS CH 174 may be taken in place of CAS CH 101 and CAS CH 102. The CAS CH 101/102 sequence is recommended for marine science majors.

The marine science major requires participation in at least one marine semester. For more information, please see: Marine Science Department webpage.

Note: A marine breadth course should be taken during sophomore year to participate in the marine semester in semester I of junior year. At least one marine breadth course must be completed prior to the marine semester. Please consult with Julia Hammer Mendez in the marine science department for course planning and advice.

Pre-Medical Students

Pre-Medical students are strongly advised to take CAS BI 108. Pre-medical students are required to take CAS CH 101, CAS CH 102, CAS CH 203, and CAS CH 204. One year of physics (with laboratory) is required. Courses in biochemistry, psychology, and sociology are required for the new MCAT exam. Students planning to attend medical school should consult with advisors in the marine science department and in the pre-medical advising office (100 Bay State Road, Room 428) for information on the selection and sequencing of courses.

Continuation Requirements

  • Completion of the CGS required courses and appropriate electives
  • Cumulative GPA greater than or equal to 2.00

Graduation Requirements

Boston University students completing a degree in CAS must also complete the following requirements. 

  • BU Hub requirements
    • Students who take the specific CGS courses noted on the pathway above will fulfill all BU Hub requirements except the units listed below. These remaining Hub units will be fulfilled through the following courses:
    • Quantitative Reasoning II (1 unit) fulfilled by CAS BI 108
    • Teamwork/Collaboration (1 unit) fulfilled by CAS BI 108
    • You will fulfill the remaining Hub units – Creativity/Innovation (1 unit), Global Citizenship and Intercultural Literacy (1 unit), Teamwork/Collaboration (1 unit), and Writing-Intensive Course (1 unit) – through the courses you take for your CAS major and/or other electives
  • CAS requirements:
  • Marine Science major requirements
  • CAS requires a minimum of 128 credits, excluding PDP, ROTC, and CAS FY and SY courses.

This is a sample pathway to be used in consultation with your CGS Academic Advisor.

It is subject to change according to course availability and individual circumstances.
