The lack of highly-trained ocean science professionals constrains sustainable development and management of the oceans. In Kenya, the government is committed to improving access to education for all, regardless of gender, ethnicity, and social status. Increasing female student enrolment has been one of the top priorities, particularly in science-related courses, which have long been male-biased. Feminist political ecology is applied as an analytical framework to understand how gender and ethnicity influence student access to, participation in, and experience in ocean science-related programmes. Data was collected through a questionnaire survey with students undertaking ocean science courses in seven public universities in Kenya. The findings revealed an underrepresentation of women and minority ethnic groups. Fewer female respondents than males received financial support from their families, and more female respondents than males reported that they had experienced discrimination related to their ethnicity and gender. In addition, a higher percentage of female respondents reported having fewer opportunities in higher education and ocean science careers than males. These findings reveal the persistent inequalities among students and suggest that Kenyan public universities need to pay more attention to how intersectional identities, such as gender and ethnicity, influence and shape the distribution of resources and opportunities if equitable diversity and inclusion are to be achieved. Also, they need to strengthen their gender policies and actions to tackle these social inequalities to promote gender equality in ocean science education.
