Don’t be shy. The application is free and a great way to get to know each other. The more you tell us about yourself, the easier it is to help you out. Diving is hard enough, so the application is easy.

Welcome to the Internship application page!


For a non-binding application, please send us a short and non-formal letter of motivation, and a resume/CV in .doc, .docx or pdf format.

Please explain what you think we can do for you, what you can do for us, state your experience in diving and research (if any), and state all other qualifications that you think are useful to us. It’s for getting to know you a little better and speed up the process.

Don’t be intimidated if you don’t have any experience yet, we’re here to help with that!

Please don’t write your motivation in the email content, use the email as a cover letter.

Please note: only complete applications (Letter of Motivation AND CV/resume) will be processed. Your placement can only be guaranteed after you paid an initial deposit of the course fee. We follow a strict first-come-first-serve policy.

Please send your information to & state in the subject whether you are applying for the Marine Conservation Internship or Marine Research Internship program.

We look forward to hearing from!

Marine Conservation Internship costs


CORE sea is a non-profit organisation, which means we are not a normal business, like a dive school or so. Our primary goal is to achieve our mission statement, while covering the costs that arise in the process. Which is a long way of saying: no discounts.

We offer packages from 2-12 weeks for suitable candidates. Read below to find out what’s included.

For costs of the Marine Research Internship program please email us directly at

All prices are in Thai Baht (THB or ฿).

Wait, what?

Science is fun?
