Passion for the ocean unites us as a team, and drives us to be our best every day. We are determined to reach a massive positive impact for the oceans, the planet, and human societies.
At the core of our initiative lie respect and empathy for nature and all living beings. We strive to create a healthy, caring, and appreciative working environment, open to everyone regardless of gender, beliefs, or ethnicity.
Embracing a ‘no-bullshit’ philosophy, we refuse to make false promises. Honesty and transparency are key to our communication.
We are guided by curiosity, critical thinking, and the pursuit of new challenges, while adhering to scientific standards and high quality of work.
We are supported by a group of brilliant volunteers and students who are taking a lot of work from our shoulders and contributing to rrreefs in many meaningful ways.
