The Blue Economy extends far beyond marine biology and oceanography. Understanding our coasts, geological history, and the processes that shape marine environments is essential for protecting coastal ecosystems, preserving natural heritage, and preparing for future environmental challenges. Geologists play a key role in helping us understand both the past and the future of our oceans.
In this edition of our interview series, we’re speaking with Rúben M. Santos, a geologist based in Portugal who combines laboratory work, coastal field surveys, paleontology, and science communication. As a freelancer and volunteer at the Sociedade de História Natural de Torres Vedras, Rúben works at the intersection of geology, coastal processes, and public engagement, helping people better understand the dynamic relationship between the land and the sea.
Meet Rúben M. Santos
Current Role: Freelance Geologist, Laboratory Technician & Science Communicator
Industry: Geology, Coastal Science, Paleontology, Science Communication
Focus Areas: Coastal processes, coastal geomorphology, paleontology, geological fieldwork, environmental education
Organization: Sociedade de História Natural de Torres Vedras
The Sociedade de História Natural de Torres Vedras is a Portuguese non-profit organisation dedicated to geological and paleontological research, natural heritage conservation, and science communication. Through his work there, Rúben contributes to research, laboratory activities, educational programmes, and public outreach.
What inspired you to pursue this path?
Rúben’s interest in the Blue Economy grew from his fascination with the connection between geology and the ocean.
During his geology degree at the Faculty of Sciences of the University of Lisbon, he became particularly interested in subjects such as Coastal Processes and Coastal Morphodynamics.
«As a scientist I was completely fascinated by the point where oceanography, geography and geology meet.»
Understanding how waves, sediments, and coastlines interact became a constant source of inspiration.
«The interaction of the ocean with the coast and all its dynamism are a source of inspiration.»
A Day in the Life
Rúben’s work combines laboratory analysis, field surveys, and public outreach.
In the laboratory, he prepares and cleans fossil material, removes sediment from specimens, and catalogues geological collections.
Fieldwork often involves exploring beaches and coastal cliffs in search of fossil-bearing rocks. When significant material is discovered, it must be carefully extracted for further study by the research team.
Alongside his scientific work, Rúben regularly participates in science communication activities, delivering talks, workshops, and guided tours for schools and the general public.
His work allows him to move between laboratory analysis, coastal fieldwork, and education, making every week different depending on research priorities, discoveries, and outreach activities.
The Exciting and Challenging Aspects of the Job
Fieldwork is one of the aspects Rúben enjoys most about his profession.
«It can be finding a fossil, seeing a beach completely change its profile as sand migrates along the shore, or observing swash zones produced by waves from the clifftops.»
One of the highlights of his career so far has been the recent discovery of a dinosaur footprint with unique characteristics that is currently being studied by paleontologists.
He explains that every day in the field offers an opportunity to discover something new, whether it is a fossil, an evolving coastal landscape, or evidence of geological processes in action.
Working in the non-profit sector, however, also presents challenges.
«Working with NGOs usually means lower income, and this is currently my case.»
He also points out that much of his work takes place away from the coast. Administration, reporting, logistics, funding applications, and coordinating projects require a significant amount of time, while bureaucracy and limited resources can often slow down the implementation of good ideas.
«However, this is also what makes the job interesting, because it forces you to be flexible and creative.»
Key Skills for Success
Rúben believes that success in his field requires both scientific knowledge and resilience.
Technical Skills:
- Geology
- Coastal geomorphology
- Paleontology
- Laboratory techniques
- Field surveying
Soft Skills:
- Adaptability
- Resilience
- Attention to detail
- Communication
- Ability to work under challenging weather conditions
He also highlights that fieldwork often requires working carefully despite difficult environmental conditions.
«Besides the technical knowledge, it’s important to apply it under whichever meteorological conditions are present. Working meticulously under heat, while keeping your concentration, is an important skill.»
Work-Life Balance & Career Satisfaction
Rúben is very satisfied with his work-life balance, which allows him enough time to enjoy life outside work.
However, he believes that salaries within the NGO sector often do not reflect the level of knowledge, experience, and effort required for scientific roles.
Future Outlook: Where is the Industry Heading?
Looking ahead, Rúben hopes to specialise in natural hazards and geological risk assessment.
«I would like to evolve into a role regarding hazards and risks, especially tsunami effects, using my geological insight to study past events and help mitigate future ones.»
As coastal communities face increasing environmental pressures, geological knowledge will continue to play an important role in understanding coastal evolution, natural hazards, and long-term resilience.
Career Advice for Aspiring Professionals
If he could give one piece of advice to his younger self, Rúben would encourage him to take opportunities without waiting for the perfect moment.
«Don’t expect a perfect moment to launch yourself into a new opportunity.»
His advice reflects the importance of taking initiative, gaining experience, and embracing new challenges whenever they arise.
