What Does a Marine Biologist Do?
Marine biology is the study of marine organisms, marine ecosystems and the relationships between living organisms and their physical environment. It is one of the broadest disciplines in natural science, spanning everything from microscopic plankton to the largest animals on Earth.
For Rowan Byrne, marine biology has never been confined to laboratory work. His career has combined field observation, scientific research, environmental assessment, conservation, consultancy, photography and public communication.
Rowan Byrne's Marine Biology Career
Rowan's career in marine biology spans more than three decades, beginning with a BSc (Hons) in Marine & Freshwater Biology and developing through postgraduate study, field research, environmental consultancy and senior technical roles.
His academic foundation includes an MSc in Managing the Environment (Distinction) and an MSc in Energy (Distinction) — qualifications that reflect the breadth of his professional work across marine science, environmental assessment and sustainability.
He holds Chartered Scientist (CSci) status and is a Fellow of the Royal Society of Biology (FRSB). He has been recognised by IEMA as a Sustainability Leader and has delivered a TEDx talk on plastic pollution, oceans and civilisation.
Marine Biology Fieldwork
Practical fieldwork has been central to Rowan's career. His field experience spans marine ecological surveys, marine wildlife observation, marine mammal monitoring, habitat assessment, coastal and intertidal environments, biodiversity surveys and offshore environments.
This fieldwork has taken him across more than 22 countries, documenting hundreds of species through direct observation, ecological survey, conservation work and marine photography.
Marine biology in the field: observing, documenting and understanding marine life in its natural environment.
Marine Species & Wildlife Experience
Rowan's documented species experience spans a wide range of marine and freshwater organisms encountered through professional research, field surveys, conservation work, wildlife observation and photography.
His professional research has included deep-sea organisms as part of the Changing Oceans programme, cold-water corals and shellfish in the context of ocean acidification research. His conservation work has involved leatherback sea turtles in Dominica and the Caribbean. His field and survey experience includes marine mammals — whales, dolphins and seals — encountered in the context of ecological assessment and monitoring.
His wildlife observation and photography extends to sharks, rays, dugongs, fish, corals, marine invertebrates and a wide range of marine and freshwater species across tropical, temperate and polar environments.
Rowan distinguishes between professional research, field survey experience, conservation work and wildlife observation. Not every species listed was the subject of formal research.
Marine Conservation & Field Experience
Conservation has been a consistent thread through Rowan's marine biology career. His conservation experience includes sea turtle conservation, leatherback turtles, sharks, marine wildlife, tropical marine environments, habitat conservation, marine pollution and biodiversity.
His work in Dominica and the wider Caribbean involved direct engagement with leatherback sea turtle conservation, including work with the Rosalie Sea Turtle Initiative. This experience is documented across MarineCreatures.com, including in the account of his time in Dominica during the filming of Pirates of the Caribbean.
The Howth Harbour Seabin Initiative is a more recent example of Rowan translating marine biology knowledge into practical conservation action at a community level.
Deep-Sea Marine Biology Research
In 2012, Rowan participated in the Changing Oceans research expedition aboard the RRS James Cook. Independent reporting records him as a marine biologist and Heriot-Watt University researcher investigating the potential impacts of carbon capture and storage leakage on marine ecosystems.
His research involved investigating potential effects of CO₂ on marine species, including cold-water coral and shellfish — organisms that are particularly sensitive to changes in ocean chemistry.
This work sits at the intersection of deep-sea ecology, climate science and ocean acidification — areas of growing importance as the effects of climate change on marine ecosystems become better understood.
Marine Plastics & Pollution
Marine biology increasingly involves understanding the effects of human activity on marine environments. Plastic pollution is one of the most significant and pervasive pressures on marine ecosystems, affecting species from plankton to whales.
Rowan's professional work in marine plastics developed during his time at Mott MacDonald, where he held the role of Marine Plastics Lead. His work covered marine litter assessment, plastic pollution research, microplastics, wastewater and riverine pathways, plastic capture technologies, marine monitoring and practical pollution-reduction projects.
Howth Harbour Seabin Initiative
Rowan saw plastic accumulating in Howth Harbour, County Dublin, and initiated the installation of a Seabin — a practical, community-focused project designed to intercept plastic pollution before it reaches the wider marine environment.
The initiative involved crowdfunding, employer support, community involvement and cooperation with the harbour authority. TheJournal.ie independently describes Rowan as the marine biologist who started the initiative.
The project attracted national media coverage across TheJournal.ie, the Irish Independent and RTÉ Radio 1, and is a documented example of a marine biologist driving practical environmental action at a community level.
Marine Biology Through Photography
Photography has been part of Rowan's marine biology work for decades. With thousands of original photographs spanning marine wildlife, underwater environments, conservation fieldwork, expeditions and natural history, the photographic archive on MarineCreatures.com is a visual record of marine life and the environments in which it lives.
Photography is not simply a record of places visited. It documents species, habitats, behaviours, field locations and conservation stories — contributing to the observational record that underpins marine biology.
From Marine Biology to Environmental Consultancy
Rowan's career developed from marine biology and field research into senior environmental consultancy and technical leadership. His professional experience includes roles at Mott MacDonald, Ocean Science Consulting and WSP.
During his time at Mott MacDonald, he held senior roles in marine ecology and environmental assessment, including the Marine Plastics Lead position. At Ocean Science Consulting, his work focused on marine ecological assessment and environmental science. At WSP, he has worked as a Technical Director in marine ecology.
This career trajectory illustrates how marine biology can develop into a wide range of professional applications — from environmental impact assessment and offshore renewable energy to marine licensing, biodiversity, marine mammal mitigation and sustainability.
Marine Biology as a Career
Marine biology is a broad discipline that can lead in many directions. The routes available to a marine biologist depend on their interests, postgraduate study, field experience and the sectors in which they choose to work.
Rowan's career illustrates one trajectory: from undergraduate marine biology through postgraduate environmental and energy studies, into field research, conservation, environmental consultancy and technical leadership across marine ecology, marine plastics and offshore energy.
Rowan's career is one example of how marine biology can develop. There are many routes into and through the discipline.
