Core Responsibilities

Primary Functions

Plan and conduct systematic field surveys and sampling of marine environments—including reefs, estuaries, open ocean, intertidal zones and deep sea—collecting biological, chemical and physical data on marine life and habitats.
Collect, process and preserve marine specimens (flora, fauna, microorganisms, sediments, water) for laboratory analysis or reference collections, ensuring accurate documentation, labeling and chain‐of‐custody.
Design and execute laboratory experiments to study marine organism physiology, behaviour, genetics, species interactions, pollutants and ecosystem responses under controlled and field‐based conditions.
Monitor and evaluate the health of marine ecosystems, including species population assessments, biodiversity inventories, pollution impacts, invasive species detection and habitat condition monitoring.
Analyse complex datasets using statistical software and spatial modelling tools (e.g., GIS, remote sensing) to interpret marine ecological trends, map species distributions, predict ecosystem changes and support conservation planning.
Develop, implement and manage long‑term marine monitoring or research programmes—defining objectives, sampling protocols, quality control procedures and data management systems.
Conduct environmental impact assessments (EIAs) and risk analyses for marine developments, offshore infrastructure, aquaculture or conservation projects, and provide scientifically grounded recommendations to stakeholders and regulators.
Maintain, calibrate and operate marine and laboratory equipment (e.g., sampling gear, sondes, CTD probes, microscopes, imaging systems), manage inventories and ensure data integrity and operational readiness.
Supervise field expeditions and lab work—leading dive teams, coordinating boat or vessel work, training junior staff, interns or volunteers, ensuring safety, logistics and scientific rigour.
Prepare technical and scientific reports, peer‐reviewed publications, conference presentations, outreach materials or policy briefs to communicate marine biology findings to academic, industry and public audiences.
Collaborate with multidisciplinary teams and external stakeholders—research institutions, NGOs, governmental agencies, marine industries, indigenous communities or fisheries—to integrate marine biology insights into conservation, management or commercial frameworks.
Stay current with emerging marine science, technology and regulatory frameworks; evaluate and adopt new methods (e.g., genetic barcoding, eDNA, remote monitoring) to maintain best‑practice marine biology research.
Develop grant proposals, manage project budgets, contracts and deliverables, coordinate funding applications and contribute to business development or marine programme expansion.
Maintain safety, ethical and environmental compliance in marine research and fieldwork—ensuring adherence to diving regulations, wildlife handling, permitting, biosecurity, environmental protection and occupational health standards.
Engage in habitat restoration or species recovery projects—design, monitor and evaluate interventions in marine ecosystems, such as reef rehabilitation, mangrove planting, or fish stock enhancement.
Conduct stakeholder engagement, educational programmes or public outreach initiatives to raise awareness of marine biodiversity, ecosystem services, conservation challenges and sustainable practices.
Provide expert advice on marine resource use, fisheries management, marine protected area design or aquaculture systems; contribute scientific input to policy development and regulatory decision‐making.
Publish and maintain robust databases of marine biological data, archive specimens, manage metadata, and ensure data are accessible, reproducible and integrated with broader scientific or conservation networks.
Lead or support pilot or large‐scale studies on marine ecological processes (e.g., trophic dynamics, climate change effects, acidification, marine biotechnology) and translate findings into actionable insights or product development.
Contribute to internal strategic planning—help define research priorities, identify emerging marine science opportunities, propose new monitoring or management strategies and support organisational marine biology roadmaps.

Secondary Functions

Support ad‑hoc data requests, exploratory analyses or modelling of marine data to inform strategic decisions or project design.
Collaborate with product or engineering teams, environmental consultancies or technology providers to translate marine biology requirements into monitoring tools, software modules or decision‑support systems.

Required Skills & Competencies

Hard Skills (Technical)

Strong understanding of marine biology, oceanography, marine ecology, species interactions, habitat function and ecosystem processes.
Field sampling techniques in marine environments including scuba diving, boat‑based surveys, benthic and pelagic sampling and underwater equipment operation.
Proficiency in laboratory methods: specimen preparation, microscopy, molecular assays, water chemistry analysis, imaging and species identification.
Competence with geospatial tools and techniques (GIS, remote sensing, mapping software) for marine habitat mapping and spatial analysis.
Skilled in statistical data analysis, modelling and interpretation of ecological and marine datasets (e.g., R, Python, Excel) and ability to draw scientifically valid conclusions.
Familiarity with environmental regulations, EIA protocols, resource management, marine ecosystem conservation policy and stakeholder consultation.
Experience developing and managing monitoring programmes, method design, data management systems, quality control and documentation workflows.
Strong technical writing and communication skills: scientific reports, publications, policy briefs, outreach materials and presentations.
