Marine Geologist

Marine geologists operate within the office, field, and laboratory. In each of these settings, individuals in this occupation carry out various duties.

The office:

• Use geological data and research tools to analyze marine sediment samples, rock formations, and seismic data.
• Compile findings from field and laboratory research into reports, scientific papers, and presentations for the scientific community and public stakeholders.
• Design research projects, including defining objectives, budgeting, scheduling, and coordinating logistics for field expeditions.
• Create and manage GIS databases to map marine geological features and analyze spatial data.
• Collaborate with scientists, engineers, and environmental managers to integrate marine geological data into broader environmental and engineering projects.
• Prepare proposals to secure funding from governmental agencies, research institutions, and private foundations for new research projects.

The field:

• Conduct fieldwork to collect rock, sediment, and water samples from various marine settings, including beaches, the ocean floor, and underwater structures.
• Operate sonar, seismic, and other geophysical instruments aboard ships to map and analyze seabed structure and underlying geology.
• Assess the impact of natural and anthropogenic changes on marine geological environments, including monitoring erosion, sedimentation, and pollution levels.
• Participate in scuba diving operations to directly observe and collect geological samples from underwater locations.
• Record geological field observations, including noting rock formations, fault lines, and other significant geological features.
• Ensure field operations comply with safety standards and coordinate logistics for remote or challenging fieldwork locations.

The laboratory:

• Use laboratory equipment to analyze rock and sediment samples' chemical, physical, and biological composition.
• Use microscopes to examine microfossils and mineral grains within geological samples, aiding in the reconstruction of past environmental conditions.
• Interpret results from various analyses to understand geological processes and histories, such as sediment deposition rates and tectonic movements.
• Calibrate and maintain laboratory instruments for accuracy and reliability of sample analysis.
• Conduct controlled laboratory experiments to simulate geological processes and test hypotheses related to marine geology.
• Collaborate in research with scientists to integrate geological findings with oceanographic, biological, and chemical data for comprehensive environmental studies.
