Marine Geochemistry

Marine geochemistry is a fascinating field that combines the principles of geology, chemistry, and oceanography to study the chemical composition and processes within the ocean. Professionals in this field play a crucial role in understanding marine ecosystems, climate change, and natural resource management. However, the unique skill set required for marine geochemistry also translates well into several other career paths. In this article, we’ll explore some alternative career options for individuals with a background in marine geochemistry.

Environmental Chemist

Environmental chemists study the effects of chemicals on the environment and human health. They analyze samples from air, water, soil, and other environmental sources to assess pollution levels and develop remediation strategies. Like marine geochemists, environmental chemists need a strong foundation in chemistry and an understanding of geological processes. They may work for government agencies, consulting firms, or research institutions, tackling issues such as water quality, waste management, and environmental policy.


Oceanographers study various aspects of the ocean, including its physical properties, currents, marine life, and ecosystems. They use a combination of fieldwork, laboratory analysis, and computer modelling to explore ocean dynamics and their impact on climate and weather patterns. Marine geochemists interested in broader oceanographic research may find this career path appealing. Oceanographers often work for government agencies, universities, or nonprofit organizations, contributing to our understanding of the world’s oceans and their role in the Earth system.


Hydrogeologists investigate the distribution, movement, and quality of groundwater resources. They assess groundwater contamination, design water supply systems, and manage groundwater resources for various uses, including drinking water supply, agriculture, and industrial applications. Given their expertise in aqueous chemistry and geological processes, marine geochemists can easily transition into hydrogeology roles. Hydrogeologists work in consulting firms, government agencies, and academia, addressing critical water resource management and sustainability issues.


Geochemists study the chemical composition and processes of Earth materials, including rocks, minerals, and fluids. They investigate the formation of geological features, the evolution of the Earth’s crust, and the interactions between different Earth system components. Marine geochemists possess valuable skills in analyzing aqueous samples and understanding the geochemical cycles operating within the ocean. Transitioning to a career as a geochemist allows individuals to apply their expertise to terrestrial environments, exploring topics such as mineral exploration, environmental remediation, and planetary science.

Environmental Scientist

Environmental scientists study the interactions between human activities and the natural environment. They assess environmental impacts, develop conservation and sustainability strategies, and conduct research to address pressing environmental challenges. Marine geochemists interested in a multidisciplinary approach to environmental issues may find a fulfilling career as environmental scientists. They can work in diverse settings, including government agencies, nonprofit organizations, and private sector companies, contributing to efforts to protect natural resources and mitigate environmental degradation.

Climate Scientist

Climate scientists study the Earth’s climate system, including its atmosphere, oceans, ice caps, and land surfaces. They analyze historical climate data, develop climate models, and investigate the causes and impacts of climate change. Marine geochemists interested in the intersection of chemistry, geology, and climate science may pursue a career as a climate scientist. They can contribute their expertise to understanding past climate variations, projecting future climate scenarios, and informing local, national, and international climate policy decisions.

While a career in marine geochemistry offers exciting opportunities for research and exploration of the ocean environment, individuals with this expertise also have a wide range of alternative career paths. Whether studying groundwater resources as a hydrogeologist, exploring Earth’s geochemical processes as a geochemist, or addressing pressing environmental challenges as an environmental scientist, the skills and knowledge gained from marine geochemistry are highly transferable. By considering these alternative career options, marine geochemists can pursue diverse and rewarding professional pathways beyond traditional research and academia, making meaningful contributions to various fields related to Earth and environmental sciences.
