This paper explores the potential of subsurface carbon sequestration in offshore environments from a geoscientific perspective. It highlights the significance of carbon sequestration in mitigating climate change and outlines the objectives of investigating the feasibility and challenges associated with offshore subsurface storage. The paper delves into the mechanisms and advantages of offshore carbon sequestration, examining geological characteristics, reservoir assessment, and seismic imaging. It also addresses the challenges and risks, both geological and technological, to provide a comprehensive understanding of the complexities involved. Real-world case studies and ongoing research initiatives are discussed to showcase successful projects and emerging trends. The economic and environmental implications are analyzed, emphasizing the need for thorough cost-benefit analysis and environmental impact assessments. The regulatory framework and compliance standards are explored to ensure responsible implementation. The paper concludes with insights into future prospects, including emerging technologies, research priorities, and the importance of responsible practices. The exploration aims to contribute to the growing body of knowledge guiding sustainable solutions for carbon reduction in offshore environments.This paper explores the potential of subsurface carbon sequestration in offshore environments from a geoscientific perspective.
