FY 2025 Submarine volcanic eruptions and their impacts on hydrothermal systems and biological communities Carey, R.J., D.A. Butterfield, and M.R. Clark Annu. Rev. Earth Planet. Sci., 53, 397-423, doi: 10.1146/annurev-earth-040522-095654, View open access article at Annual Reviews (external link) (2025) More than 70% of Earth's magmatic output occurs in the ocean. This volcanism shapes major features of the seafloor, directly impacts the chemical composition of the oceans through water/rock interactions, and drives hydrothermal circulation of seawater. The formation of seafloor mineral deposits and chemosynthetic habitats that encircle the globe along mid-ocean ridges, volcanic arcs, and hotspots is driven by volcanism. The style, magnitude, depth, and frequency of seafloor eruptions create a wide range of physical, chemical, and biological impacts on the seafloor. Research and exploration over the past 30 years have revealed some of the diversity of seafloor eruptions and their impact on the undersea environment.
