Understanding the physical, chemical, and biological characteristics of our oceans is foundational to addressing planetary health. Oceanography & marine science investigates processes such as ocean circulation, biogeochemical cycling, and deep-sea ecosystem functioning, offering critical insight into how marine environments respond to climate change. Ocean acidification, warming currents, and biodiversity loss are driving researchers to develop high-resolution models and autonomous observational platforms for better data integration. Coastal zones, vulnerable to sea level rise and habitat degradation, are receiving increased attention due to their ecological and economic importance. In exploring how carbon is sequestered in oceanic systems and how marine organisms adapt to environmental stressors, Oceanography & Marine Science contributes not only to climate regulation understanding but also to conservation planning and sustainable maritime resource use.
