Fine-scale ocean processes in the Northwest Pacific and adjacent marginal seas play an important role in shaping marine ecosystem variability and biogeochemical cycling. Features such as fronts, eddies, and other dynamically active structures can influence nutrient distributions, biological productivity, and carbon-related processes, yet the mechanisms linking physical variability to ecological and biogeochemical patterns remain incompletely understood.

This study examines physical–biological coupling in Pacific–Asian marginal seas, with a focus on how fine-scale ocean variability may organize ecosystem structure and carbon cycling across dynamic marine environments. Particular attention is given to the relationship between ocean physical structure, surface biological variability, and broader biogeochemical responses in the region.

By improving understanding of how physical processes shape marine ecosystems, this work aims to contribute to a more integrated view of ecosystem variability and carbon cycling in the Northwest Pacific and surrounding marginal seas. The study is motivated by the growing opportunity to investigate these interactions across finer spatial scales and in greater regional detail than previously possible.
