Marinewide

Marinewide is an adjective describing phenomena, distributions, or actions that span the breadth of the oceans. It is used to indicate scale and connectivity that extend beyond single habitats, ecosystems, or political boundaries, encompassing processes or characteristics that occur across multiple marine regions or basins.

In ecological and biological contexts, marinewide patterns include species ranges that cross ocean basins, dispersed larvae that travel across regions, and migration routes that link distant populations. In oceanography and climate research, marinewide analyses examine large-scale circulation, heat content, and acidification impacts that affect oceans globally. In fisheries and conservation, marine-wide assessments synthesize data across jurisdictions to evaluate stock status, biodiversity, and ecosystem resilience.

Challenges include uneven data coverage, methodological differences across studies, and governance across jurisdictions for data access and management of shared resources, especially in the high seas. Advances rely on international collaboration, standardized sampling, and data integration platforms to support comparative analyses across basins.
