Data on marine environments, like coral reefs and sea life, is crucial for a cross-national marine planning tool. This data helps identify and protect areas with lots of different species, promoting conservation. It's important for understanding the value of marine areas, like fisheries, carbon storage, and storm protection. This info guides decisions for sustainable development. By combining national data, the tool can see how human activities affect marine environments over time, helping plan to reduce negative effects.

Sharing national data helps countries work together on cross-border issues like migratory species and pollution in marine planning. The data helps manage marine resources sustainably, especially in fisheries, by understanding fish distribution and habitats. National data contributes to understanding climate change impacts, aiding in developing strategies to address rising sea levels and changing marine conditions.

The data is a foundation for broader scientific research on marine ecosystems, advancing knowledge and guiding future decisions. National data is essential for creating effective policies related to marine conservation and management, ensuring decisions are based on accurate information.
