Ecological Marine Units – GIS Provides Better Understanding of Ocean Ecosystems: “A healthy ocean can reduce poverty, combat hunger, limit the impacts of climate change, and improve the global economy. To achieve these ideals and support ocean sustainability, it is necessary to have a baseline method for understanding of the ocean’s ecosystems and a framework to detect change. Ecological Marine Units (EMUs) are the baseline 3D mapped ecosystems of the ocean that have been classified through statistical clustering.”
