National Marine Sanctuaries

Definition

National Marine Sanctuaries are federally designated areas within the ocean and Great Lakes waters of the United States, established with the aim of conserving and managing marine ecosystems of special national significance. These sanctuaries are critical for protecting the biodiversity, cultural artifacts, and ecosystem functions they encompass, serving as platforms for research, conservation, education, and sustainable use.

What is National Marine Sanctuaries?

The use of GIS in managing National Marine Sanctuaries involves designating specific geographic areas of the marine environment that hold special significance for research, conservation, and biodiversity protection. The process includes analyzing spatial, temporal, and functional relationships among marine creatures, their environments, and human influences. By employing spatial analysis tools, decision-makers can visualize and model these relationships, facilitating the creation of a strategic framework that ensures the protection and sustainable use of marine resources.

GIS technology plays a crucial role in understanding marine ecosystems by allowing the monitoring of changes over time, identifying critical habitats, assessing human impacts, and evaluating management practices. These insights help inform policy decisions about resource management, habitat restoration, and the establishment of protected zones within the sanctuaries.
