Cold water currents are large-scale movements of cold water in the ocean. These currents typically flow from polar regions toward the equator, helping to regulate global climate by distributing heat. They can influence weather patterns and marine ecosystems, affecting the distribution of nutrients and marine life. One well-known cold water current is the California Current, which flows southward along the western coast of the United States. This current brings cooler temperatures to the region and supports diverse marine habitats, making it important for both local fisheries and wildlife.
