Cascadia Channel

The Cascadia Channel is like a special pathway in the ocean that allows water from the Pacific Ocean to flow into the deeper part of the ocean near the coast of Canada and the United States. But why is this important? Well, the water that flows through this channel is very rich in nutrients that help feed tiny organisms called plankton. These plankton are like the building blocks of the ocean food chain, providing food for larger animals like fish, whales, and dolphins. The Cascadia Channel also plays an important role in regulating the temperature and salinity of the ocean, which affects the climate and weather patterns. So, even though we can't see it from land, the Cascadia Channel helps keep the ocean healthy and provides food for creatures big and small.
