From February to May, two research teams share migration data from the California coast. Northbound whales are counted during their 5,000 mile journey from nursery lagoons in Mexico to feeding grounds in the Arctic. This "point count" method of tracking can help us see how the migration ebbs and flows. What migration patterns will emerge this season?
