Talking about tuna. How do you read this picture. Rod Mr. Sundog, Brine Shrimp, Mark Mac, Wak and Stack, Han Solo, Puffin and others that can look and see by a picture where the tuna will be. Is this a good picture for that and if it is where would the tuna be. Way out in the blue water or close in around the green and blue? Mark mentioned this site but it is one I have been looking at for years. The water temp is so so and I am not sure it gets as detailed as ERDDAP for chlorophyll. But a good satellite photo.
