The team at the University of Maryland Center for Environmental Science's Chesapeake Biological Laboratory are studying how often dolphins actually come into the Chesapeake Bay, how long they spend here, what areas of the Bay they are using and why. Chesapeake Dolphin Watch allows citizen scientists like you to report when you see a dolphin in the Bay. You simply point to where you saw the dolphin or use your current location and tell us about how many you saw. You can also include photos or videos to provide even more useful information to our team!

Cribbage Trainer's advantage is update cadence (every 8 days vs every 8 months). On price, ads and device support there is nothing between them.
