Welcome to the Sea Watcher app! Here you can log your sightings of whales, dolphins, seals and other megafauna (basking sharks, ocean sunfish and sea turtles) anywhere in the UK and European waters. Whether walking along the coast path, watching from a clifftop or spotting from a boat, the Sea Watcher app will help you identify what you saw and record all the information that will be useful to help us understand more about all these marine species in the UK and European waters! The information you collect will be used to understand which species are seen where and when, and to highlight changes over time. It is also important to record when you are looking out for marine wildlife but donβt see any. You will be able to revisit your sightings as well as find out what others have seen around the British Isles in the last week, month or year. We hope you enjoy using this app and that it helps you to become a confident and regular Sea Watcher!
