Over 100 great white sharks detected off Maine coast

Over the last 13 years, more than 100 great white sharks have been spotted off the coast of Maine. Most of these sightings happen during the summer months and in shallow waters. Recent research aims to explain this trend. The study was a collaborative effort involving the Maine Department of Marine Resources, the Atlantic White Shark Conservancy, the Massachusetts Division of Marine Fisheries, and other organizations. The lead researcher, Matt Davis, expressed excitement about what the study reveals regarding white sharks in the western North Atlantic and Maine's coastal waters. This research is groundbreaking as it tracks white sharks over time in the region. The project began in 2020 after a swimmer was fatally bitten by a shark near Harpswell. In response, officials expanded their study of shark behavior in Maine. To gather data, researchers placed receivers along the Maine coastline. These devices detect sharks tagged off Cape Cod and Hilton Head, South Carolina. Their findings indicate that sharks tend to stay in waters less than 50 meters (164 feet) deep, with peak sightings from July to September. What's notable is that many detections occurred during the day when beaches are busy. Areas like Ogunquit and Kennebunk saw some of the highest shark sightings. However, Maine's detection rates remain low compared to regions like Cape Cod, known for its frequent shark activities. Despite the increased sightings, researchers believe there is no significant risk to humans. Sharks are essential for the marine ecosystem, helping to regulate other species. Their presence may indicate a healthy marine environment in Maine. Scientists hope their findings will help develop effective management strategies. This will allow better communication with the public about enjoying Maine's beaches safely, as shark conservation efforts continue without compromising human safety.
