Southern Maine’s coastline has become a hotspot for shark activity this summer, with an uptick in sightings prompting caution from local authorities and sparking curiosity among residents and visitors. Several great white sharks have been captured on camera in recent weeks, leading to a noticeable increase in reported encounters along popular beaches.
Understanding the Rise in Shark Sightings
While the visual evidence of sharks near shore is undeniable, researchers emphasize that the surge in reported sightings is a complex phenomenon. Dr. Walt Golet, an assistant professor of marine sciences at the University of Maine, noted that while there’s a clear increase in reported sightings, determining if this directly correlates to a larger shark population requires careful consideration of various factors.
Matt Davis, a marine resource scientist with the Maine Department of Marine Resources, echoed this sentiment. He explained that favorable beach weather and the proliferation of drone technology, actively used by many individuals to spot marine life, significantly influence the number of sightings reported. “We’ve had great weather this year for beach tourism, and we also have a number of people with drones actively looking for sharks, so sightings are high,” Davis stated.
Scarborough Beaches: A Shark Hotspot
The town of Scarborough, a popular destination along the southern Maine coast, has been particularly active with shark sightings. Daryen Granata, the harbor master and marine resource officer for Scarborough, reported that the police department began receiving numerous reports in early July. “They were off of Pine Point Beach for a substantial amount of time,” Granata said. “They’ve kind of migrated now. They’re more off the Scarborough Beach State Park and Higgins Beach area at this point. We’re still seeing them on a daily basis. Still to this day, and it’s been, you know, three weeks at this point.”
Granata, a long-time resident of Scarborough, observed that shark sightings, especially of juvenile sharks, have become considerably more common in recent years. However, she also pointed out the role of technology in this increased visibility. “We have all this drone technology. We have all the cell phone videos. We’ve got a lot of higher-grade technology than we did, you know, 10 or 15, 20 years ago. So we’re seeing them,” she explained. The police department itself captures drone footage, as do independent photographers and beachgoers, with social media further amplifying the reach of these sightings.
Ecological Factors Driving Shark Presence
Experts suggest that the increasing presence of white sharks in the Gulf of Maine is linked to broader ecological recovery efforts. Following federal protections implemented in the 1990s, white shark populations have been slowly rebounding. Concurrently, Maine’s seal population has grown, providing a vital food source for these apex predators.
Davis believes this trend reflects a healthier ecosystem. “It’s very possible that the number of white sharks we see now is more reflective of their natural population size, or at least the closest it’s been to the natural population size in several decades,” he commented. “Think of this as a population success story in that the ocean is regaining one of its apex predators to help balance the food chain.”
Dr. Golet added that the abundance of prey species like striped bass and Atlantic menhaden along the Maine coast also contributes to the presence of juvenile white sharks. “It makes sense that you see this rebound especially since the generation time for white sharks is about 25 to 30 years,” Golet stated.
Warming Waters and Future Outlook
Looking ahead, researchers are considering the potential impact of warming ocean temperatures. As the Gulf of Maine continues to warm, it may become a more hospitable environment for sharks to inhabit for longer periods throughout the year. This could lead to more frequent sightings becoming a regular occurrence.
Long-time residents have noticed the shift. Kelsey Donohue, who has lived in Scarborough her entire life, remarked, “There are definitely more sharks in Maine than I’ve ever seen in my entire life.” She recalled a time when seeing sharks in Maine was considered highly unlikely. Betty MacLeod, another Scarborough resident, noted that sightings off Pine Point Beach, where a fatal shark attack occurred five years ago, were previously unheard of.
Safety Recommendations for Beachgoers
In light of the increased activity, the Scarborough Police Department is urging the public to exercise caution and stay vigilant when entering the water. Officials have provided several safety recommendations:
- Avoid Dawn and Dusk: Sharks are often more active during these times.
- Never Swim Alone: Always have a buddy when in the water.
- Stay in Shallower Waters: Limit swimming to waist-deep or shallower areas.
- Avoid Murky Water: Poor visibility can increase risk.
- Protect Open Wounds: Individuals with open cuts or sores should stay out of the ocean.
- Remove Jewelry: Shiny objects can attract sharks.
Granata summarized the advice with a simple reminder: “Just be cognizant of what you’re doing and where you are. Just have good situational awareness, that’s all.” By following these guidelines, beachgoers can enjoy the coast while minimizing potential risks associated with the growing shark population.
