A significant rise in the population of great white sharks has been observed in the waters along the US coastline, as reported by the global non-profit ocean research organization OCEARCH. Between August 1 and August 10, OCEARCH’s tracking site detected 11 great white sharks in the eastern US waters.
Among these sightings is Contender, the largest great white shark ever documented by OCEARCH. Initially spotted in June heading towards a popular tourist beach, the massive predator has been repeatedly tracked on the ocean’s surface in August.
The recent surge in shark sightings contrasts with previous months, with July recording five white sharks and June only three. Avery McAlhany, a Content Specialist at OCEARCH, attributed this increase to the tagging and release of seven new white sharks in partnership with the Tancock Islands Marine Field Station in Atlantic Canada.
McAlhany explained that the frequent pinging of these sharks is common with fresh tags that are free from biofouling, enhancing signal clarity. OCEARCH’s research also revealed a new migration pattern among white sharks in the western North Atlantic, with many migrating to cooler waters in Atlantic Canada and New England during the summer months in search of abundant food sources like fish and seals.
Despite their intimidating reputation, great white sharks infrequently pose a threat to humans, often taking a single “sample bite” before moving on to other prey. While stories of their poor eyesight are exaggerated, these sharks rely on other senses to identify prey, sometimes mistaking surfers and swimmers for seals.
Experts recommend several precautions to avoid encounters with great white sharks, including being vigilant of signs such as circling birds, splashing water, and the presence of seals or dolphins. Wearing plain, dark-colored wetsuits is discouraged to prevent misidentification, with brightly-colored, patterned wetsuits suggested as an alternative.
Swimming during poor light conditions, swimming alone, or swimming with open wounds are additional risks that can attract sharks. Dr. Harley Newton, OCEARCH’s chief scientist and veterinarian, advises against wearing shiny objects while swimming and emphasizes the importance of maintaining visual contact if encountering a shark, slowly backing away while facing the predator.
While shark attacks are rare, staying informed about ocean dangers and following safety guidelines can help mitigate risks.
