Tracking Great White Sharks on Cape Cod - With Shark Expert Greg Skomal
9In this video Ryan McVinney with Boat Trader discusses tracking great white sharks on Cape Cod with Greg Skomal, PhD, an accomplished marine biologist, fisheries biologist, great white shark expert and underwater explorer. Skomal has worked with the Massachusetts Division Marine Fisheries (DMF) for over 30 years and heads up that state agency's great white shark research. He and the Save The Seas Foundation conduct research on the coast of Cape Cod in the Atlantic Ocean. The interview delves into the species of sharks in the Northeast and how the researchers tag, track and study white sharks on Cape Cod, specifically researching the behavior of this species in the New England region to understand the ways in which these sharks hunt their prey (including jumping our of the water to prey on seals), the frequency of feeding events and the environmental factors that drive their overall behavior and migrations. In his research, Skomal, along with the Save Our Seas Foundation, uses an innovative approach that combines accelerometry with tag-mounted video cameras and bio-energetic modeling to enable them to closely examine the predator–prey relationship between white sharks and grey seals in the waters off Cape Cod. Accelerometer tags, which record fine-scale three-dimensional movements, tell the scientists the shark’s tail-beat frequency, amplitude, body posture and swimming depth at sub-second intervals. This gives them a detailed picture of individual white sharks’ behavior and allows the team to identify the location and frequency of their predation attempts. Skomal and his team couple this technology with camera tags, which provide direct observations of white shark behavior. These data will be used to estimate energy expenditure and feeding requirements of white sharks off Cape Cod so as to quantify seal predation rates while taking into account the environmental conditions that correspond to predatory activity. Shark identification (i.e. basking sharks vs great white sharks) is covered with photos of over 400 tagged sharks and advice on how to identify shark species in the wild.
