Great White Migration Patterns
Researchers track Mary Lee the great white shark to document long distance seasonal movements between feeding and breeding zones. These journeys reveal how individuals use ocean currents, temperature gradients, and coastal features to optimize energy use.
By compiling data from multiple tagged sharks, scientists identify corridors where conservation effort and vessel management can reduce collision and bycatch risks.
Role in Marine Ecosystem
As Apex Predator
Mary Lee influences population dynamics of seals, sea lions, and mid size fish, helping maintain balance in the Northwest Atlantic ecosystem. Her predatory behavior supports nutrient cycling and can indirectly affect fisheries productivity through trophic cascades.
Indicator of Ocean Health
Tracking data from Mary Lee and similar individuals provides early signals of shifts in prey distribution, water temperature, and habitat availability, informing climate related research and policy decisions.
Research Methods and Tagging
Capture and Tagging Process
OCEARCH and partner teams use a specialized lift to bring the shark to the surface briefly, collect biological samples, deploy satellite tags, and release her with minimal stress. Each tag transmits location data when the fin breaches, creating a real time migration map.
Data Sharing and Collaboration
Publicly shared datasets from Mary Lee support academic studies, educational curricula, and interactive tracking platforms that engage students and citizen scientists worldwide in shark biology and conservation.
Conservation and Public Engagement
Mary Lee the great white shark illustrates how charismatic megafauna can focus public attention on marine protection. Online followers follow her voyages, which translates into broader support for habitat protection and sustainable fisheries initiatives.
Policy makers reference these high profile tracks when designing marine protected areas and bycatch reduction measures that consider wide ranging species.
