3D Habitat Use of YOY White Sharks


The objectives of this research are to examine fine- and broad-scale movements, habitat use, site fidelity, and residency of YOY and juvenile white sharks in the northwest Atlantic Ocean using multiple technologies including passive acoustic telemetry and satellite-based tagging. We are tagging white sharks with individually coded acoustic transmitters, as well as pop-up satellite (PSAT) and real-time satellite (SPOT) tags. Shark residency and movements are passively tracked using coastal acoustic receiver arrays.  Short-term PSATs will provide high-resolution vertical movement (depth and temperature) data within the nursery area, and SPOTs will provide accurate long-term horizontal movement data.  These technologies will help refine our understanding of how these young sharks use their summer nursery area (in three dimensions), and identify habitat preferences, migration corridors, and overwinter habitats.  This information will also help assess YOY white shark exposure to potential anthropogenic impacts (fishing, offshore energy development, coastal habitat degradation, etc.).
