Abstract: White sharks (Carcharodon carcharias\, Family Lamnid ae) are a circumglobally distributed apex predator with historical aggrega tions off the coast of Australia\, South Africa\, the eastern North Pacifi c\, and the western North Atlantic (WNA). In the WNA\, white sharks are co mmonly found off coastal waters between the Southeast U.S. and Gulf of Mai ne (GoM). In general\, the life history of this species (i.e.\, k-selected : late maturity\, long gestation\, few offspring\, and prolonged longevity ) makes them highly susceptible to fishing pressure. Within the WNA\, youn g-of-the-year (YOY)\, juvenile\, and adult white sharks exhibit spatiotemp oral overlap\, however\, adult white sharks appear to have a more offshore distribution\, occupy colder temperatures and have more extensive vertica l (i.e.\, depth) movements. For YOY and juvenile white sharks\, recent wor k has suggested the presence of a nursery habitat in the New York Bight wi th recent observations suggesting an increased presence of juvenile white sharks in Maine’s coastal habitats. White sharks have the capacity to el evate their core body temperature above ambient via the retention of heat from counter current heat exchangers\, allowing for a potential expansion into colder habitats. With ongoing ocean warming at an extreme rate in the GoM\, understanding the thermal biology of juvenile white sharks will giv e insight into how their home range may be shifting northward (i.e.\, home range expansion)\, with the presence of a potential nursery habitat in th e GoM. To investigate this hypothesis\, a tag package containing a video\, depth\, activity\, and several temperature loggers will be deployed on ju venile white sharks caught utilizing land-based shark fishing methods off Maine’s coastline. A long-term acoustic transmitter and short term satel lite tag will be deployed in tandem to the tag package to determine the in dividuals geolocation. This study will increase our knowledge on the roles the GoM may play for successful juvenile white shark development in the W NA and how this species can be better managed/regulated in developing land -based shark fisheries.
