The travels of great white sharks (Carcharodon carcharias) equipped with the SPOT tags in both the Atlantic and Pacific Ocean have surprised researchers over the past month or so.
According to OCEARCH’s Global Shark Tracker, an adult female white shark (nicknamed “Mary Lee”) left Cape Cod waters last September and headed south, as researchers had expected. By the beginning January, Mary Lee had made her way to the waters off northern Florida, which was inline with the theory that Atlantic white sharks spend their time in waters off the southern states of the east coast of the United States during the winter months and then head north during the summer months when water temperatures rise.

"Genie," the first North Atlantic great white shark (Carcharodon carcharias) to be fitted with a SPOT tag, recently reported in not far off the coast near the Georgia and South Carolina border. According to the OCEARCH Global Shark Tracker, Genie’s tag reported data on December 9 around 11am. This marks the first time that the shark’s SPOT tag has reported data outside of Cape Cod waters.
Genie was originally tagged on September 13, 2012. Her satellite tag reported data multiple times during the month of September, while she remained in Cape Cod waters. The last ping, prior to the December 9 report was on September 30.
An OCEARCH tagged white shark (Carcharodon carcharias) reported in off the coast of South Carolina, east of Charleston last week. The shark, nicknamed “Mary Lee,” is an adult female measuring 16′ (5m) in length. She was originally tagged by the OCEARCH team in September off of Cape Cod. The SPOT (Smart Position and Temperature) tags report data when a tagged shark surfaces. According to tracking data, Mary Lee has been spending her time in coastal waters off of Georgia, Florida, and South Carolina coast over the past month.
OCEARCH is reporting that a female white shark tagged in South African waters was killed after being caught in a gill net in Mozambique waters. The shark, nicknamed “Brenda,” was tagged earlier this year in Mossel Bay by OCEARCH along with a team of South African researchers.
According to OCEARCH the shark’s carcass was harvested. Its meat was given to a local village, while its fins were sold. Eyes on the Horizon, a Mozambique NGO, were able to recover the SPOT tag.
Boston’s WDHD.com has posted a video of last week’s SPOT tagging of a female great white shark in Cape Cod waters. The white shark, nicknamed “Genie” after Dr. Eugenie Clark, was out of the water for 16 minutes during the tagging process. “Genie” was measured at 14′ 8′ in length and weighed in at 2,292 lbs, according to OCEARCH’s profile of the tagged shark.
The SPOT tag will report data each time the shark surfaces. You can follow “Genie” (along with other white sharks tagged in South African waters) online at OCEARCH’s Global Shark Tracker page.
