![]() OCEARCH, an organization focused on researching great white sharks, has a great tool called the Global Shark Tracker that allows scientists and members of the public alike to keep track of the many sharks that have been tagged off the US Atlantic coast and elsewhere around the world. You can join marine researchers who are tracking shark’s movements online by using Global Positioning Satellite (GPS) and GPS live tracking software using the ARGOS constellation of satellites. Somewhere in the world, a shark is going about its business swimming in the ocean.

Other tags have popped up in New Caledonia, Vanuatu, and half-way to Tonga. This huge range in temperature is very unusual among fishes,” Dr Francis says. “Previous tagged white sharks have dived as deep as 1000 metres and encountered temperatures ranging from 3 degrees in deep water to 24 degrees in shallow tropical waters. Once all the data has been transmitted from the latest shark, the project team will be able to determine the route the shark took, how deep it dived, and the water temperatures it experienced. Two tags have failed but we still have six more tagged sharks in the water which are due to report back between October and January, offering us an amazing insight into the secret lives of these apex predators.” This year has greatly added to our tally with three more being tagged at Stewart Island and six more at Chatham Islands. “Until this year we’ve only been able to tag six white sharks in three seasons of field work. NIWA fisheries scientist Dr Malcolm Francis says this has been a bumper year for white shark tagging. ![]() The shark tagging project, which began in 2005, is an international collaborative programme being run by the National Institute for Water & Atmospheric Research (NIWA), DOC, and Dr Ramon Bonfil from Shark Tracker/NABU (Germany). ![]() "This is only 100 kilometres from where another tag popped up last year from a shark tagged at Stewart Island after having travelled over 3000 kilometres," says Mr Duffy. The satellite tag popped up at Swain Reefs, off Rockhampton, late in August. ![]() ‘Thomas’ was tagged by Department of Conservation (DOC) scientist, Clinton Duffy, off Ruapuke Island in Foveaux Strait, in February. The tag records information on light levels (from which approximate daily latitude and longitude can be estimated) as well as water depth and temperature so that the shark’s movements can be tracked.Īfter a predetermined time (six months for this shark) the tag pops off the shark, floats to the surface and transmits the data to a satellite that emails the information back. The 3.5 metre shark, nicknamed ‘Thomas,’ was tagged with a popup archival satellite tag. Another tagged New Zealand great white shark has migrated to the Great Barrier Reef off Australia – 1 of nine sharks to be satellite tagged this year. ![]()
