who were studying great white sharks by using satellite tracking tags. They identified a zone with a radius of approximately centered at approximately . The findings, which were initially published in the January 3, 2002 issue of the journal ''Nature'', showed three of four tagged sharks traveled to the Café during a six-month period after they were tagged off the central coast of California. Although the area had not previously been suspected as a shark habitat, when mapping the satellite tracking data, researchers discovered that members of the species frequently travel to and loiter in the area. It was once believed the area had very little food for the animals (researchers described it as the shark equivalent of a

), but research in early 2018 by the vessel ''Falkor'' showed that there is a rich and diverse food chain too deep to be detected by satellites that provides a potentially abundant food supply for the sharks.

While at the Café, they dive to depths of as often as once every ten minutes. By 2006, researchers had observed consistent migration and other behavior. Tracking data indicates that white sharks will leave feeding grounds near the coast in winter, travel to the Café, and some may even summer near Hawaii. But many linger in the Café, often for months, before returning to the coast in the fall, coinciding with the
