Study: Great white sharks are swimming farther and deeper
BOSTON — The movements of great white sharks in the Pacific and Indian oceans have long been the subject of academic study, but new research is just starting to shed light on the behaviour of their Atlantic Ocean counterparts.
Researchers in Massachusetts say white sharks appear to venture offshore farther, with more frequency and at greater depths than previously known in the Atlantic.
Some of the 32 sharks tracked between 2009 and 2014 ended up as far east as the Azores, the Portuguese island chain located more than 2,300 miles (3,701 kilometres) from Cape Cod, where most of the animals were initially outfitted with satellite tags.
They also were found to make frequent deep dives — as far down as 3,700 feet (1,127 metres) — and spend more time at those dark depths than previous studies in the Atlantic suggest.
