Scientists are hoping to attach electronic devices to as many as 20 great white sharks in the waters off the Cape this month.   They will try to learn why the big increase in the number of these feared creatures in those waters over the past few years.

The research vessel OCEARCH sailed out of Woods Hole on Tuesday.  Massachusetts scientist Greg Skomal told the Cape Cod Times that the goal is to find out as much as possible about the movement and behavior of the sharks.

A seller oat will be used to actually catch the sharks.  A hydraulic lift will be used to lift the sharks on to the deck of the research vessel where scientists will attach the electronic tagging devices before releasing the sharks back into the water.
