WOODBURY - A marine research group is looking to launch a great white shark expedition off Long Island.

OCEARCH says it plans to find and tag juvenile great whites in the waters off the Island.

The organization says sharks are the key to our ocean's ecosystems, yet very little is known about their migratory patterns, and mating and birth sites.

OCEARCH has launched a Kickstarter campaign to raise the money needed for the expedition.

Researchers say the sharks are a sign of a healthy ecosystem, but swimmers should be cautious.

The sharks follow their food supply — which is great for Long Island's fishermen — but a tagged great white named Mary Lee was recorded swimming close to East Hampton last month.
