Great white surprise: the well-travelled shark

In March, 2013, the non-profit, open-source research organization,¬†OCEARCH,¬†caught a four-metre, 900 kg, female great white shark off the Atlantic coast of Florida near Jacksonville, then released it after attaching monitoring and tracking devices. In the year since, the shark has travelled 31,000 kilometres, visiting Cape Hatteras, Bermuda, George’s Bank, Placentia Bay, and the Grand Banks, before crossing the mid-Atlantic ridge to a point 1200 kilometres off the coast of Ireland.

Shark's year of travel

In late October, Lydia, as the researchers nicknamed her. spent three days exploring Newfoundland’s Placentia Bay and Merasheen Island:

You can follow Lydia’s travels on OCEARCH’s interactive, live-tracking map. You can follow OCEARCH on Facebook, Twitter, and Instagram. Here’s a video of Lydia’s capture and tagging.

How big is that oil spill?

[Correction appended.] Google Engineer Paul Rademacher has produced a tool that will put a shadow the size of the Gulf oil spill anyplace on earth. (You may need to install the Google Earth Browser Plugin, which Rademacher developed, in your browser.) If the spill occurred off Sambro Island near Halifax, the slick would extend from Rose Bay, Lunenburg Co., in the west, to Port Bickerton, Guysborough Co, in the east:

Here it is on George’s (!) Bank, where Canada and Nova Scotia will soon decide whether to lift a moratorium on offshore drilling:
