There is no record of a submarine called "Seawolf" punching through ice at the North Pole. The most famous submarine named "Seawolf" is a nuclear-powered attack submarine in the US Navy, which is capable of operating under the ice but has never been reported to have punched through it at the North Pole.

It's important to note that:

* Submarines do not "punch through" ice. They have specialized features that allow them to break through relatively thin ice, usually by using their powerful engines to push upwards and crack the ice.

* The ice thickness at the North Pole varies greatly and is generally much thicker than what a submarine could break through.

Therefore, it is highly unlikely that any submarine, including the Seawolf, has ever "punched through" ice at the North Pole.
