Cleveland (AP) -- The Coast Guard has sent a second ice cutter to keep Lake Erie shipping lanes clear.
The Cutter Penobscot Bay arrived in Cleveland last month from Bayonne, N.J. It will join the Neah Bay in ice-cutting duty for the winter.
Both are 140-foot bay class icebreaking tugs that can cut through 22 inches of ice by running at 3 1/2 miles per hour.
They can break thicker ice with a ramming technique.
The icebreakers also handle search and rescue work and help break up river ice jams that can cause flooding.
