Some local U.S. Coast guards took their first trip up the Penobscot river since the big winter storm to break ice.
The goal is to see where the ice line is and start to break it up. That way, when spring arrives there will plenty of open water for any of the upriver ice to flow freely.
Chief boatswain mate Einar Mattson said '"We want to essentially create some flood prevention for the spring time."
They can break up to 12 inches of ice, however any big snow pack makes it more difficult.
Depending on how thick the ice is that's going to determine the speed of the boat.
Visibility plays a big factor in ice breaking.
"We only break when we can see we don't break at night and we don't break in low visibility" said Mattson.
It can also be damaging to the boat if they don't take proper precautions.
Michael Fonseca shooter technician first class engineer petty officer on board said "Damage to our propeller, our Rutter, our steering systems due to ice."
Working as a team is how they get things done in a timely manner.
Every coast guard member has a different duty.
"I'm responsible for machinery on board and the safety of every one on board" said Fonesca.
Seaman Daniel Shott said "When we're out here breaking ice I'm rotating with the bridge crew."
The amount of ice will determine how many times they go out a year.
"This year it's been colder so there's been a lot more ice so we've been out almost every week" said Fonesca.
Even though their hard at work they still think it's an amazing experience.
"We get to take a vessel and use it to break things with, which you normally try to avoid" said Mattson.
