Before Gawley was muzzled from talking to me, he told me the monitors at ANP station could not pick up any data from the cruise ships. But what does that matter? We know them to be horrific polluters even if the wind blows up country.

The EPA did a study that found a cruise ship of 3,500 passengers berthed or anchored emitted the same deadly Sulfur Dioxide as 35,000 idling semi trucks. During the summer season the wind rose for Boston shows a prevailing SW wind that blows directly at Acadia National Park. Carnival Cruise Lines Homeports out of Boston and often sails directly to Bar Harbor. If the ships speed of 23 knots matches a 23 knot SW wind then they will be arriving in Bar Harbor along with a huge cloud of Sulfur Dioxide.

One thing that worsens this is the ship while under way is burning at least 3 times the diesel as it was anchored or berthed. Approximately 100,000 trucks idling 1 gallon per hour. If the wind matches the ship speed then over the course of their 10 hour trip from Boston to Bar Harbor a cloud, 10 times the 100,000 idling trucks, will arrive in Bar Harbor. That is 1 million idling trucks worth of SO2.

The EPA specifies no idling semi trucks should be left on for more than 5 minutes within 1000 feet of a school or population center.

Cruise ships are a major source of air pollution for MDI, ANP and especially Bar Harbor.
