C6047 US Coast Guard helicopter

I heard a helicopter fly over the island this morning, per Flightaware.com it was C6047, a Coast Guard helicopter.

I tried listening to the Door County fire and rescue channel on Broadcastify but heard nothing.

It looks like they flew up from Sturgeon Bay and then looked around St. Martin island for a while and then flew back to Sturgeon Bay.

it took me a while to get out of the chair, put on my coat, get the camera and then get outside

Was this a training flight or a possible rescue/assistance flight ?  I'll have to see if the Coast Guard publishes some kind of incident report - my limited understanding of the military is that NOTHING escapes a report to the higher ups.
