Events will take place between July 25 and 29.
The postal office will have the temporary station set up at the official Cape Cod Canal Centennial celebration at Buzzards Bay Park.
The town expects a large crowd and town hall's parking lot is a designated parking area for the celebration.
The program's name comes from the manner in which many young people first become curious about marine life, by lying on their belly on a dock and gazing down onto what is living underwater.
Also confirming their intentions to attend the summit are Representative Randy Hunt and Representative David T. Vieira.
The Canal Crossways property comprises a little more than five acres off Main Street in Buzzards Bay.
Bourne police said that the incident was not criminal in nature.
Bourne Department of Natural Resources director and town harbormaster Timothy W. Mullen said there is to be no anchoring of vessels in the waters known as Red Brook Harbor, including all waters surrounding Bassetts Island.
Tall ships and training ships will be open for tours during the celebration.
