A project to map the bottom of Cobscook Bay – which has claimed the lives of at least 14 fishermen in the last six years – is now underway. A three-person crew from the National Oceanic and Atmospheric Administration arrived yesterday in Eastport. Their job is to survey the bottom of the bay, along with parts of the Bay of Fundy. Coast guard officials say they’re looking for formations and hazards that could cause trouble for ships, especially those that drag for fish.Last year, five people died when two dragging ships went down. Local sea pilot Captain Robert Peacock headed up the effort to bring the survey team in.He says the last time some parts of the area were mapped was more than a century ago.Officials say the current work should finish in the fall and a new map of the waters will be available by the end of the year.
