Professor Hans Paerl, left speaks with his assistant Jeremy Braddy on board the NCDOT ferry M/V Floyd Lupton on Friday, September 24, 2010. Few passengers know that in the Lupton’s engine room below, water is being collected from the Neuse River, where it enters the sound, for real time quality monitoring and data collection and further testing at the UNC Institute of Marine Sciences in Morehead City. It’s all part of FerryMon, a program which uses ferries to monitor water quality in the sound. \ SHAWN ROCCO — SHAWN ROCCO - srocco@newsobserver.com
