Coastal Marine Lab


Coastal Marine Laboratory Monitoring Station (Newcastle, NH)
The Fort Point sonde is deployed in a perforated pipe attached to a piling at the end of the University of New Hampshire's pier adjacent to the US Coast Guard Station. This instrument measures the water conditions at the point where the ocean and the Great Bay Estuary meet, providing data on water masses entering and exiting the system.
