I spoke with a caretaker today and he said it is up to NOAA to replace and they are based in Alabama. Apparently the signal goes to a SAT then alabama then is posted. Not sure when they will be in this area to replace.
The NOAA National Data Buoy Center is located in Stennis MS (at Stennis Space Flight Center campus);they operate the sensors at TPL and provide the data. I do not have any information on why the reporting has been interrupted, or the length of time until it returns.
