As part of the AFMIS/LOOPS/AOSN collaborative effort, a 3-day long updating survey in the Massachusetts Bay was carried out during September 2-4, 1998. This survey collected temperature, salinity, and chlorophyll profiles at selected stations in the Bay area.  Such data will be used for updating the Harvard Ocean Prediction System (HOPS).  The nominal cruise tracks are shown in Figures 1-3 for the three days.
 

Data note: data from the Seabird CTD continue to be plagued with significant noise and low values of salinity. In addition, the Seabird instrument broke down on the second day of the survey. As a result, only the data from the Falmouth Scientific instrument are presented here. Also note that only the downcasts have been included in the Harvard formatted data.
