Boundary condition modifications for 1992 run

Although the temperature and salinity boundary conditions obtained from the climatology and the western Gulf of Maine adjunct model result in a quite realistic representation of the observed temperature and salinity structure in Massachusetts Bay, actual data obtained near the boundary during the simulation time period can further improve the representation. To improve the 1992 water quality ``verification run'', several sets of CTD data were obtained from the National Marine Fisheries Service (Holzwarth-Davis and Taylor, 1993) and used to make very low-frequency (weeks to months) corrections to the temperature and salinity conditions.
