The first control year shallow profiles are generally greater than 5oC. There are
some lower values, however, including a couple between 0oC and 5oC and one
almost -5oC. In the final control year the shallow profile temperatures are
generally below 0oC at depths greater than 50m. The profiles are fairly tightly
bunched, more so than in the first control year, with only a couple of outliers.
The 1990 profiles are very similar to those of the last control year, with some
minor warming and spreading.
Deep profiles follow a similar pattern to the shallow profiles for the control
years. Between the first and last control years there is substantial cooling.
However, between the last control year and 1990 there appears to be continuing
cooling in the deep waters.
The results are not as clear-cut for salinity. The first control year is both fresher (for some shallow profiles) and saltier (for deep profiles). The last control run becomes more salty in shallow water and fresher in deep water and the spread of the values is reduced. The 1990 values are very similar to the last control run in shallow water but are even less salty in deep water. |

These comparisons further reinforce the observation that the climate model is too cold and too fresh in the Gulf of Maine. The two climatologies are essentially identical. The PCM Gulf of Maine profiles stand out as being different. Deep water climate model profiles are in reasonable agreement with the ocean climatologies. |

These comparisons additionally reinforce the observation that the climate model is too cold
and too fresh in the Gulf of Maine.
