Figure 'a': Monthly mean surface temperature and salinity for
the entire duration of the record at the station which are derived
from simple averaging of all the monthly data.
Figure 'b': Monthly climatic average with the first standard
deviation. The standard deviation has been derived from the
difference in the monthly average from the long-term mean (1971 -
2000).
Figure 'c': Yearly anomaly from the base period. Where the
average base period (1971 - 2000) has been subtracted from the
average annual temperature and salinity. The standard deviation of
the annually averaged temperature and salinity of the entire record
is also shown. A trend line derived from a linear least squares
analysis has been added to indicate the extent to which annual
changes are linear.
