Presentation of results
For each inshore temperature station, there is a Figure 'a':
Monthly mean surface temperature for the entire duration of the
record at the station which are derived from simple averaging of
all the monthly data.
For those stations with records from 1971 - 2000, there is a
Figure 'b' and Figure 'c':
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 temperature (1971 - 2000) has been subtracted
from the average annual temperature. The standard deviation of the
annually averaged temperature 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.
For the three stations with long records; Eastbourne, Dover and
Port Erin, two trend lines are presented, one covering the period
from 1965 - 2004, to match the figures above (a, b and c) and the
other over the entire record.
For the ferry route temperature and salinity data there is a
figure 'a', 'b' and 'c'.
Data are presented from three of the ferry route stations namely
Position 2, Position 4 and Position 7. These
stations have been selected from a group analysis as being
indicative of the trends in three separate regions across the
channel. Thus P2 represents stations P1, P2 and P3; P4 represents
P4, P5 and P6 and station 7 is indicative of P7, P8 and P9.
The monthly mean sea surface temperatures and standard deviation
for 38 stations around the English and Welsh coast are presented in
tabular format for all of the stations. For stations whose record
covers the base period of 1971 - 2000, the mean, count and stdev
from 1971 to 2000 is also presented.
For the ferry route data, the monthly mean sea surface
temperatures and salinity for 9 positions across the Southern Bight
of the North Sea are also available in tabular format.
