The annual temperature changes are further repre- 
sented in the series of charts, figs. 5 to 10 on pp. 172 
and 175. 
Considering these, along with Table II, one sees at 
once that there are notable differences at the various Light 
Ship stations. The greatest extremes of temperature 
were observed in 1907 at the Liverpool North-west 
Vessel, and in the Solway, both of which stations are 
fairly near the land, and under the influence of the latter. 
The least annual temperature change was observed at the 
Carnarvon Bay Light Ship. The water at this point 
appears to possess a more truly “ open-sea”’ character 
than at any of the other stations investigated by us in the 
Irish Sea. ‘The maximum temperatures of the year were 
attained at the Cardigan Bay and Morecambe Bay 
Tight Ships; at the former station because of its more 
southerly position, and at the latter because of the 
influence of the Morecambe Bay sandbanks. The lowest 
Inish Sea temperatures were experienced at the Liverpool.
