VOYAGE OF THE SCOTIA, 1902-1904. V 



There were several Robinson anemometers on board, but these were not employed 

 while the ship was at sea. 



State of the 8ea. 



The direction of the motion of the sea was noted, as in the wind observations, by the 

 ship's steering-compass, and the data reduced to the true meridian. 

 The sea disturbances were noted on the following scale : — 



— dead calm. 5 — rather rough. 



1 — very .smooth. 6 — rouoh. 



2 — smooth. 7 — high. 



3 — slight. 8 — very high. 



4 — moderate. 9 — tremendous. 



Solar Radiation. 



A black bulb solar radiation thermometer m vacuo was freely exposed in a stand 

 fixed to the bridge, and the maximum temperature read at sunset. 



Surface Sea Temperature. 



The temperature of the sea-surface was, as a rule, observed every four hours, but the 

 data obtained are discussed in the report dealing with the Physics of the Ocean.
