METEOEOLOGICAL OB BEE Y ATI ON S 



AT 



LAURIE ISLAND, SOUTH ORKNEYS. 



Position of Station. 



From 1st April to 31st October 1903 hourly meteorological observations were made at 

 the winter quarters of the " Scotia " in Scotia Bay, during which time the ship was 

 frozen in at a distance of about 600 yards south-east of the Central Cairn, which is in 

 lat. 60° 43' 42" S., long. 44° 38' 33" W. On 1st November the hourly observations 

 were transferred from the ship to the shore, where a stone hut, named " Omond House," 

 had been built for the accommodation of the party who were to remain on the island 

 while the "Scotia" went north to refit at Buenos Aires. The observations taken on 

 the ship and the instruments in use were exactly similar to those described in the 

 introduction to the Sea Observations. In addition, a Robinson hemispherical cup 

 anemometer was placed about six feet above the level of the poop, during the wintering 

 of the ship, in a position where it was freely exposed to the prevailing winds. The 

 exposure was good, except from the west-south-west, but in that direction some hills 

 exerted a disturbing miiuence, making the winds squally and uncertain. A snow 

 gauge was also in use, but owing to the frequency of heavy drift its readings were 

 untrustworthy as a measure of the true precipitation, and I cannot bring forward the 

 results with any degree of confidence. 



Omond House Station. 



Soon after the arrival of the "Scotia" in winter quarters an auxiliary station was 

 established on the beach that here divides the north from the south side of the island. 

 Here were placed four screens containing the following instruments — one large and one 

 small Richard thermograph, one Richard hygrograph, dry and wet bulb thermometers, 

 a maximum and minimum thermometer, and a black bulb in vacuo registering maximum 

 thermometer. The Campbell Stokes sunshine recorder was placed on a cairn about four
