HUSSEY (TAKING SEA TEMPERATURES), COMMANDER WILD AND McILROY
At the outset of the expedition the Air Ministry very kindly gave us every assistance, and lent us a great deal of apparatus and many instruments on the understanding that they would be allowed to use the information that we gathered. This arrangement has been carried out, and we hope that among the many scientific results of the expedition we have been able to add one link to the chain of observations which is being made daily all round the world, and so we may have justified our existence.
The instruments used consisted of the following:
(a) Two standard ships’ screens, in each of which were a wet and dry bulb thermometer. These were placed one on each side of the bridge, well exposed and as far as possible away from any draughts and convection currents from galley and engine-room. The readings were taken from the screen on the weather side.
(b) A marine-pattern mercury barometer, hung in the gyroscope-compass room, which was also used to check the ship’s aneroid which was placed in the wheel-house.
