Abstract

Abstract SYNOPSIS This paper is largely a summary of water-surface temperature comparisons by the author on a winter-time West Indies cruise of The R. M. S. Empress of Britain. An attempt was made to determine the accuracy of observational methods under a great variety of conditions, including the most trying ones likely to be experienced. Temperatures obtained nearly simultaneously (1) from a low deck with a 2 or 4 quart tin bucket by quick dips forward of the ship's main outtakes and (2) aft in the propellor wash, and (3) in the discharge from faucets attached to the condenser intake pumps, were consistent always within 0.25° F., and differed, on the average, but 0.1°F. Reliable results are evidently procurable from the stern, where “surface” observations may, perhaps, most accurately and readily be made in cold windy weather. A record from the condenser intake pipe appears truly representative of the surface temperatures under virtually all conditions. The condenser intake temperature recorded by engin...
