Show Getting Accurate Data on Ocean Temperature A virtual floating thermometer has been made of the Los Angeles liner Calawall by the University of California, Califor-nia, says the Los Angeles Times. In an effort to obtain accurate data about the ocean's temperature for use In studying currents, the university, In co-operation with the Los Angeles Steamship- company, has Installed a thermograph in the engine room of the ship. Attached to the intake pipe of the engine is a tube of mercury. The other end Is attached to the thermograph. thermo-graph. As the sea water Is drawD into the Intake it flows over this mercury mer-cury tube, causing the mercury to rise and fall according to the temperature. A strip of paper ruled for days, hours and minutes automatically records re-cords the temperature at all times as the ship plows its way through the Pacific Pa-cific to and from Hawaii. Heretofore all study of ocean temperatures tem-peratures was made by dipping up buckets of surface water and placing a thermometer therein. I |
