Show Getting Accurate Data on Ocean Temperature A virtual floating thermometer has been made of the Los Angeles liner Calawali 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 drawn 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 througli the I'a-clfic I'a-clfic 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. |
