Another instrument which crowds the cabin of the Atlantis bears the unprepossessing name of Geomagneticelectro-kinetograph (affectionately known as the "geek") and measures temperatures difference in the water by exploiting changes in the earth's magnetic field in a long wire loop dragged behind the boat. Using the principles of this instrument, the Institute experimented last fall on the current that runs through the Florida straits by hitching up electrodes on either end of the Western Union cable that runs to Havana and measuring the potential between the ends. Calculation with the potential gave the amount of water that flows...
