Pig got of the geophysical geo geo- physical laboratory It consists of a walled thick cylinder with a plunger lunger that can be driven forward by y a charge of cannon powder Attached Attached At- At Is a ten foot tube of tern tern- cred steel which is called the bit When Then this sampler comes into contact contact con- con tact act with the bottom the powder is exploded and the bit Is driven into the he ocean floor Sample Comes up In Tube The bit Is lined with a thin brass tube ube which is removable The ocean cean bottom sample remains InthIs inthis in thIs its to be corked up and filed flied away for or study In the laboratories on shore A new lining is shoved into the bit the powder chamber in the theun gun un reloaded and the sampler is ready eady to take another bite The first real water deep-water samples were taken through the cooperation opera co tion on of one of the great commercial commer- commer cial ial cable companies which had to send lend out a powerful repair ship the Lord ord Kelvin to mend a break ina in 10 I a trans trans Atlantic cable |
