A device was developed by the Naval Civil Engineering Laboratory to determine the 

 short-term, in-situ bearing pressure and settlement response of marine sediments at any ocean 

 depth. Tests were performed in cohesive sediments with both round and square bearing plates 

 at ocean depths of 1,200 and 6,000 feet. During a typical test, measurement of load, settle- 

 ment, and attitude of the device were transmitted acoustically to a surface vessel where they 

 were monitored and recorded. The results of these plate bearing tests were found to be 

 amenable to analysis by modified elastic and bearing capacity theory. A tentative procedure 

 for predicting the short-term settlement of seafloor footings using the results of laboratory 

 tests on core samples was developed on the basis of these two approaches.
