STUDYING OCEANIC RIDGE-TRANSFORM SYSYTEMS
-MOST STUDIES USE SURFACE SHIP MEASUREMENTS OF GRAVITY, MAGNETICS, AND HIGH-RESOLUTION SONAR (SOUND WAVE) MAPPING
-OTHER MEASUREMENTS MADE WITH DEEP-SEA DRILLING
-SEISMOLOGY USED TO STUDY EARTHQUAKES AND CRUSTAL STRUCTURE
-DETAILED STUDIES USE MANNED AND ROBOTIC SUBMERSIBLES (SUBMARINES) THAT CAN SAMPLE ROCKS AND FLUIDS AND TAKE PHOTOS
-IN PLACES, OCEANIC CRUST (OPHIOLITES) IS EXPOSED ON LAND AND IS STUDIED THERE
