Exploring the oceans The ocean floor By Tyler

How do scientist study the ocean floor? the ocean floor can be as far to 11,000 meters down… they can’t survive under the ocean without special equipment they can’t survive under the ocean without special equipment

Studying the ocean floor with sonar sonar stands for sound navigation and ranging sonar stands for sound navigation and ranging The sonar instruments send pulses of sound down into the ocean The sonar instruments send pulses of sound down into the ocean

Studying the ocean floor with ships People cant survive under high pressure so they had to make underwater vessels so they had to make underwater vessels that can survive under high pressures that can survive under high pressures

Studying the ocean floor by drilling Scientist use special equipment to cut cores or long tubes of rock and sediment Scientist use special equipment to cut cores or long tubes of rock and sediment
