What was the very first method of ocean exploration?

The first scientific expedition to explore the world's oceans and seafloor was the Challenger Expedition, from 1872 to 1876, on board the British three-masted warship HMS Challenger.

What device was used to study the ocean's floor?

Sonar can be used to measure how deep the ocean is. A device records the time it takes sound waves to travel from the surface to the ocean floor and back again.

How has technology impacted the study of the ocean?

Today, buoys and water column samplers are used to monitor sea surface conditions and water quality factors, coring devices collect sediment samples, sonar helps create maps of the seafloor, and remotely operated vehicles (ROVs) allow us to safely and efficiently explore all parts of the ocean.

How was the ocean discovered?

Ocean satellites, scientific buoys, deep sea submarines, and advanced sonar have only been used in ocean exploration for the last 50+ years. And as this technology improves, scientists have been able to discover more of the oceans and map a greater percentage of the ocean's floors.
