The ocean has captivated mankind since the beginning of time. The Challenger Expedition‚ the first modern oceanography expedition‚ only began in 1872(“History of Oceanography”). Why was it that we ignored ocean research for so long? We have only “dipped our toes in the water” (Cousteau 194) and many people are afraid of taking a dive. However‚ ocean exploration is most certainly worth the risks‚ as the benefits of ocean research far outweigh the risks. Just two benefits of ocean research include

However ROVs are definitely not valuable they still have mechanical limitations‚ and human is definitely

This article from News and Views discusses the observation and analysis of submarine volcanic eruptions. Volcanism underwater is unalike volcanism on land due to the differing qualities of water and air. Air is not as dense as water; the properties of air allow for larger eruptions than those that occur underwater (Mitchell 444). Pressure on the ocean floor does not allow water or gasses to escape from lava. This causes the eruption to have less of an impact underwater than it would if it were on
