Well one reason we should not do space because the radiation exposure is 10 times more the it is on the land.. there is 80% of ocean to explore and we can not go more then about 35,000 feet into the ocean which is not to the bottom of the ocean.. i do not know if those would help you but there are some info...
Information from ocean exploration can help us understand how we are affecting and being affected by changes in Earth's environment, including changes in weather and climate. Insights from ocean exploration can help us better understand and respond to earthquakes, tsunamis, and other hazards.
