Autonomous underwater explorers will be used to gather large-scale ocean information is a FALSE statement.
Explanation:
In order to collect large-scale information on the oceans, using autonomous underwater explorers would not be a feasible option as the range of study that they would be able to carry out would be way too limited compared to what the government and the allied organizations could do by putting to use large equipment like submarines and other machines.
Also, the data collected by autonomous explorers would have to be authenticated in some or the other way. That would probably take another study in the same discipline because there would be no other way to authenticate it.
