Question

Quizplus · Accepted Answer

Coring devices are the best choice for taking samples from the deep sea floor because they can extract sediment and rock cores from the seabed, which can provide information about the geological and biological history of the ocean floor. Echo sounders, seismic profilers, and remote sensing are techniques used for mapping and studying the ocean floor, but they do not allow for physical sampling of the seabed.
