Hess called this process Sea-Floor Spreading. WebEvidence for Seafloor Spreading Much like Wegener before him, Hess ran into considerable resistance to his hypothesis by other geologists. There was little data from the ocean floor that could support his current hypothesis. Knowing that he still needed more data to convince the scientific community, Hess continued to work on his research.
