Exploring the Uncharted Depths: The Vast Unknown of the Deep Seafloor

Researchers have reported that just 0.001 percent of the deep seafloor has been explored, prompting marine scientists to advocate for more research to understand this vital ecosystem as discussions about seabed mining continue.

In a groundbreaking study published in the journal Science Advances, researchers found that humans have visually documented just around 1,470 square miles, or approximately 0.001 percent, of the deep seafloor, an area slightly larger than the state of Rhode Island. This revelation comes as countries assess the possibility of industrial mining on the seabed to extract crucial minerals.

Led by marine biologist Katy Croff Bell, who is also the founder of the nonprofit Ocean Discovery League, the research underlines the urgent need for more information about the unexplored depths of our oceans. Bell argues that given our current lack of understanding of the deep sea, extensive research must precede any extraction activities.

"More information is always beneficial, so we can make more informed and better decisions," Bell stated. She emphasized the importance of studying the deep sea in understanding the ramifications of climate change and human actions on oceanic ecosystems. The allure of deep-sea exploration also captivates many marine scientists, with Bell noting, "You can just imagine what’s in the rest of the 99.999 percent."

The history of deep-sea visual documentation began with the U.S. Navy's submersible Trieste in 1958 and continued with the Alvin submersible in 1960. These pioneering explorations have enabled scientists to discover new species and observe vital interactions within marine environments, contributing significant knowledge about ocean ecosystems.
