New Study Reveals Shocking Depths of Deep-Sea Exploration
A groundbreaking study published in Science Advances reveals that humans have explored less than 0.001% of the earth’s deep-seafloor, equating to an area roughly the size of Rhode Island. Despite advancements in sonar mapping, true visual exploration beyond 200 meters remains limited due to extreme darkness and cold. Katy Croff Bell, lead researcher and veteran deep-sea explorer, initiated the study to quantify what’s been seen, uncovering records of over 43,000 deep-sea expeditions since 1958, mostly within close proximity to the U.S., Japan, and New Zealand.
The findings highlight the significant gaps in our understanding of global deep-sea ecosystems, particularly in underexplored regions like the Indian Ocean. Deep-sea experts emphasize the revolutionary nature of past discoveries, which challenge existing scientific theories. Jeffrey Karson from Syracuse University expressed surprise at the minuscule area of deep-sea explored thus far.
To enhance deep-ocean exploration, marine biologist Jon Copley advocates for the development of cost-effective technologies that can democratize access to the oceans. Copley believes that revisiting known sites over time is as essential as exploring new depths. As we uncover the mysteries of our oceans, the potential for new, transformative discoveries remains vast and largely untapped.
