As Deep As 377 Feet
Unless you have the earnings to support your urge for deep-sea exploration, then you won’t have close contact with whatever’s underwater. The Golden Gate strait’s deepest point is reportedly 377 feet, and the NOAA wanted to see what could be hiding in its depths.
It would be hazardous for humans to dive that deep because you can’t get any assurance that it will be 100% safe. It’s why people invest in different devices, in this case, robots, to explore the ocean floor. They were able to find reliable robots that got as deep as they needed.
