|Actually the DSV (Deep Submergence Vehicle) does not belong to me. But the camera does. It was a small camera that I bought at Walmart and I was taking photos with it. When we were below the light penetration depth, barely into the trench, not at the bottom of the deepest part, a male (bull) whale came by looking at us with our lights on. He left the area before I recalled that I had a camera with me. Later I thought that this would be a nice picture. I wanted to know if there was any light at all at that depth and I tested this picutre and found it to be totally black. It is real. This is the Marianas Trench at night, near to the top of the trench.
Again, this is not all the way down at the deepest part. My friends with the DSV said that they had never seen any whales that deep. Only the male whales go down to the trench and then they only go a little deeper, I do not remember how much more: maybe 1/2 mile or so. The US Navy knows how deep the whales go since the US Navy goes everywhere in the ocean, everywhere.
You guys have helped me a lot here. Maybe in a year or so when I go back, I might take some of you with me as long as there is room in the DSV. It is a big commercial DSV used by some deep sea platform builders that I used to supply water-proof concrete to. In case you wondered, regular concrete, here in the US, is not suited for this. The concrete that we sold to them was mixed with powdered volcanic ash which has tiny enough granules to make the concrete water-proof.
Although, as you seem to have suggested, this entire account with all of my information might be just some 14 year old kid making up stories on a much used computer, and when the neighbors come over after school we might laugh at how the adults fall for this stuff tell us secrets of how to program like a professional. Except for the part about my learning C and C++. I really am learning C and C++, or am I even doing that? You don't know.
