Silt
I still consider myself to be a "newbie" at BHB diving, but it seems to me that there are at least three different types of "bottoms" out there. I've fashioned a "monopod" to screw into the bottom of my camera housing that has an old screwdriver for the part that I use as the "finger rest" on the "bottom".
In some areas, this "rest" actually just rests on the bottom surface substrate (rare). In the "broken shell" bottom areas, it sinks in a couple of inches and I can hold still even in moderate current and surge and even manage some decent video with a 60mm macro lens on the DSLR.
In some "sandy" bottom areas, the screwdriver sinks down a few more inches, but still eventually "grabs" and will help me remain relatively stable in current.
However, there are definitely areas where the "silt" on top of the sand is like nothing else I've ever divven around. My 14 inch "monopod" would bottom out without ever getting a purchase in this powdery stuff. AAMOF, I've had times where I was "skulling" with my hand for a little positioning maneuver from three or four feet off the bottom, and I stirred up a huge cloud of silt as if I had kicked the bottom with my fins.
Don't really know exactly how this might fit in with the current (pun intended) discussion, but I *do* enjoy stirring things up and muddying the waters (see above).
