Is the International Seabed Authority Subject to ISA?

The United States does assert an exploration lease area for deep sea mining in the Clerian Clipperton zone. The International Seabed Authority more or less controls this, and as I understand it, they are in the process of coming up with rules. There is a little bit of tension that has been going on for decades over the fact that most countries on Earth have kind of agreed to participate in this international government structure.
