I work for an organization that uses equipment like this. We can't afford to buy or staff this scale of equipment, and the Canadian government (DFO in particular) might have the cash to purchase the equipment but nowhere near the staff. Sensor networks are a lot of work. The ocean likes to break stuff. You need to monitor nodes extensively. It requires a broad skill set, both physically and digitally, backed by a lot of knowledge and ideally experience. These people aren't very common, so building a team to support this network outside of the USA would not be trivial.

Maybe you could part it out to a number of orgs and governments, but I doubt the US government has much interest in putting in the labour to facilitate that. This entire project seems like it's designed to be offensive as it is to be anything else.

It's an enormous shame.
