Barriers to FOCE export/adoption/use



Notes:

Barriers to FOCE export/adoption/use

- manufacturing capability
- underwater housings and connections
- programming capability (UI, embedded)
- power electronics (medium, high voltage, i.e. >100V)
- instrument calibration
- systems engineering (selecting power, processing and software components)
- what else?

- access to cabled observatory -> (see infrastructure)
- access to ships, ROVs for deployment, recovery, maintenance -> weight, portability, size, low power
- access to engr staff and facilities -> COTS, open source
- budget - > reduce dollar cost, more value for $, open source/free
- shore infrastructure (power, site access) -> low power, easy connection, stand-alone
- permitting -> environmentally friendliness
- language -> documentation, internationalization (UI, doc)

[deep foce]
- underwater mateable connectors
- Ti 4km housings
- 1 kw power
- software for data handling (SSDS)
- full control / experience of full process (mfg->)


Basic System Concepts (what to optimize)
- Minimize Dollar Cost
- All COTS
- All open source
- Stand-alone
- Lowest Power?


Elements of a concept design (technology pool)
	- CO2 source 
	- power source 
	- controller hardware 
	- controller software
	- UI software
	- telemetry link
	- thrusters/equiv
	- instruments (pH, CTD, current/flow, DO)
	- environmental sensors (temp, RH, water level, V,I)
	- cameras
	- data merging technologies (to allow customization)

	...
