- Quiz
- The answers imply
- Therefore, observations of the ocean is very challenging.
- How do you observe the ocean?
- Platform, where you make observation
- Observation platform
- Ordinary platforms for ocean sciences
- Ordinary platforms:research ships
- A CTD observation on a research ships
- Ordinary platforms:voluntary observing ships or ship-of-opportunity (non-research ships)
- XBT observation lines and a voluntary ship
- Ordinary platforms:mooring buoys
- A surface mooring
- Ordinary platforms:satellites
- Non of ordinary platforms are suitable for basin-wide monitoring under-water conditions.
