d) The picture shows a red coral that lives down to a depth of max. 300 meters. How does a fish or a human perceive the coral at 50 meters deep or below - as red or black? Justify the answer.

Answer 1

2.a)

Advantages of using cameras:

1. Instantaneous Satisfaction
2. Film is Expensive to Buy and Process
3. Massive Storage Space for Photos
4. Multiple Functions
5. Video Camera
6. Easy to Share
7. Lighter or Built-in
8. Easy Editing
9. More Display Options
10. Home Printing

Advantages of using ROV:

Can work in any water depths.

- More abilites to perform mechanical, inspection and recording tasks.

Advantages of AUV:

• Excellent navigational algorithms for providing accurate target location.
• It has low deployment costs as it does not require bulky and complex support equipment.
• High reliability and improved data quality.
• It reduces operational errors and high costs associated in employing a human operator.
• It follows rough terrain easily with the optimal positioning of sensors.

Advantages of BUOYS

• buoys can see through clouds. Well, not really, but many satellite sensors can not, which is why you often see large white areas in SST imagery. Worse yet, when a large storm, like a hurricane, happens to move through an area, it can block the view from satellites for several days.
