Question 5

An oceanographic research agency is developing communications infrastructure for two new operations:

  1. Research Outpost X: Located on a remote volcanic island, this outpost must start transmitting basic environmental data immediately. Over the next 444 years, the site will be expanded into a permanent, fully-staffed science observatory requiring high-throughput data links.

  2. Exploration Vessel Y: A mobile survey ship that will map seabed geology across five different deep-ocean sectors during a temporary 121212-month mission.

Describe appropriate communication solutions for each of these two operations, focusing on the use of satellite communication networks and submarine fibre optic cabling.

In your response, you should:

a.

Outline the physical principles of how both communication technologies transmit data.

[8]
b.

Suggest and justify your communication solutions for both Research Outpost X (including both short-term and long-term phases) and Exploration Vessel Y.
