Gondwana-1

Gondwana-1 is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Gondwana-1 rather than just read about it. In short: Gondwana-1 is a submarine communications cable network connecting New Caledonia and Australia brought into service in mid-2008. The cable landing points are: Narrabeen beach, Sydney, New South Wales, Australia Ouémo peninsula, Nouméa, New Caledonia And a second cable from Poindimié commune, North Province, New Caledonia Mouli Island, Ouvea commune, Loyalty Islands Province, New Caledonia Xepenehe, Lifou commune, Loy…

Key takeaways

Gondwana-1 belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Gondwana-1 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Gondwana-1 from memory before moving on to harder problems.

Reference excerpt

Gondwana-1 is a submarine communications cable network connecting New Caledonia and Australia brought into service in mid-2008. The cable landing points are:

Narrabeen beach, Sydney, New South Wales, Australia Ouémo peninsula, Nouméa, New Caledonia And a second cable from

Poindimié commune, North Province, New Caledonia Mouli Island, Ouvea commune, Loyalty Islands Province, New Caledonia Xepenehe, Lifou commune, Loyalty Islands Province, New Caledonia The Australian end of the Cable was terminated in mid November 2007 by the Cable Ship Ile de Re completing the laying of the cable. The fibre optic cable is laid in the Northern Sydney Protection Zone and comes ashore at Narrabeen beach where the Southern Cross Cable and Australia-Japan Cable are also laid. The system was officially brought into service in September 2008. Gondwana drastically boosted the capacity of the New Caledonia international gateway and decreased the latency to reach Australia and Western Europe, previously handicapped by a 700 ms round trip delay between Australian and Caledonian satellite teleport. It offers the second fibre access point in South Pacific islands after Fijian access to Southern Cross cable, commissioned in 2001. The fibre optic cable is a two-part system, firstly linking New Caledonia to Australia (and then on to the world via the existing Australian fibre optic cables) and a short unrepeated cable from New Caledonia to the Loyalty Islands, with a landing stations at Poindimie (Main island), Mouly (Ouvea) and Xepenehe (Lifou). The need for the cable was the increasing demand for advanced telecommunications such as broadband and due to the high cost of satellite bandwidth.

Worked examples

Example 1 — a first encounter with Gondwana-1

Start with the simplest possible case. Write down what Gondwana-1 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Gondwana-1 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Gondwana-1 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Gondwana-1

In research: Gondwana-1 appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Gondwana-1 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Gondwana-1 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2008 establishments in Australia, 2008 establishments in New Caledonia, Australia–France relations, so understanding it makes those chapters shorter.
In everyday life: Look for Gondwana-1 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Gondwana-1 matter?

Because it connects several earth science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Gondwana-1?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
