Muirfield Seamount

Muirfield Seamount 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 Muirfield Seamount rather than just read about it. In short: The Muirfield Seamount is a submarine mountain located in the Indian Ocean approximately 130 kilometres (70 nautical miles) southwest of the Cocos (Keeling) Islands. The Cocos Islands are an Australian territory, and therefore the Muirfield Seamount is within Australia's exclusive economic zone.

Key takeaways

Muirfield Seamount 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 Muirfield Seamount to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Muirfield Seamount from memory before moving on to harder problems.

Reference excerpt

The Muirfield Seamount is a submarine mountain located in the Indian Ocean approximately 130 kilometres (70 nautical miles) southwest of the Cocos (Keeling) Islands. The Cocos Islands are an Australian territory, and therefore the Muirfield Seamount is within Australia's exclusive economic zone. It is a submerged archipelago, approximately 2.5 kilometres (1.6 miles) in diameter and 16–18 metres (52–59 feet) below the surface of the sea. A 1999 biological survey of the seamount performed by the Australian Commonwealth Scientific and Industrial Research revealed that the area is depauperate. The Muirfield Seamount was discovered accidentally in 1973. The cargo ship MV Muirfield (a merchant vessel named after Muirfield, Scotland) was underway in waters charted at a depth of greater than 5,000 metres (16,000 ft), when she suddenly struck an unknown object, resulting in extensive damage to her keel. In 1983, HMAS Moresby, an Australian naval survey ship, surveyed the area where Muirfield was damaged, and charted in detail this previously unsuspected hazard to navigation. The accidental discovery of the Muirfield Seamount is often cited as an example of limitations in the vertical datum accuracy of some offshore areas as represented on nautical charts, especially on small-scale charts. More recently, in 2005 the submarine USS San Francisco (SSN-711) ran into an uncharted seamount about 560 kilometers (350 statute miles) south of Guam, sustaining serious damage and killing one seaman.

Worked examples

Example 1 — a first encounter with Muirfield Seamount

Start with the simplest possible case. Write down what Muirfield Seamount 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 Muirfield Seamount 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 Muirfield Seamount 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 Muirfield Seamount

In research: Muirfield Seamount 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 Muirfield Seamount 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: Muirfield Seamount is common in secondary-school and first-year university syllabi. It links to neighbouring topics Former islands from the last glacial maximum, Physical oceanography, Seamounts of the Indian Ocean, so understanding it makes those chapters shorter.
In everyday life: Look for Muirfield Seamount 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.
