Maris Pacifici

Maris Pacifici 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 Maris Pacifici rather than just read about it. In short: Maris Pacifici, more accurately named the Descriptio Maris Pacifici ("Description of the Pacific Ocean"), was the first dedicated map of the Pacific to be printed. It is considered an important advancement in cartography.

Key takeaways

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

Reference excerpt

Maris Pacifici, more accurately named the Descriptio Maris Pacifici ("Description of the Pacific Ocean"), was the first dedicated map of the Pacific to be printed. It is considered an important advancement in cartography. This map was drawn by Abraham Ortelius in 1589, based upon a map of America from the same year that was drawn by Frans Hogenberg. Some details of the map may have been influenced by a 1568 description of Japan in a manuscript by Vaz Dourado, rather than a map, hence its peculiar shape. The landmass illustrated to the south of all of the Pacific and South America is a representation of Terra Australis.

Worked examples

Example 1 — a first encounter with Maris Pacifici

Start with the simplest possible case. Write down what Maris Pacifici 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 Maris Pacifici 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 Maris Pacifici 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 Maris Pacifici

In research: Maris Pacifici 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 Maris Pacifici 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: Maris Pacifici is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1589 in science, 1589 works, 16th-century maps and globes, so understanding it makes those chapters shorter.
In everyday life: Look for Maris Pacifici 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.
