Rosemary Bank

Rosemary Bank 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 Rosemary Bank rather than just read about it. In short: Rosemary Bank is a seamount approximately 120 kilometres (75 mi) west of Scotland, located in the Rockall Trough, in the northeast Atlantic. It was discovered in 1930 by the survey vessel HMS Rosemary, from which it takes its name.

Key takeaways

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

Reference excerpt

Rosemary Bank is a seamount approximately 120 kilometres (75 mi) west of Scotland, located in the Rockall Trough, in the northeast Atlantic. It was discovered in 1930 by the survey vessel HMS Rosemary, from which it takes its name. It is one of only three seamounts known in Scottish waters, along with the Anton Dohrn Seamount and Hebrides Terrace Seamount. Rosemary Bank hosts a range of important habitats including deep sea sponge aggregations and cold water coral. Many species of fish, including orange roughy, blue ling, leafscale gulper shark and Portuguese dogfish are also found here. In 2014 the bank was declared a Nature Conservation Marine Protected Area (NCMPA) in order to protect the sponge aggregs and the cenozoic marine geomorphology of the seabed. In 2020 it was replaced by the West of Scotland Marine Protected Area, which covers a much larger area. The feature originated about 70 million years ago, as a result of volcanic activity. Rosemary Bank rises to approximately 1,000 metres (3,300 ft) above the sea floor, its highest point being 400 metres (1,300 ft) below sea-level. Around its base lies a narrow "moat", where the sea-bottom is up to 300 m (980 ft) lower than the surrounding terrain. The lowest parts of these area are approximately 2,300 metres (7,500 ft) below sea level.

Worked examples

Example 1 — a first encounter with Rosemary Bank

Start with the simplest possible case. Write down what Rosemary Bank 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 Rosemary Bank 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 Rosemary Bank 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 Rosemary Bank

In research: Rosemary Bank 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 Rosemary Bank 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: Rosemary Bank is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cretaceous volcanoes, Marine geography stubs, Seamounts of the Atlantic Ocean, so understanding it makes those chapters shorter.
In everyday life: Look for Rosemary Bank 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.
