Lazarev Sea

Lazarev Sea 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 Lazarev Sea rather than just read about it. In short: The Lazarev Sea (Russian: Море Лазарева, More Lazareva) is a proposed name for a marginal sea of the Southern Ocean. It would be bordered by two proposals from a 2002 International Hydrographic Organization (IHO) draft, a King Haakon VII Sea to the west and a Riiser-Larsen Sea to the east, or between the Prime Meridian of 0° and 14°E.

Key takeaways

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

Reference excerpt

The Lazarev Sea (Russian: Море Лазарева, More Lazareva) is a proposed name for a marginal sea of the Southern Ocean. It would be bordered by two proposals from a 2002 International Hydrographic Organization (IHO) draft, a King Haakon VII Sea to the west and a Riiser-Larsen Sea to the east, or between the Prime Meridian of 0° and 14°E. It would stretch over an area of 929,000 km2 (359,000 sq mi).

History The Lazarev Sea was named in 1962 by the Soviet Antarctic Expedition in memory of Russian admiral Mikhail Lazarev (1788–1851), who discovered the Antarctic mainland with Fabian Gottlieb von Bellingshausen in 1820. The 2002 IHO draft was never approved by the IHO (or any other organization), and the 1953 IHO document (which does not contain this name) remains currently in force. Leading geographic authorities and atlases do not use the name, including the 2014 10th edition World Atlas from National Geographic Society and the 2014 12th edition of the Times Atlas of the World. But Soviet and Russian-state maps do.

Physical geography The prevailing depth of waters in the Lazarev Sea is 3,000 m (9,800 ft), and the maximum depth exceeds 4,500 m (14,800 ft). It stretches over an area of 929,000 km2 (359,000 sq mi). To the south of the Lazarev Sea lies Princess Astrid Coast of Queen Maud Land. The Lazarev Sea is a continental margin affected by multiple rifting episodes accompanied with transient volcanism. The Lazarev sea is also known to be very poor in sediment.

Worked examples

Example 1 — a first encounter with Lazarev Sea

Start with the simplest possible case. Write down what Lazarev Sea 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 Lazarev Sea 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 Lazarev Sea 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 Lazarev Sea

In research: Lazarev Sea 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 Lazarev Sea 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: Lazarev Sea is common in secondary-school and first-year university syllabi. It links to neighbouring topics Antarctic region, Lazarev Sea, Marine geography stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Lazarev Sea 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.
