RV Investigator

RV Investigator is a mathematics 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 RV Investigator rather than just read about it. In short: RV Investigator is an Australian marine research vessel owned by the CSIRO and operated by its Marine National Facility, undertaking oceanographic, geoscience, ecosystem and fisheries research. In May 2009 the Government of Australia allocated $120 million for a new ocean-going research vessel to replace the 1972 built RV Southern Surveyor, which has served as the principal research ship for Australia's Marine Natio…

Key takeaways

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

Reference excerpt

RV Investigator is an Australian marine research vessel owned by the CSIRO and operated by its Marine National Facility, undertaking oceanographic, geoscience, ecosystem and fisheries research. In May 2009 the Government of Australia allocated $120 million for a new ocean-going research vessel to replace the 1972 built RV Southern Surveyor, which has served as the principal research ship for Australia's Marine National Facility since 1988. RV Investigator was designed by RALion (joint venture between Robert Allan Limited and Alion Science & Technology) and constructed in Singapore. It was transferred from Sembawang Shipyard to the delivery crew on 5 August 2014 for pre-departure testing and setup. The vessel arrived at its home port of Hobart on 9 September 2014 and was officially launched on 12 December 2014.

Specifications The RV Investigator is able to accommodate up to 40 scientists, go to sea for up to 60 days at a time and spend up to 300 days of the year at sea on research voyages. Operating costs are estimated to be $140,000 per day. Special features of the ship are a "gondola", similar to a winged keel, mounted 1.2 m below the hull, and two drop keels (which can be lowered to a maximum of 4m below the hull), to carry scientific instruments below the layer of microbubbles created by the movement of the ship’s hull through the water. Such instrumentation includes acoustic mappers, a pelagic sediment profiler to produce maps of the sea floor, and 2 Acoustic Doppler current profilers. The hull and the machinery of the ship have been designed to operate as quietly as possible to enhance its scientific capabilities.

Notable works In November 2020, the RV Investigator front camera captured a green meteor entering the atmosphere and produced a clear video of this rare phenomenon. The meteor footage was captured off the southern coast of Tasmania.

Worked examples

Example 1 — a first encounter with RV Investigator

Start with the simplest possible case. Write down what RV Investigator claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, 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 RV Investigator 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 RV Investigator 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 RV Investigator

In research: RV Investigator appears in mathematics 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 RV Investigator 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: RV Investigator is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2013 ships, CSIRO, IMO numbers, so understanding it makes those chapters shorter.
In everyday life: Look for RV Investigator 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.

Frequently asked questions

What is RV Investigator in simple terms?

Why does RV Investigator matter?

Because it connects several mathematics 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 RV Investigator?

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.
