Sharkwater

Sharkwater is a 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 Sharkwater rather than just read about it. In short: Sharkwater is a 2006 Canadian documentary film written and directed by Rob Stewart. Helping to protect sharks, changing government policy, and inspiring the creation of shark conservation groups, Sharkwater is considered one of conservation's success stories, resulting in shark finning being banned in over 90 countries.

Key takeaways

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

Reference excerpt

Sharkwater is a 2006 Canadian documentary film written and directed by Rob Stewart. Helping to protect sharks, changing government policy, and inspiring the creation of shark conservation groups, Sharkwater is considered one of conservation's success stories, resulting in shark finning being banned in over 90 countries. In the film, Stewart documents current attitudes about sharks, and how shark-hunting industries are driving them to extinction. Sharkwater explores the densest shark hunting populations in the world, exposing the exploitation and corruption of the shark-hunting industry in the marine reserves of Cocos Island, Costa Rica and the Galapagos Islands, Ecuador. Stewart travels with Paul Watson and his Sea Shepherd Conservation Society ship as they confront shark poachers in Guatemala and Costa Rica. Among the group's experiences are boat confrontations, poachers, police, corrupt court systems, and eventually murder charges. Also, Stewart states how the increasing demand for shark-fin soup in Asia is fuelling an illegal trade in sharks. His expedition is cut short, however, when he is diagnosed with necrotizing fasciitis, from which he recovers. Stewart discovers that sharks prevent the overconsumption of plankton by other fish, which moderates climate change. Yet sharks have gone from predator to prey, and while they have survived Earth's mass extinctions, they could be extinct within a few years. The film has received 31 international awards.

Sequel Stewart was working on a sequel film, Sharkwater Extinction, at the time of his death in January 2017. The film was completed by Team Sharkwater, and premiered at the 2018 Toronto International Film Festival in September. Rob Stewart's Parents, Brian and Sandy Stewart, said "[the] entire team stayed with it, everybody stepped up. We have people from all over the world — cinematographers, filmmakers, really important people — offering to help finish this, and that was really heartwarming."

Worked examples

Example 1 — a first encounter with Sharkwater

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

In research: Sharkwater appears in 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 Sharkwater 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: Sharkwater is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2006 Canadian films, 2006 English-language films, 2006 documentary films, so understanding it makes those chapters shorter.
In everyday life: Look for Sharkwater 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 Sharkwater in simple terms?

Why does Sharkwater matter?

Because it connects several science 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 Sharkwater?

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.
