Kairei vent field

Kairei vent field 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 Kairei vent field rather than just read about it. In short: The Kairei vent field is a hydrothermal vent field located in the Indian Ocean at a depth of 2,460 metres (8,070 ft). It is just north of the Rodrigues triple junction, approximately 2,200 kilometres (1,400 mi) east from Madagascar.

Key takeaways

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

Reference excerpt

The Kairei vent field is a hydrothermal vent field located in the Indian Ocean at a depth of 2,460 metres (8,070 ft). It is just north of the Rodrigues triple junction, approximately 2,200 kilometres (1,400 mi) east from Madagascar. It is the first hydrothermal field discovered in the Indian Ocean and the first of the series of known vents along the Central Indian Ridge.

History The vent field was discovered in 2000 by the R/V Kairei and ROV Kaikō operated by Japan Marine Science and Technology Center (JAMSTEC). In 2001, the site was surveyed with high resolution prior to the deployment of ROV JASON. The vent field was visited again by JAMSTEC in 2009 on the YK09-13 cruise, where the HOV Shinkai6500 was deployed.

Geology The field is dominated by sulfide talus, with the approximate area of high-temperature venting constrained to approximately 40 square meters. Fluids from the vent field have been measured in excess of 360 °C (680 °F) and are rich in metals, providing a black-smoker appearance. Elevated chlorinity in venting fluids suggests that phase-separation happens deep below the field.

Biology The Kairei vent field is one of the few known locations of the Sea Pangolin, threatened by deep sea mining. It is also a site associated with Gigantopelta aegis and Alviniconcha strummeri gastropods. It is the site of discovery of Rimicaris kairei, belonging to the family of hydrothermal shrimp found at many sites in the Atlantic Ocean. Carbon and nitrogen isotopes suggest that there are four distinct trophic levels at the Karei vent field. Kairei is also of concern with respect to research on deep sea dispersal pathways, with some shared biological communities to those neighboring vent fields (Edmond, Solitaire, DoDo).

Worked examples

Example 1 — a first encounter with Kairei vent field

Start with the simplest possible case. Write down what Kairei vent field 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 Kairei vent field 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 Kairei vent field 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 Kairei vent field

In research: Kairei vent field 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 Kairei vent field 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: Kairei vent field is common in secondary-school and first-year university syllabi. It links to neighbouring topics Hydrothermal vents, Indian Ocean, Volcanism of the Indian Ocean, so understanding it makes those chapters shorter.
In everyday life: Look for Kairei vent field 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.
