Reference excerpt

Rachel Haymon is a marine geologist known for her work linking geological and biological processes occurring at deep-sea hydrothermal vents. In 2005 she was elected a fellow of the Geological Society of America.

Education and career As a child growing up in Baton Rouge Louisiana, Marie Curie was the only woman scientist Haymon knew. Haymon had multiple ideas about careers as a child, including several scientific options such as oceanographer, archeologist, astronaut. or paleontologist. In college, she decided to study geology and has a B.A. from Rice University (1976). In 1982, she earned her Ph.D. from the University of California, San Diego working on hydrothermal deposits at 21°N on the East Pacific Rise. Following her Ph.D., she accepted a position at the University of California, Santa Barbara where she was promoted to professor in 1998. Haymon retired from full professor in 2010.

Research Haymon's research centers on the deposition of minerals at deep-sea hydrothermal vents. Haymon's work on ophiolites in Oman revealed fossils of hydrothermal vent worms and geological evidence of hydrothermal venting. As a graduate student, Haymon worked on the mineralogy of hydrothermal vents at 21ºN North along the East Pacific Rise using samples collected during the RISE project. Using data from 1989, Haymon mapped the distribution of hydrothermal vents along the 9ºNorth of the East Pacific Rise. Then, in 1991, Haymon led the team that returned to this site and discovered a recent eruption on the seafloor. They dubbed the area "Tube Worm Barbecue" because of the dead tubes worms found in the regions with recent lava flow. Haymon described the excitement of seeing the outcome of the recent eruption in a subsequent newspaper article. Repeated visits to the area revealed the tube worms were gone within eleven months after the eruption, replaced by small fish, octopus, and crabs. Later work by Haymon on the East Pacific Rise revealed hydrothermal venting along the ridge-flank sites, away from the black smokers. In 2006, Haymon led the team that discovered the first black smokers within the hydrothermal vents fields near the Galapagos.

Worked examples

Example 1 — a first encounter with Rachel Haymon

Start with the simplest possible case. Write down what Rachel Haymon 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 Rachel Haymon 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 Rachel Haymon 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 Rachel Haymon

In research: Rachel Haymon 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 Rachel Haymon 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: Rachel Haymon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1953 births, 21st-century American women, American geologists, so understanding it makes those chapters shorter.
In everyday life: Look for Rachel Haymon 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.
