Key takeaways

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

Reference excerpt

Sylvia Alice Earle (born August 30, 1935) is an American marine biologist, oceanographer, explorer, writer, and lecturer. She has been a National Geographic Explorer at Large (formerly Explorer in Residence) since 1998. Earle was the first chief scientist of the U.S. National Oceanic and Atmospheric Administration, and was named by Time Magazine as its first Hero for the Planet in 1998. Earle is part of the group Ocean Elders, which is dedicated to protecting the ocean and its wildlife. Earle gained a large amount of publicity when she was featured in Seaspiracy (2021), a Netflix Original documentary by British filmmaker Ali Tabrizi. Earle eats a vegetarian diet. She describes the chemical build-up in carnivorous fish, the 90% depletion of populations of large fish, and references the health of oceans in her dietary decision. Also, she describes the seafood industry as "factory ships vacuuming up fish and everything else in their path. That's like using bulldozers to kill songbirds…". In a discussion at the Good Food Conference in California, Earle warns of disappearing fish stocks, and that while coastal people's diets have included seafood for centuries, the commercial fishing industry no longer makes sense. She encourages transitions to plant-based diets as a solution.

Early life and education Earle was born in 1935 in the Gibbstown section of Greenwich Township, Gloucester County, New Jersey, to Alice Freas (Richie) Earle and Lewis Reade Earle. Both her parents were enthusiastic about the outdoors and supportive of their daughter's early interests in the natural world. The family moved to Dunedin on the western coast of Florida during Earle's childhood. Earle received an associate degree from St. Petersburg Jr. College (1952), a Bachelor of Science degree from Florida State University (1955), a Master of Science (1956) and a Doctorate of Phycology (1966) from Duke University. Sylvia Earle's life work has been shaped directly by Rachel Carson, whose talent she rhapsodizes about in the Introduction to the 2018 edition of Carson's 1951 best-seller, The Sea Around Us. "Most remarkable to me is what she did imagine. Her writings are so sensitive to the feelings of fish, birds and other animals that she could put herself in their place, buoyed by the air or by water, gliding over and under the ocean's surface. She conveyed the sense that she was the living ocean…"

Career

Earle was a Radcliffe Institute Scholar (1967–1969) and a research fellow at Harvard University (1967–1981). After receiving her Ph.D. in 1966, she spent a year as a research fellow at Harvard, then returned to Florida as the resident director of the Cape Haze Marine Laboratory. Earle was a research associate at the University of California, Berkeley (1969–1981). In 1969, she applied to join the Tektite Project, an installation fifty feet below the surface of the sea off the coast of the Virgin Islands which allowed scientists to live submersed in their area of study for up to several weeks. Although she had logged more than 1,000 research hours underwater, Earle was rejected from the program. The next year, she was selected to lead the first all-female team of aquanauts in Tektite II. Earle was the Curator of Phycology at the California Academy of Sciences (1979–1986). In 1979, she made an open-ocean JIM suit dive, untethered, to the sea ocean floor near Oahu. She set the women's depth record of 381 metres (1,250 ft) which still holds to date. In 1979 she also began her tenure as the Curator of Phycology at the California Academy of Sciences, where she served until 1986. From 1980 to 1984, she served on the National Advisory Committee on Oceans and Atmosphere.

In 1982 she and her later husband, Graham Hawkes, an engineer and submersible designer, founded Deep Ocean Engineering to design, operate, support and consult on piloted and robotic subsea systems. In 1985, the Deep Ocean Engineering team designed and built the Deep Rover research submarine, which operates down to 1,000 metres (3,300 ft). By 1986, Deep Rover had been tested and Earle joined the team conducting training off Lee Stocking Island in the Bahamas. Earle left the company in 1990 to accept an appointment as Chief Scientist at the National Oceanic and Atmospheric Administration, where she stayed until 1992. She was the first woman to hold that position. During this post, given her expertise on the impact of oil spills, Earle was called upon to lead several research trips during the Persian Gulf War in 1991 to determine the environmental damage caused by Iraq's destruction of Kuwaiti oil wells. In 1992, Earle founded Deep Ocean Exploration and Research (DOER Marine) to further advance marine engineering. The company, now run by Earle's daughter Elizabeth, designs, builds, and operates equipment for deep-ocean environments. In 1998, Earle received the title National Geographic Explorer in Residence and now holds the title 'Explorer at Large'. She is sometimes called "Her Deepness" or "The Sturgeon General". From 1998 to 2002, she led the Sustainable Seas Expeditions, a five-year program sponsored by the National Geographic Society and funded by the Richard and Rhoda Goldman Fund to study the United States National Marine Sanctuary. During this time, Earle was a leader of the Sustainable Seas Expeditions, council chair for the Harte Research Institute for the Gulf of Mexico Studies at Texas A&M-Corpus Christi, and chair of the Advisory Council for the Ocean in Google Earth. She also provided the DeepWorker 2000 submersible used to quantify the species of fish as well as the space resources utilized within the Stellwagen Bank National Marine Sanctuary. In 2001, Earle received the National Parks Conservation Association's Robin W. Winks Award For Enhancing Public Understanding of National Parks. Earle founded Mission Blue (also known as the Sylvia Earle Alliance, Deep Search Foundation, and Deep Search) in 2009. In 2009, she also received the 100k TED prize which allowed her to continue her ocean advocacy work. Given her past experience with the Exxon Valdez and Mega Borg oil spills, Earle was called to consult during the Deepwater Horizon Disaster in the Gulf of Mexico in 2010. During this year she also gave a 14-minute speech in front of 3,500 delegates and United Nations ambassadors at The Hague International Model United Nations Conference.

Worked examples

Example 1 — a first encounter with Sylvia Earle

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

In research
Sylvia Earle appears in biology 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 Sylvia Earle 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
Sylvia Earle is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1935 births, 20th-century American biologists, 20th-century American earth scientists, so understanding it makes those chapters shorter.
In everyday life
Look for Sylvia Earle 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.
