National Marine Sanctuary

National Marine Sanctuary 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 National Marine Sanctuary rather than just read about it. In short: A U.S. National Marine Sanctuary is a federally designated area within United States waters that protects areas of the marine environment with special conservation, recreational, ecological, historical, cultural, archeological, scientific, educational, or aesthetic qualities.

Key takeaways

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

Reference excerpt

A U.S. National Marine Sanctuary is a federally designated area within United States waters that protects areas of the marine environment with special conservation, recreational, ecological, historical, cultural, archeological, scientific, educational, or aesthetic qualities. The program was established in 1972 by the Marine Protection, Research, and Sanctuaries Act and is currently administered by the National Ocean Service through the National Marine Sanctuaries Act (NMSA). While National Marine Sanctuaries are multiple-use areas, the NMSA emphasizes that one of the express purposes of a sanctuary is to "maintain the natural biological communities" and to "protect and, where appropriate, restore and enhance natural habitats, populations, and ecological processes." The National Marine Sanctuary System consists of 18 marine protected areas that encompass about 785,000 square miles (2,030,000 km2). Individual areas range from less than 1 to 583,000 square miles (3 to 1,509,963 km2). The Office of National Marine Sanctuaries (ONMS), a division of the National Oceanic and Atmospheric Administration (NOAA), administers the 17 national marine sanctuaries. The program began after the 1969 Santa Barbara oil spill off the coast of California brought the plight of marine ecosystems to national attention. The United States Congress responded in 1972 with the Marine Protection, Research and Sanctuaries Act which allowed for the creation of marine sanctuaries. The resources protected by U.S. national marine sanctuaries range from coral reef ecosystems in American Samoa, Florida, Hawaii, and Texas, to shipwrecks in the Great Lakes and the Atlantic Ocean. The NMSP also is involved in the administration of the Papahānaumokuākea Marine National Monument and the Rose Atoll Marine National Monument, although they are not U.S. national marine sanctuaries. The NMSP jointly administers the Papahānaumokuākea Marine National Monument in conjunction with the United States Fish and Wildlife Service and the State of Hawaii, and it jointly administers the Rose Atoll Marine National Monument with the U.S. Fish and Wildlife Service.

Scope of protection Designation as a National Marine Sanctuary does not automatically prohibit fishing and other activities. Recreational and commercial fishing is allowed in some sanctuaries. It is possible to restrict consumptive or destructive activities through the initial designation process and NMSP actions. There are restrictions in some sanctuaries that are enforced by other governing agencies. For example, current regulations restricting fishing in Stellwagen Bank were not issued by the NMSP, but rather by National Marine Fisheries Service (NOAA Fisheries) and the New England Fishery Management Council, which have jurisdiction in federal waters off the New England coast generally. The private nonprofit organization Marine Conservation Institute has compiled fact sheets for each sanctuary listing activities which are directly regulated by the NMSP.

Designating sanctuary sites Site selection is done under the auspices of the National Oceanic and Atmospheric Administration (NOAA). Regional teams of marine scientists identify geographically representative sites for potential marine sanctuaries. NOAA then selects candidate sites and meets with state or territorial resource managers and/or the state or territorial governor's staff to determine the local level of interest in establishing a sanctuary. If there is mutually satisfactory interest, the candidate sites are evaluated through a process of public and legislative review and validated by the United States Congress and state or territorial governments. NOAA initiates the designation by the preparation of a Draft Environmental Impact Statement (DEIS) and a proposed management plan, then publishes a notice of its plans in the Federal Register. NOAA sponsors regional meetings and public hearings to gather comments. The U.S. Congress receives the draft statements and may conduct its own hearings. NOAA prepares a Final Environmental Impact Statement (FEIS) that addresses the concerns raised in the DEIS process and distributes it for comment. Finally, upon approval of the President of the United States, the United States Secretary of Commerce, who oversees NOAA, designates the area as a National Marine Sanctuary. The U.S. Congress and the governor of the state or territory then may formally object to or appeal the designation.

Existing sancturies

NOTES: (1) The National Marine Sanctuary of American Samoa originally was named the Fagatelle Bay National Marine Sanctuary. (2) The Greater Farallones National Marine Sanctuary originally was named the Gulf of the Farallones National Marine Sanctuary.

Former sanctuaries

NOTE: These sanctuaries were subsumed by the Florida Keys National Marine Sanctuary on November 16, 1990, but continued to operate until July 1, 1997, when they were integrated into the Florida Keys sanctuary and redesignated as Existing Management Areas.

Worked examples

Example 1 — a first encounter with National Marine Sanctuary

Start with the simplest possible case. Write down what National Marine Sanctuary 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 National Marine Sanctuary 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 National Marine Sanctuary 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 National Marine Sanctuary

In research
National Marine Sanctuary 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 National Marine Sanctuary 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
National Marine Sanctuary is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coasts of the United States, Lists of protected areas of the United States, National Marine Sanctuaries of the United States, so understanding it makes those chapters shorter.
In everyday life
Look for National Marine Sanctuary 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.
