  • Primary Topic: Marine Protected Areas (MPAs).

Classification of Marine Protected Areas (IUCN Categories)

Category I.a: Marine Reserve

  • Definition: An area where any removal of resources is strictly prohibited.

  • Exceptions: There are occasionally small exceptions made for aboriginal or artisanal uses, provided they are low impact.

  • Core Objective: To conserve "outstanding" ecosystems. These are defined as areas that are currently more-or-less natural and pristine, exhibiting little influence from human activities.

  • Management Requirements: These areas should not require intensive ongoing efforts to achieve conservation objectives because the ecosystem is already in a natural state.

  • Case Study Example:   - Channel Islands National Marine Sanctuary: Located near the Channel Islands, this site serves as a representative example of a Marine Reserve.

Category I.b: Marine Wilderness Area

  • Definition: An area predominantly oriented toward protecting and conserving the "ecological integrity of natural areas."

  • Historical Milestone: The first marine wilderness area was established in 2012 off the Point Reyes National Seashore specifically to protect oyster beds.

  • Infrastructure Restrictions: The area must be free of modern infrastructure, including but not limited to:   - Roads.   - Dams.   - Pipelines.   - Oil and gas platforms.   - Any other permanent structures.

  • Geographic Context for Point Reyes:   - Location: Marin County.   - Proximity: Near San Francisco and Oakland.

Category II: Marine National Park

  • Definition: Areas that may allow limited fishing or recreational activities within restricted locations.

  • Dual Objectives:   1. To protect "biodiversity."   2. To promote "education and recreation."

  • Ecosystem State: The area should have a relatively intact ecosystem.

  • Management Approach: May require varying degrees of management to maintain a successful balance between public use and natural ecology.

  • Case Study Example:   - Hallyeohaesang National Park, South Korea: Located across areas including the West Sea, South Sea, and East Sea.   - Specific Locations Mentioned: Gyeongnam, Sacheon, Gamam, Neukdo, Geoje, Dala, Odongdo, Sangju, Bijindo, Dapo Songdo, and Somaemuldo.   - Coordinates Referenced: Between 33extoN33^ ext{o}\text{N} and 37extoN37^ ext{o}\text{N}, and around 128.02extoE128.02^ ext{o}\text{E}, 128.20extoE128.20^ ext{o}\text{E}, and 128.40extoE128.40^ ext{o}\text{E}.

Category III: Marine National Monument

  • Definition: Protected areas focused on historic sites, such as shipwrecks, or cultural sites.

  • Primary Objective: To protect an "outstanding natural feature" and the habitat surrounding it.

  • Scope of Protection: Protection is centered around a specific feature, such as a unique geologic formation or specific water features (e.g., spray zones or eddies).

  • Case Study Example:   - Blue Hole National Monument, Belize: Located within the Lighthouse Reef Atoll in the Caribbean Sea.   - Associated Dive Sites and Locations: Sandbore Caye, Northern Two Cayes, West Point I & II, The Great Blue Hole, Southwest Cut, The Aquarium, Silver Caves, Cathedral Reef, Que Brada, Long Caye Ridge, Tres Cocos, Hat Caye Drop-off, Hat Caye, Eagle Ray Wall, Nurse Shark Lodge, Long Caye, Half Moon Wall, and Half Moon Caye.

Category IV: Marine Habitat/Species Management Area

  • Definition: An area where the removal of resources is allowed, but only under somewhat strict management controls.

  • Focus: The primary management focus is on specific species in conjunction with their habitat.

  • Priority Criteria: Preference is given to the protection of species that possess unique cultural, historical, economic, or ecological significance.

  • Case Study Example:   - South Ari Atoll, Maldives: Located in the Indian Ocean, southwest of India and Sri Lanka.

Category V: Protected Seascape

  • Definition: Coastal areas (including land) of pristine value for scenic or other cultural reasons, with management aimed at maintaining overall use.

  • Associations: These areas are often associated with unique geologic formations or unusual (endemic) assemblages of species.

  • Case Study Example:   - Apo Island, Philippines: Located within the Coral Triangle in the Pacific Ocean.

Category VI: Sustainable Use of Natural Resources

  • Definition: A category encompassing a wide variety of management schemes, ranging from heavy to very limited management.

  • Core Objective: To manage and sustain ecologically and economically important resources in instances where conservation efforts benefit both.

  • Philosophy: Focuses on preserving natural resources based on sustainable harvesting for future generations. It is implemented when management is deemed necessary to preserve critical cultural or economic ways of life.

  • Case Study Example:   - Menai Bay Conservation Area, Zanzibar, Tanzania.   - Related Conservation Areas in the Region: Tumbatu Conservation Area, Mnemba-Chwaka Bay Conservation Area, Stone Town Heritage Site, Changuu-Bawe Conservation Area, and Chumbe Island Sanctuary.

U.S. National Marine Sanctuary System

Statutory Framework

  • Legal Definition: The term "marine sanctuary" is not an official IUCN category. It is a specific designation used by the United States.

  • Legislation: Established under the Marine Protection, Research, and Sanctuaries Act of 1972.

  • Status: Currently, there are 16 marine sanctuaries in U.S. waters. Although they use the U.S. nomenclature, all have some level of formal IUCN recognition.

Designated and Proposed Sites

  • West Coast and Pacific:   - Olympic Coast   - Greater Farallones   - Cordell Bank   - Monterey Bay   - Chumash Heritage   - Channel Islands   - Papahānaumokuākea   - Hawaiian Islands Humpback Whale   - Pacific Remote Islands   - American Samoa (U.S.) / Rose Atoll

  • Great Lakes and Interior:   - Thunder Bay   - Lake Ontario (Proposed)   - Wisconsin Shipwreck Coast   - Lake Erie Quadrangle (Proposed)

  • East Coast and Atlantic:   - Stellwagen Bank   - Hudson Canyon (Proposed)   - Mallows Bay-Potomac River   - Monitor   - Gray's Reef   - Florida Keys

  • Gulf of Mexico:   - Flower Garden Banks

Bathymetric and Mapping Data

  • Resource: NOAA's Office of National Marine Sanctuaries customized the GEBCO world map for site identification.

  • Depth Measurements: Bathymetric tints on mapping correspond to corrected meters below mean sea level.

  • Scale Increments: Visual maps track depths at intervals of 200200, 500500, 10001000, 20002000, 30003000, 40004000, 50005000, 60006000, and 7000 meters7000\text{ meters}.
