Coral bleaching is the process when corals become white due to loss of symbiotic algae and photosynthetic pigments. This loss of pigment can be caused by various stressors, such as changes in temperature, light, or nutrients. Bleaching occurs when coral polyps expel the zooxanthellae that live inside their tissue, causing the coral to turn white. The zooxanthellae are photosynthetic, and as the water temperature rises, they begin to produce reactive oxygen species. This is toxic to the coral, so the coral expels the zooxanthellae. Since the zooxanthellae produce the majority of coral colouration, the coral tissue becomes transparent, revealing the coral skeleton made of calcium carbonate. Most bleached corals appear bright white, but some are blue, yellow, or pink due to pigment proteins in the coral.
The Channel Islands National Marine Sanctuary is a sanctuary off the coast of Santa Barbara and Ventura counties in Southern California 350 miles south of San Francisco and 95 miles north of Los Angeles. It was designated in 1980 by the National Oceanic and Atmospheric Administration.
The National Estuarine Research Reserve System is a network of 30 protected areas established by partnerships between the National Oceanic and Atmospheric Administration (NOAA) and coastal states. The reserves represent different biogeographic regions of the United States. The National Estuarine Research Reserve System protects more than 1.3 million acres of coastal and estuarine habitats for long-term research, water-quality monitoring, education, and coastal stewardship.
The National Ocean Service (NOS) is an office within the U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA). It is the responsible for preserving and enhancing the nation's coastal resources and ecosystems along approximately 95,000 miles (153,000 km) of shoreline, that is bordering 3,500,000 square miles (9,100,000 km2) of coastal, Great Lakes, and ocean waters. Its mission is to "provide science-based solutions through collaborative partnerships to address the evolving economic, environmental, and social pressures on our oceans and coasts." The offices works with partnered agencies to ensure that the ocean and coastal areas are safe, healthy, and productive. Its projects focus on working to ensure the safe and efficient marine transportation, promoting the protection of coastal communities, conserving marine and coastal places. NOemploys 1,700 scientists, natural resource managers, and specialists in many different fields. The National Ocean Service was previously also known as the National Ocean Survey until it was renamed in 1983.
Marine protected areas (MPAs) are protected areas of the world's seas, oceans, estuaries or in the US, the Great Lakes. These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. In some situations, MPAs also provide revenue for countries, potentially equal to the income that they would have if they were to grant companies permissions to fish. The value of MPA to mobile species is unknown.
The Atlantic Oceanographic and Meteorological Laboratory (AOML), a federal research laboratory, is part of the National Oceanic and Atmospheric Administration's (NOAA) Office of Oceanic and Atmospheric Research (OAR), located in Miami in the United States. AOML's research spans tropical cyclone and hurricanes, coastal ecosystems, oceans and human health, climate studies, global carbon systems, and ocean observations. It is one of seven NOAA Research Laboratories (RLs).
Marine ecosystems are the largest of Earth's aquatic ecosystems and exist in waters that have a high salt content. These systems contrast with freshwater ecosystems, which have a lower salt content. Marine waters cover more than 70% of the surface of the Earth and account for more than 97% of Earth's water supply and 90% of habitable space on Earth. Seawater has an average salinity of 35 parts per thousand of water. Actual salinity varies among different marine ecosystems. Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many invertebrates live. The intertidal zone is the area between high and low tides. Other near-shore (neritic) zones can include mudflats, seagrass meadows, mangroves, rocky intertidal systems, salt marshes, coral reefs, lagoons. In the deep water, hydrothermal vents may occur where chemosynthetic sulfur bacteria form the base of the food web.
The National Marine Sanctuary of American Samoa is a federally-designated underwater area protected by the National Oceanic and Atmospheric Administration's (NOAA) Office of National Marine Sanctuaries. This sanctuary is the largest and most remote in the National Marine Sanctuary system. Spanning 13,581 sq mi, it is thought to be home to the greatest biodiversity of aquatic species of all themarine sanctuaries. Among them are expansive coral reefs, including some of the oldest Porites coral heads on earth, deep-water reefs, hydrothermal vent communities, and rare archeological resources. It was established in 1986, and then expanded and renamed in 2012.
The National Environmental Satellite, Data, and Information Service (NESDIS) was created by the National Oceanic and Atmospheric Administration (NOAA) to operate and manage the United States environmental satellite programs, and manage the data gathered by the National Weather Service and other government agencies and departments.
The Florida Department of Environmental Protection (FDEP) is the Florida government agency responsible for environmental protection.
The Joint Ocean Commission Initiative is a bipartisan, collaborative group in the United States that aims to "accelerate the pace of change that results in meaningful ocean policy reform." The Joint Initiative was established by the members of two major U.S.-based oceans commissions: the Pew Oceans Commission and the United States Commission on Ocean Policy. It was originally co-chaired by former White House Chief of Staff Leon Panetta and former Chief of Naval Operations Admiral James D. Watkins, chairs of the Pew and U.S. Ocean Commissions, respectively. Currently, the Joint Initiative is led by a Leadership Council, which is co-chaired by Christine Todd Whitman, former EPA Administrator under President George W. Bush and former governor of New Jersey, and Norman Y. Mineta, Secretary of Commerce under President Bill Clinton and Secretary of Transportation under President George W. Bush.
Earthwatch Institute is an international environmental charity. It was founded in 1971 as Educational Expeditions International by Bob Citron and Clarence Truesdale. Earthwatch Institute supports Ph.D. researchers internationally and conducts over 100,000 hours of research annually using the Citizen Science methodology. Earthwatch's mission statement states that the organization "connects people with scientists worldwide to conduct environmental research and empowers them with the knowledge they need to conserve the planet." As such, it is one of the global underwriters of scientific field research in climate change, archaeology, paleontology, marine life, biodiversity, ecosystems and wildlife. For over fifty years, Earthwatch has raised funds to recruit individuals, students, teachers, and corporate fellows to participate in field research to understand nature's response to accelerating global change.
The Coral Triangle (CT) is a roughly triangular area in the tropical waters around the Philippines, Indonesia, Malaysia, Papua New Guinea, the Solomon Islands and Timor-Leste. This area contains at least 500 species of reef-building corals in each ecoregion. The Coral Triangle is located between the Pacific and Indian oceans and encompasses portions of two biogeographic regions: the Indonesian-Philippines Region, and the Far Southwestern Pacific Region. As one of eight major coral reef zones in the world, the Coral Triangle is recognized as a global centre of marine biodiversity and a global priority for conservation. Its biological resources make it a global hotspot of marine biodiversity. Known as the "Amazon of the seas", it covers 5.7 million square kilometres (2,200,000 sq mi) of ocean waters. It contains more than 76% of the world's shallow-water reef-building coral species, 37% of its reef fish species, 50% of its razor clam species, six out of seven of the world's sea turtle species, and the world's largest mangrove forest. In 2014, the Asian Development Bank (ADB) reported that the gross domestic product of the marine ecosystem in the Coral Triangle is roughly $1.2 trillion per year and provides food to over 120 million people. According to the Coral Triangle Knowledge Network, the region annually brings in about $3 billion in foreign exchange income from fisheries exports, and another $3 billion from coastal tourism revenues.
Coral reef protection is the process of modifying human activities to avoid damage to healthy coral reefs and to help damaged reefs recover. The key strategies used in reef protection include defining measurable goals and introducing active management and community involvement to reduce stressors that damage reef health. One management technique is to create Marine Protected Areas (MPAs) that directly limit human activities such as fishing.

The resilience of coral reefs is the biological ability of coral reefs to recover from natural and anthropogenic disturbances such as storms and bleaching episodes. Resilience refers to the ability of biological or social systems to overcome pressures and stresses by maintaining key functions through resisting or adapting to change. Reef resistance measures how well coral reefs tolerate changes in ocean chemistry, sea level, and sea surface temperature. Reef resistance and resilience are important factors in coral reef recovery from the effects of ocean acidification. Natural reef resilience can be used as a recovery model for coral reefs and an opportunity for management in marine protected areas (MPAs).

The Western Pacific Regional Fishery Management Council (WPRFMC) is one of eight regional councils established under the Magnuson-Stevens Fishery Conservation and Management Act (MSA) in 1976 to manage offshore fisheries. The WPRFMC's jurisdiction includes the US exclusive economic zone (EEZ) waters around the State of Hawaii; US Territories of American Samoa and Guam; the Commonwealth of the Northern Mariana Islands (CNMI); and the US Pacific remote island areas of Johnston, Midway, Palmyra and Wake Atolls; Baker, Howland and Jarvis Islands; and Kingman Reef. This area of nearly 1.5 million square miles is the size of the continental United States and constitutes about half of the entire US EEZ. It spans both sides of the equator and both sides of the dateline. The WPRFMC also manages domestic fisheries based in the US Pacific Islands that operate on the high seas.
The Coral Triangle Initiative on Coral Reefs, Fisheries, and Food Security (CTI-CFF), or the Coral Triangle Initiative (CTI), is a multilateral collaborative partnership among six countries. Partners work together to sustain living marine and coastal resources by addressing crucial issues such as food security, climate change, and marine biodiversity.
The Marine Policy of the Barack Obama administration comprises several significant environmental policy decisions for the oceans made during his two terms in office from 2009 to 2017. By executive action, US President Barack Obama increased fourfold the amount of protected marine space in waters under United States control, setting a major precedent for global ocean conservation. Using the U.S. president's authority under the Antiquities Act of 1906, he expanded to 200 nautical miles the seaward limits of Papahānaumokuākea Marine National Monument in Hawaiʻi and the Pacific Remote Islands Marine National Monument around the U.S. island possessions in the Central Pacific. In the Atlantic, Obama created the Northeast Canyons and Seamounts Marine National Monument, the first marine monument in the U.S. exclusive economic zone (EEZ) in the Atlantic.
