Condition Reports


The Office of National Marine Sanctuary Condition Reports provide a summary of resources in each sanctuary, pressures on those resources, the current condition and trends, and management responses to the pressures that threaten the integrity of the marine environment. Specifically, the reports include information on the status and trends of water quality, habitat, living resources and maritime archaeological resources and the human activities that affect them.

National Marine Sanctuary System
2013 Condition Report

In the National Marine Sanctuary System Condition Report the status and trends of resource condition are evaluated across the system. Among the many pressures on the natural and archaeological resources in the system, a number stand out: marine debris entanglement, trapping and ingestion, loss of biodiversity, wildlife disturbance, ship strikes and water quality, to name a few. In the face of these pressures, sanctuaries are making important strides in resource protection through progressive, science-based management, targeted resource protection programs and engaging education and outreach activities.

Channel Islands 2016 Condition Report

In 2019, a new Channel Islands National Marine Sanctuary Condition Report was released. This marks a second comprehensive update to describe the status and trends of sanctuary resources including water quality, habitat, living resources, and maritime archaeological resources. In addition, this new condition report includes the status and trends of ecosystem services including food supply-commercial fishing; consumptive recreation-recreational fishing; non-consumptive recreation-wildlife viewing, SCUBA diving, snorkeling, and boating; sense of place-passive economic use value; maritime heritage; education; and science. The Ecosystem Services section of this report also includes a detailed explanation of Chumash history connected to the northern Channel Islands and surrounding sanctuary waters, as well as an introduction to ongoing Chumash community values, traditional knowledge and practices, and historical trauma.

Cordell Bank 2009 Condition Report

Cordell Bank National Marine Sanctuary is an extremely productive marine area off the west coast of United States in northern California. With its southern-most boundary located 42 miles (68 km) north of San Francisco, the sanctuary is entirely offshore, with the eastern boundary six miles from shore and the western boundary 30 miles (48 km) offshore at the 1000 fathom (1829 m) depth contour.

Fagatele Bay 2007 Condition Report

Fagatele Bay National Marine Sanctuary is an isolated national marine sanctuary contained within a small, flooded volcanic crater on the southern coast of Tutuila, American Samoa. The site is uniquely rich in both natural resources and cultural heritage. Fagatele Bay and its fringing coral reef have experienced severe disruptions from cyclones, crown-of-thorns starfish outbreaks, and more recently from coral bleaching and diseases (the causes of these are not fully understood).


Florida Keys 2011 Condition Report

Florida Keys National Marine Sanctuary is one of the largest marine protected areas in the United States, encompassing 2,896 square nautical miles (9,933 square kilometers). It was designated by Congress and exists under federal law, and became effective in state waters with the consent of the state of Florida.

Flower Garden Banks 2008 Condition Report

Located in the northwestern Gulf of Mexico, Flower Garden Banks National Marine Sanctuary includes three separate areas, known as East Flower Garden, West Flower Garden and Stetson Banks. The banks range in depth from 55 to nearly 500 feet.


Gray's Reef 2008 Condition Report

Gray's Reef National Marine Sanctuary protects particularly dense and nearshore patches of productive “live-bottom habitat” that are sparsely distributed from Cape Hatteras, N.C., to Cape Canaveral, Fla., on the inner- and mid-shelf of the South Atlantic Bight.

Gulf of the Farallones
2010 Condition Report

Located off the Central California coast and encompassing 966 square nautical miles, Gulf of the Farallones National Marine Sanctuary protects a diversity of highly productive marine habitats and supports an abundance of species. It is a complex system of bays, estuaries, mudflats, marsh and intertidal, coastal and oceanic waters, and is influenced by the highly urbanized San Francisco Bay area populated by nearly 8 million people.


Hawaiian Islands Humpback Whale
2010 Condition Report

Hawaiian Islands Humpback Whale National Marine Sanctuary is currently a single-species sanctuary whose primary mission is the protection of humpback whales and their habitat in the main Hawaiian Islands. Each winter, the sanctuary is home to more than half of the North Pacific humpback whale population. The sanctuary works with community members and agency representatives to protect one of the most important humpback whale breeding calving, and nursing grounds in the world.

Monitor 2008 Condition Report

In an effort to preserve one of the most famous shipwrecks in U.S. history, the wreck of the USS Monitor was designated our first national marine sanctuary on Jan. 30, 1975. The sanctuary comprises a column of water one nautical mile in diameter extending from the ocean’s surface to the seabed around the wreck of the Civil War ironclad, which lies 16 miles south-southeast of Cape Hatteras, N.C.


Monterey Bay 2015 Condition Report Partial Update: A New Assessment of the State of the Sanctuary Resources

In 2015 the Monterey Bay National Marine Sanctuary Condition Report was partially updated. The 2009 Monterey Bay condition report provided a summary of resources in the sanctuary, pressures on those resources, current conditions and trends, and management responses to reduce or mitigate human pressures. The 2015 report provides an update to the State of the Sanctuary Resources section, which assesses the health of the sanctuary. Sanctuary staff, with input from regional scientific experts, re-evaluated status and trend ratings for 16 standardized questions. Each question was re-evaluated for accuracy and completeness, given new data sets, published literature and expert opinion that have become available since 2009. For most questions, new information and updated narratives are provided, and many include new status and trend ratings. Trend ratings are generally based on trends since 2009. This re-evaluation was completed for three sanctuary environments: (1.) estuarine, (2.) nearshore and (3.) offshore. A fourth environment, seamount, was evaluated for the first time in this update due to the addition of Davidson Seamount Management Zone to the sanctuary in November 2008.

Olympic Coast 2008 Condition Report

Designated in 1994, the sanctuary's mission is to protect the Olympic Coast's natural and cultural resources through responsible stewardship, to conduct and apply research to preserve the area's ecological integrity and maritime heritage, and to promote understanding through public outreach and education.


Papahānaumokuākea Marine National Monument 2020 State of the Monument Report

Papahānaumokuākea Marine National Monument is the single largest conservation area under the U.S. flag, encompassing an area of 582,578 square miles of the Pacific Ocean—an area larger than all the country's national parks combined. Home to the highly endangered Hawaiian monk seal, threatened green turtles, and many species found nowhere else on earth, the complex and highly productive marine ecosystems of the monument are significant contributors to the biological diversity of the ocean.

Stellwagen Bank 2020 Condition Report

In 2020, a new Stellwagen Bank National Marine Sanctuary Condition Report was released. This marks a second comprehensive update to describe the status and trends of sanctuary resources including water quality, habitat, living resources, and maritime archaeological resources. In addition, this new condition report includes the status and trends of ecosystem services including heritage, food supply, consumptive and non-consumptive recreation, sense of place, science and education. This condition report will inform the next sanctuary management plan update process which will begin in 2020.


Thunder Bay 2013 Condition Report

Designated in 2000, Thunder Bay National Marine Sanctuary protects a nationally significant collection of historic shipwrecks and related maritime cultural resources in northern Lake Huron. Through research, resource protection and education, the sanctuary works to ensure that these important historic, archaeological and recreational sites are preserved for current and future generations.
