Welcome to the Olympic Coast National Marine 
Sanctuary web site. Here you'll discover the marine life and extraordinary habitats 
that make up this sanctuary and our continuing efforts to conserve 
these ocean and coastal treasures.

In order to understand and protect Olympic Coast National Marine Sanctuary for future generations, we use science to study this complex ecosystem. The ocean is very dynamic, making it hard to know what changes are natural versus man-made. It is a vast, interrelated system of physical, chemical and biological processes. And the technical challenges of studying the underwater environment make research very costly and difficult, especially in a remote place like the Olympic coast. Hence the need to conduct collaborative research with our resource partners.

We conduct scientific research in Olympic Coast National Marine Sanctuary for three important reasons:

  • to survey to know what's there (baseline data),
  • to detect trends, improvements or declines in important resources or changes that are part of larger global processes and
  • to give us the scientific basis for making important conservation decisions. Our research program includes all of these missions.

The (ROPOS) vehicle operates remotely to reach ocean depths of up to 16,404 feet.
To define the science and information needs necessary to address priority management issues, we have created a set of science needs documents. These documents are available at on the Office of National Marine Sanctuaries website, where you can find more background on the purpose, structure, and content of the system-wide science needs assessment.

Since only a fraction of the sanctuary has been mapped in detail, we conduct seafloor habitat mapping to understand relationships of biological communities to physical habitat.

Cold-water corals live without sunlight where water temperatures are 39-59° F.
Based on these maps, we and our partners survey and explore the seafloor habitats, documenting deep-sea coral and sponge communities, including fish, and finding submerged cultural resources such as shipwrecks or ancient habitations. Deep-sea exploration can make important contributions to resource protection by providing scientific information for management decisions.

Our oceanography program uses nearshore scientific moorings to monitor water chemistry and currents for investigations into climate change (e.g., ocean acidification) and hypoxia events as well as other related research to help understand and determine their impacts on the sanctuary.

The complete list of animals and plants occupying the seas has never been, and may never be totally known. From microscopic organisms that drift unseen in the currents, to the largest whales, the marine life of the Olympic Coast National Marine Sanctuary reminds us that humans share our ocean planet with other inhabitants.

And there are almost 90 species of marine birds that residents or transients, which range from shorebirds to high-seas albatrosses. Monitoring wide-ranging marine wildlife requires working with many resource partners using different survey platforms, such as boats, ships, and aircraft.

Hours that you spend working to improve marine habitats, understand trends in marine wildlife and share knowledge with others show your generosity to future generations.

All of these research programs are helping us to better understand ecosystem processes which are the ultimate challenges to marine conservation science. It requires a wide range of disciplines and the coordination of many subject-area experts.

If you would like to know more about what type of research surveys we participate in you can go to our survey/cruise summaries for more information. We also have information on our research vessel the R/V Tatoosh and other research assets at Olympic Coast National Marine Sanctuary.
