Changing ocean conditions are threatening America’s physical, social, economic, and environmental well-being. National marine sanctuaries and monuments must contend with rising water temperatures and sea levels, water that is more acidic and contains less oxygen, shifting species, and altered weather patterns and storms. While all of our sanctuaries and monuments must face these global challenges, each is affected differently. Click on the images below to explore how each sanctuary and monument is being, and is projected to be, affected by changing ocean conditions.
Information contained in the below profiles reflects the state of the science as of the date of publication (listed on the cover). Our understanding of changing ocean conditions and their impacts can change as new science is conducted.
