The NOAA Office of National Marine Sanctuaries' video collection features different topics including resilience to changing ocean conditions. These short videos bring the challenges facing sanctuaries to life, and highlight what sanctuaries, individuals, and communities can do to build their resilience.

Changing Ocean Conditions in National Marine Sanctuaries

Explore how changing ocean conditions will affect marine sanctuaries in some of America's most spectacular places. More acidic waters will impact ecosystems, more frequent and harsher storms are damaging historic shipwrecks, coral reefs and kelp forests are stressed by warmer waters, and much more.

Pelagic Red Crabs

In early October, thousands of pelagic red crabs washed ashore in Monterey Bay National Marine Sanctuary. These crabs usually live offshore of Baja California, but warm waters, likely linked to El Niño, have transported them north. The last time these crabs washed ashore in the sanctuary was 1982-83, also an El Niño year. Watch our video to learn more!

Florida Keys National Marine Sanctuary Restoration Blueprint

The sanctuary will propose a Restoration Blueprint that embodies what we have learned from nearly 30 years of cutting-edge science, technical experience, and local community involvement.
