    Science On a Sphere
    Well-crafted visualizations provide unique and powerful teaching tools

    Science On a Sphere® is a large visualization system that uses computers and video projectors to display animated data onto the outside of a sphere. Researchers at NOAA developed Science On a Sphere® as an educational tool to help illustrate Earth System science to people of all ages. Animated images of complex processes such as ocean currents, sea level rise, and ocean acidification are used to to enhance the public's understanding of our dynamic environment.
    Ocean Acidification on Science On a Sphere®

    The movies below were developed for use on Science On a Sphere® and show computer model simulations of surface ocean pH and carbonate mineral saturation state for the years 1895 to 2094.

    The first movie shows a computer recreation of surface ocean pH from 1895 to the present, and it forecasts how ocean pH will drop even more between now and 2094. Dark gray dots show cold-water coral reefs. Medium gray dots show warm-water coral reefs. You can see that ocean acidification was slow at the beginning of the movie, but it speeds up as time goes on. This is because humans are releasing carbon dioxide faster than the atmosphere-ocean system can handle.

    Ocean Today Kiosk Online
    This website provides access to current and archived videos of the Ocean Today kiosk at the Sant Ocean Hall in the Smithsonian Institution's National Museum of Natural History. The Ocean Today Kiosk is a dynamic, visitor-friendly multi-media experience that illustrates both the ocean's influence on humans and their influence upon the ocean. The website offers a transcript of the video along with links for more information.

Coral Bleaching Lesson at Bridge Ocean Education Teacher Resource Center - 0 views

  •  
    Summary: Assess coral bleaching using water temperature data from the NOAA National Data Buoy Center.

    Objectives
    * Describe the relationship between corals and zooxanthellae.
    * Identify stresses to corals.
    * Explain coral bleaching and the processes that cause coral bleaching.
    * Examine water temperature data and compare to levels known to induce coral bleaching.
    * Predict the effects of prolonged, increased temperaturs on coral reefs.

    Introduction
    The magnificent beauty of a coral reef is a true masterpiece of Mother Nature. A reef is a sculpture of living organisms, varied in color, texture, shape, and size. The creation of these works of art takes many, many years (some reefs are thousands of years old), and they don't exist solely for show. Reefs are building blocks for rich communities, providing habitat for a myriad of organisms, and they are some of the most diverse ecosystems on the planet. In addition, they support fishing grounds, attract tourists, and protect shorelines from waves and storms. "

Coral Bleaching: A White Hot Problem (COSEE-NOW) - 0 views

  •  
    "Some of the planet's most beautiful and diverse ecosystems are at risk. With temperatures on the rise, coral reefs are at greater risk for coral bleaching. Using ocean observing system data from NOAA's National Data Buoy Center, this classroom activity examines ocean temperatures off Puerto Rico to see how coral reefs are being impacted and predict what's on the horizon. Brought to you by Sea Grant's Bridge website and COSEE-NOW.

    This activity was developed in response to the 2005 massive coral bleaching event in the Caribbean caused by high sea surface temperatures. Using ocean observing system data, water temperatures can be monitored to evaluate the likeliness of other bleaching events.

    Via the COSEE-NOW online community, we were able to receive valuable feedback on making the graph of water temperature more user-friendly and expanding the discussion questions to evoke some higher level thinking from students.

    This activity has been demonstrated to teachers at the National Marine Educators Association conference and Virginia Sea Grant professional development institutes; and to graduate students in several different settings.
