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.
