Viewers will dive into the Chesapeake Bay with Philippe Cousteau and team to learn how a 'dead zone' forms and investigate one of the most ecologically important Bay inhabitants, the Eastern Oyster.
Scientist and students explain the criteria used to judge the health of the marine environment. How strong is the population of the keystone species? Is the dissolved oxygen sufficient to check the growth of algae and accompanying bacteria? What does the animal population reveal about the number of species and their age range?
In identifying the criteria for a healthy marine environment, What is a Dead Zone may serve as an introduction to a study of the nature and health of marine environments; human - environment interactions; mmanaging resources; or sustaining ecosystems. These are themes found in Science, Geography, and Social Studies curricula.
Other videos provided by EarthEcho Expeditions - How to Measure Dissolved Oxygen; How to Measure Turbidity; How to Measure Nitrates and Phosphates - allow students to investigate in greater detail the criteria for a healthy marine system.
