Intertidal zonation is the occurrence of animals and seaweeds on certain sections of a shoreline based on their ability to tolerate the factors within the intertidal zone. Some of the factors include large fluctuations in temperature, periods of drying when the tide is out, and large changes in salinity due to evaporation and freshwater input.
A common field study conducted by students while at the Huntsman is collecting data to determine intertidal zonation patterns. Students use transect lines, quadrats and meter sticks to gather data from the high tide to low tide mark. After gathering the data students create a graph which helps them to interpret the data and determine the different zones on the shoreline and what species inhabit each zone. Students then present their data to Huntsman staff, their teachers, and fellow students as a final activity.
The zonation field study allows students a taste of research science by allowing them to collect, interpret and present their own results. Check out our website for information on how to give our students this experience www.huntsmanmarine.ca/html/education.html.
