Isotopes In The Estuary: Conception And Application Of Stable And Radioactive Carbon, Derek Detweiler
Isotopes In The Estuary: Conception And Application Of Stable And Radioactive Carbon, Derek Detweiler
Reports
Grades: 9-12 Subjects: Chemistry | Environmental Science | Oceanography
In this interactive estuary-focused activity, students will examine stable and radioactive isotope data which provide information about the source and age of environmental samples such as plant and soil matter. Students will calculate average isotope ratios from five reference land types (forest, wetland, agriculture, industry, aquatic) and an unknown site within an estuary. Students will graph their calculated ratios and determine the land type that most impacts their estuary based on reference-to-unknown comparisons.
