Ocean Acidification and Oysters Lab

This classroom/laboratory activity allows students to understand how marine organisms may be affected by increased ocean acidification caused by climate change. Students explore and analyze the relationship between the growth of oyster larvae and the chemistry of ocean water by using data from the Whiskey Creek Hatchery in Oregon, USA.

Variations climatiques et composition isotopique de l’oxyène (O18_16 (Oxygène))

The tool allows a student to learn about the isotopes of oxygen (O18 and O16); to understand the relative distribution of these isotopes in the atmosphere, ocean and cryosphere; and to explore how these isotopes can be used as indicators of paleoclimate.
