How will these resources help you?

As with many aspects of the ocean, most of our understanding of how climate change affects it does not extend far beneath the surface. It is a cause for concern that changes in greenhouse gas concentration in the atmosphere are changing the nutrient dynamics of the water. However, the ocean also offers solutions to counteracting climate change. The hydrosphere is a complex system involving numerous cycles of nutrients. Iron enrichment of the ocean, for example, increases the productivity of phytoplankton which stimulates phytoplankton blooms, where carbon dioxide uptake from the atmosphere occurs at a much greater rate. This list aims to support teachers and older students in developing their understanding of these processes. The resources link well to the Carbon Cycles topic, which is a core area of A-level Geography.
