Ocean Acidification Describes a Change in Chemistry
Read ocean acidification as a change in seawater chemistry and pH, while distinguishing a long-term process from one local measurement.
Follow the connections between rivers, shorelines and the open ocean.

Read ocean acidification as a change in seawater chemistry and pH, while distinguishing a long-term process from one local measurement.

Describe a visible transition between coastal surfaces without assuming that a sharp line on a map marks an equally sharp ecological boundary.

Read a coastal environment headline by finding the location, time span and measured quantity before extending its conclusion to another shoreline.

Understand why the mix of fresh and salt water varies across an estuary and why a salinity reading needs a place and time.

Check a habitat map’s legend, date, scale and survey limits before treating every coloured boundary as a precise line on the shore.

Where rivers meet the sea, changing water conditions support distinctive habitats. Start reading an estuary as a connected landscape.
