Observe an animation that shows the role of the salt marsh as a filter [link]
| |
Salt marsh / filter/ pollutants |
|
Groundwaters flow into the salt marsh from the surrounding drainage area, marsh grasses and the surrounding peat extract excess pollutants and nutrients from it. |

| |
Type of estuary |
|
Animation shows rising waters flood a low-lying river valley, creating a coastal plain estuary. |

Type of estuary
|
|
Animation shows ocean waves moving sediments shoreward, as the sediments build up, they form sandbars. |

| View the distribution of blue crab in different salinity zones of an estuary during each stage of its life cycle. [link]
| |
Salinity/adaptation/blue crabs |
|
Blue crabs are mobile predators whose salinity requirements change at different stages in their lives. |

|
| View an animation of secci disk dissappearing in water due to turbidity. [link]
| |
Turbidity/monitoring
|
|
Turbidity is essentially a measurement of how cloudy or clear the water is, or, in other words, how easily light can be transmitted through it. The animation represents the idea that the cloudier the water, the greater the turbidity. |

| View an animation of a "parcel of water" as its pH changes from acidic to alkaline. [link]
| |
ph/monitoring
|
|
Knowledge of pH is important because most aquatic organisms are adapted to live in solutions with a pH between 5.0 and 9.0. This animation shows a "parcel of water" as the pH changes from acidic to alkaline. |

Examine this animation representing what happens when the concentration of microscopic green algae, and therefore chlorophyll, increases in a body of water. [link]
| |
Chlorophyll/monitoring
|
|
Chlorophyll is a green pigment in plants that turns light energy into food and allows plants to grow, and releases oxygen in a process called photosynthesis.This animation represents what happens when the concentration of microscopic green algae, and therefore chlorophyll, increases in a body of water. |
