Tenmarks Technical Requirements Information


Marine Ecosystem - an ecosystem in salt water. Examples include coral reefs, kelp forests, and polar oceans.

Freshwater Ecosystem - rivers, lakes, streams, ponds and wetlands. They have a much lower salt content than marine ecosystems.

Estuary - where freshwater meets saltwater, usually at the mouth of a river.  The water is described as brackish.  

Wetland - an area of land that is either permanently or seasonally saturated with water.  They filter pollutants and help prevent flooding.

Watershed - an area of land that captures rainfall and other precipitation and funnels it to a lake or stream or wetland.

Point Source Pollution - pollution that comes from a single, identifiable source.  An example would be a factory dumping waste into a river.

Non Point Source Pollution - pollution that comes from many different sources.  Often this pollution is picked up by runoff and carried into rivers and lakes.  

Macroinvertebrate - an organism without a backbone that can be seen without a microscope.  

Indicator Species - an organism whose presence, absence or abundance gives information about the condition of an ecosystem.  

Runoff - precipitation that is not absorbed by land, travels over the land surface to enter streams, rivers, lakes and storm drains

River Source - the original point from which a river flows.  Can be a glacier, spring, marsh, or lake.  

River Mouth - where a river enters a larger body of water. Sediment is deposited here.

Tributary - A stream or a river that flows into a larger stream or river

Groundwater -water found underground, filling the spaces between rocks and soil particles.  It is stored in underground formations called aquifers.  

Bonus Vocabulary

Eutrophication- the enrichment of water with nutrients, usually phosphorus and nitrogen, which stimulates the growth of algal blooms and rooted aquatic vegetation

Riparian Area - areas of plants and trees that grow along the edges of rivers, streams and lakes.  Can help prevent erosion and serve as filters for pollution.

Algal blooms - a rapid increase in the amount of algae in an aquatic ecosystem

Impervious - does not allow liquid to pass through

Pervious - allows liquid to pass through, permeable

Turbidity - the measure of cloudiness of water (measure of suspended particulate matter in the water, important for water quality testing)
