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.
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)
