Where is an estuary found?
What are the normal temperatures for an estuary? Quiz By Catherine and Alexis Seagrass http://water.epa.gov/type/oceb/nep/about.cfm Sources Mangroves By: Airiel Fauna Cordgrass Ozzie Mozzies By: Eve Holley Salt meadows Is the only flowering plant in New Zealand capable of living in sea water. Seagrass is small and dark green, with ribbon-like leaves, this plant takes root in sandy silts on tidal flats throughout the country. It forms extensive meadows that spread from just above the low-tide level to full submersion in 1 to 2 metres of sea water Seagrass New Zealand’s native mosquitoes are irritating pests, but they do not transmit diseases to humans. In 1998 an Australian mosquito – the southern marsh mosquito – was found breeding near Napier. Subsequently it has been found in estuaries from Kaipara Harbour in the north to the Wairau Lagoon in the South Island. Adult females are aggressive biters and in Australia carry the Ross River virus. Humans infected with the virus may develop flu-like symptoms that last for months. The New Zealand government has spent $40 million to eradicate this unwanted visitor. Estuary food webs begin with the conversion of the sun’s energy to food energy by plants and plankton. Simplified feeding relationships are shown in this diagram.There are two main feeding pathways. One begins with large plants such as mangroves, seagrass and rushes. When they die their leaves and roots are broken down by bacteria and fungi to become detritus. Detritus is eaten by small animals such as snails, worms and shellfish and they, in turn, are eaten by larger creatures such as fish and birds. A second pathway begins with microscopic phytoplankton. They are eaten by tiny zooplankton which then become food for snails and shellfish. An estuary is the area on the coast where a freshwater body of water meets a saltwater body of water. Saltwater marshes are an example of this. Long Island is a great example, but most estuaries are found in New Zealand. About 300 estuaries can be found on New Zealand's coast! http://www.teara.govt.nz/en/diagram/4620/estuary-food-web
The climate of an Estuary can range from 20 to 70 degree Fahrenheit, And 20 degrees Celsius. The average rainfall per year is 100 to 800mm, but some places can reach 3,2000 mm in odd years
Some estuaries have four seasons Autumn, Spring, Winter, and Summer. For example the Mississippi river has four seasons, and is 25 degrees Celsius in the dry season and 18 degrees Celsius in the wet season. http://wiki.answers.com/Q/Where_are_estuaries_found http://www.answers.com/topic/estuary http://wiki.answers.com/Q/What_is_the_nearest_estuary_in_New_Zealand Cockles Mud Worms Crabs Ozzie Mozzies Diagram
