What is an Estuary? 2/18/19 where Freshwater meets ocean what controls estuary conditions? 3 segments: Lower, river meets sea Middle, mixing Upper, largely Freshwater. *Salt water creeps up the shore, this the zone of gravitational circulation. area is called Neap Tides vs Spring Tides Ovs ppt and ppm %% PSU particles There's a of Estuaries. Small amount of sediment coming in and out. Turbidity and Salinity Seem to have an inverse relationship. * 4 types of Estuaries: 1. Coastal plain, downed river valleys. 2. Fjords: deep w/ Anoxia @ bottom. 3. Bar built, shallow 4. Built by tectonic process. * Estuaries categorized by tidal prism. The difference between high and low tide Micro, Meso, Macro, Hyper-tidal categories. Characteristics: •Geologically young and epnemeral. • Two-layered system of fresh and salt. Tidal prism is small for Neap and Large For Spring Our lagoon has water coming from Arroyo Colorado Le Not From the Mississippi.. * Estuaries can give a various amount/type of Sediment Anaerobic bacteria produce H₂5 during decomposition of OM The Oxygen comes from atmospheric diffusion and photosynim DO is removed by aerobic aerobic respiration, diffusion or/and Primary Production has multiple sources not all present e one time.
