; a cloud of sediment that occurs when heavy rains or floods wash large amounts of sediment into the ocean. Visible from the air, apparent in satellite images and CTD data. Sewer System

; a report giving information on beach contamination status and often recommending action to be taken Algae

; A bloom, or rapid growth, of phytoplankton in the upper layers of the ocean, often due to an influx of nutrients, such as a sediment plume or seasonal upwelling. Area

; prokaryotic unicellular round, spiral, or rod-shaped single-celled microorganisms that live in soil, water, organic matter, or the bodies of plants and animals (singular bacterium.) Best Management Practice

; The uppermost spreading branchy layer of vegetation. Catch Basin

; An ocean process that occurs most notably on the western coasts of continents when cold nutrient rich bottom water flows to the surface along the continental coastlines. Upwelling is strong in California and Chile where it is closely linked to the fishing industry. Coastal upwelling is greatly reduced during El Niño events. Coliform Ba [..]

; A stream that is smaller than a river and larger than a brook.. CTD

; reservoir designed to slow the rate of flow in an open drainage facility. Dinoflagellates

; Dissolved Oxygen is important to the health of aquatic ecosystems. All aquatic animals need oxygen to survive. Natural waters with consistently high dissolved oxygen levels are most likely healthy and stable environments, and are capable of supporting a diversity of aquatic organisms. Natural and human-induced changes to the aquatic environment c [..]

; body of water at the lower end of a river which is connected to the ocean and semi-enclosed by land. In an estuary, sea water is measurably diluted by freshwater from the land. Eutrophication
