State officials have gone so far as to build levees across major saltwater in-flows in times of especially severe drought. [7] Saltwater intrusion is temporarily stemmed in spring months when snow melt and rain runoff increase water volumes carried by the San Joaquin and Sacramento rivers, fending off saltwater intrusion.
The resulting back-surge in water flow is expected to force X2 into the Delta, jeopardizing spatially oriented habitat (like freshwater marshes), channelizing the low salinity zone, and threatening southern California's water supply, with unknown and unforeseeable consequences for the natural and human ecology of the West coast's largest estuary.
Suisun Marsh, 116,000 acres (470 km 2) of land, bays, and sloughs, is one of the largest estuarine marshes in the western United States. Geologically, the Suisun Marsh is the product of water-borne sediment deposition, carried from the Sacramento and San Joaquin Rivers into the San Francisco Bay.
The salinity in isolated bodies of water can be considerably greater still – about ten times higher in the case of the Dead Sea. Historically, several salinity scales were used to approximate the absolute salinity of seawater. A popular scale was the "Practical Salinity Scale" where salinity was measured in "practical salinity units (PSU)".
The tables below present an example of an artificial seawater (35.00‰ of salinity) preparation devised by Kester, Duedall, Connors and Pytkowicz (1967). [1] The recipe consists of two lists of mineral salts, the first of anhydrous salts that can be weighed out, the second of hydrous salts that should be added to the artificial seawater as a solution.
The California coastal salt marshes are vital ecosystems. To best preserve and restore them, research on microbial communities and sediment has been conducted. In a research study [ 3 ] done by the Pacific Estuarine Ecosystem Indicators Research Consortium in 2006, they investigated the effects of environmental factors and pollutants on the ...

A Coastal Discovery Center is located across California State Route 1 (the Pacific Coast Highway) from the Hearst Castle visitor center in San Simeon, California, near the William Randolph Hearst Memorial State Beach. [6] The Monterey Bay Marine Sanctuary Exploration Center opened on July 23, 2012 [7] at 35 Pacific Avenue in Santa Cruz, California.
