Evidence for salt diffusion from sediments contributing to increasing salinity in the Salton Sea, California

  title={Evidence for salt diffusion from sediments contributing to increasing salinity in the Salton Sea, California},
  author={George D. Wardlaw and David L. Valentine},
Geochemical investigations of interstitial waters from the Salton Sea, CA reveal evidence of concentrated brines in the sediments underlying the lake’s two basins. The brines are likely caused by the gradual dissolution of evaporite deposits. The chemical composition of the brine in the northern basin is dominated by magnesium and sulfate and differs from the southern basin where the dominant components are sodium and chloride. Sediment depth distributions of major ions and porosity indicate… 
Laboratory studies on the coprecipitation of phosphate with calcium carbonate in the Salton Sea, California
The Salton Sea is a hypereutrophic, saline lake in the desert of southern California. Like many lakes, the primary productivity of the Sea is limited by phosphorus. However, unlike most lakes, the
Biogeochemical investigations of marine methane seeps, Hydrate Ridge, Oregon
[1] A series of biogeochemical studies were conducted at the southern summit of Hydrate Ridge, offshore Oregon. Using the submersible DSV Alvin, sediment push cores were collected from two distinct
Origin of Salts and Brine Evolution of Bolivian and Chilean Salars
Central Andes in Bolivia and northern Chile contain numerous internal drainage basins occupied by saline lakes and salt crusts (salars). Salts in inflow waters stem from two origins: alteration of
Sulfide irruptions and gypsum blooms in the Salton Sea as detected by satellite imagery, 1979–2006
Abstract Bright pale-green surface waters, locally called “green tides,” are visible to the naked eye and satellite sensors in patches at the Salton Sea, usually between May and November. These were
Current Continental Base-Levels Below Sea Level, Located Close to the Sea
The structure, the geological history, and the hydrogeological configuration, common to most of the base levels included in this category, are the following The base-levels are currently
Decline of springtime abundance of the pileworm Neanthes succinea in relation to hydrographic conditions at the Salton Sea, California
The Salton Sea is the largest lake in California, and its most abundant macroinvertebrate is the pileworm, which is a major dietary item for three of the four most abundant fish species in the lake, and for at least one waterbird.
Archaeal and Bacterial Communities Respond Differently to Environmental Gradients in Anoxic Sediments of a California Hypersaline Lake, the Salton Sea
The differential response of archaeal and bacterial communities to salinity and carbon patterns is consistent with the hypothesis that adaptations to energy stress and availability distinguish the ecologies of these domains.


Chemical evolution of the Salton Sea, California: nutrient and selenium dynamics
The Salton Sea is a 1000-km2 terminal lake located in the desert area of southeastern California. This saline (∼44 000 mg l−1 dissolved solids) lake started as fresh water in 1905–07 by accidental
The relation between pore water chemistry and benthic fluxes of nutrients and manganese in Narragansett Bay, Rhode Island
Ahs tract Benthic fluxes of dissolved nutrients and manganese from biologically disturbed, relatively unpolluted sediment in Narragansett Bay, Rhode Island, have been measured. Analyses of the
The diagenesis of phosphorus in a nearshore marine sediment
Diagenetic processes and nutrient fluxes at the sediment-water interface, northern Adriatic Sea, Italy
Early diagenetic processes that control pore-water chemistry and nutrient fluxes at the sediment-water interface were studied in late summer 1989 and spring 1990 at four sites influenced by fine
Limnology, Sedimentation, and Microorganisms of the Salton Sea, California
The Salton Sea, originally a fresh-water lake formed by the flood of the Colorado River in 1905, is located in the center of the Colorado Desert of California. By 1929, the water of the lake had
Chemical and physical characteristics of the Salton Sea, California
A 1-year sampling program was conducted to assess current chemical and physical conditions in the Salton Sea. Analyses included general physical conditions and a suite of water quality parameters,
Thermal, mixing, and oxygen regimes of the Salton Sea, California, 1997–1999
The Salton Sea is a shallow (mean depth = 8 m; maximum depth = 15 m), saline (41–45 g l−1), intermittently mixing, 57 km long, 980 km2 lake located in the arid southwestern United States. The Sea is
Characteristics and contaminants of the Salton Sea sediments
One of the most significant findings of this study was the absence of elevated concentrations of organic chemicals commonly used in agriculture earlier this century, such as dichlorodiphenyltrichloroethane (DDT).
Geochemical Processes: Water and Sediment Environments
The approach of this book to geochemistry can be summarized in the question: What happens, and how fast does it happen, when waters, solids, and gases interact in the earths surface environment? The
The benthic invertebrates of the Salton Sea: distribution and seasonal dynamics
The rocky shoreline habitat is highly productive, and is an important refuge during periods of seasonal anoxia for Neanthes and for the other invertebrates that also serve as prey for fish and birds.
