Saline Lakes

2022
This chapter aims at introducing to saline lakes, which are defined by a salinity ≥ 3.0‰. Saline lakes are distributed from ice-covered regions to hot deserts, from the lowest point on earth's surface to altitudes of more than 4500 m. They are land-locked water bodies and show a broad range of chemical composition, salinity and biodiversity.

THE SALINE LAKES OF SASKATCHEWAN

Canadian Journal of Research, 1944
Sixty lakes in central and southern Saskatchewan were investigated during the years 1938 to 1943. Most of these are saline and lie within the aspen parkland. A few freshwater lakes from the adjacent forest zone were included for comparison. Physical and chemical studies included observation of depth, temperature, dissolved oxygen, light penetration ...

Chinese saline lakes

Hydrobiologia, 1993
China has many saline lakes. Most occur in the west and north-east. Four main regions can be distinguished: Qinghai-Tibet Plateau, North western, North-central and Eastern. All types of chemical composition occur, but some regionalization of types is found. The Palaeolimnology of many saline lakes in China has been investigated, and a variety of dating

Lake grevelingen: From an estuary to a saline lake. An introduction

Netherlands Journal of Sea Research, 1984
Abstract In 1972 an ecosystem study was started, mainly aiming at an analysis of the cycle of organic matter in the new evolving saline Lake Grevelingen, a former estuary, closed for reasons of flood prevention in 1971. The changing environmental conditions have been described. Nitrogen and silica apparently limit phytoplankton primary production.

Geochemistry of Saline Lakes

2003
Saline lakes are important environmental features in continental basins worldwide. They are critical for water and mineral resources, economic activity, and paleoenvironmental studies. Water and solute sources for saline lake brines are direct precipitation, surface flow, local or regional meteoric groundwaters, interstitial water of sediments, or deep

Saline Lakes and Saltpans

2016
There are several reasons why lakes are (or become) saline. Evidence lies in lagoons along open oceans where seawater may percolate through sandy barriers and lakes become saline or brackish, occasionally transforming their character. Further inland, saline lakes accumulate salt content by freshwater inflow and river discharge that carries minimal ...

Fallout Plutonium in an Alkaline, Saline Lake

Science, 1980
Plutonium isotopes, derived from global fallout following atmospheric testing of nuclear weapons, have been measured in the water and sediments of a natural alkaline, saline lake. The activities of fallout plutonium in the water column are about two orders of magnitude greater than in most freshwater lakes, where these nuclides are found predominantly ...
