[HTML][HTML] Uranium in natural waters and the environment: Distribution, speciation and impact
PL Smedley, DG Kinniburgh - Applied Geochemistry, 2023 - Elsevier
The concentrations of U in natural waters are usually low, being typically less than 4 μg/L in
river water, around 3.3 μg/L in open seawater, and usually less than 5 μg/L in groundwater …

Strong and deep Atlantic meridional overturning circulation during the last glacial cycle
Abstract Extreme, abrupt Northern Hemisphere climate oscillations during the last glacial
cycle (140,000 years ago to present) were modulated by changes in ocean circulation and …

North Atlantic ocean circulation and abrupt climate change during the last glaciation
The most recent ice age was characterized by rapid and hemispherically asynchronous
climate oscillations, whose origin remains unresolved. Variations in oceanic meridional heat …

Covariation of deep Southern Ocean oxygenation and atmospheric CO2 through the last ice age
No single mechanism can account for the full amplitude of past atmospheric carbon dioxide

Uranium isotopic compositions of the crust and ocean: Age corrections, U budget and global extent of modern anoxia
The 238 U/235 U isotopic composition of uranium in seawater can provide important insights
into the modern U budget of the oceans. Using the double spike technique and a new data …

Introduction to U-series geochemistry
During the last century, the Earth Sciences underwent two major revolutions in
understanding. The first was the recognition of the great antiquity of the Earth and the …

Increased dust deposition in the Pacific Southern Ocean during glacial periods
Dust deposition in the Southern Ocean constitutes a critical modulator of past global climate
variability, but how it has varied temporally and geographically is underdetermined. Here …

U-Th-Ra fractionation during weathering and river transport
The potential of radioactive disequilibria as tracers and chronometers of weathering
processes has been recognised since the 1960's (eg, Rosholt et al. 1966; Hansen and Stout …
