Submarine groundwater discharge (SGD) is now recognized as an important process of the
hydrological cycle worldwide and plays a major role as a conveyor of dissolved compounds …

Integrative concepts of the biosphere, ecosystem, biogeocenosis and, recently, Earth's
critical zone embrace scientific disciplines that link matter, energy and organisms in a …

The present-day 238U/235U ratio has fundamental implications for uranium-lead
geochronology and cosmochronology. A value of 137.88 has previously been considered …

Groundwater has long been an active area of research driven by its importance both as a
societal resource and as a component in the global hydrological cycle. Key issues in …

This paper represents the first reports on the natural and anthropogenic radionuclides in
Kestanbol granitic pluton and surrounding rocks, and coastal region of the Ezine town. To …

We review and synthesize the geologic record that constrains the sources of sea level rise
and freshwater discharge to the global oceans associated with retreat of ice sheets during …

There is increasing evidence indicating that syndepositional redistribution of sediment on
the seafloor by bottom currents is common and can significantly affect sediment mass …

The geochemistry of marine sediments is a major source of information about the past
environment. Of the many measurements that provide such information, those of the U …

Oxygen concentration defines the chemical structure of Earth's ecosystems while it also fuels
the metabolism of aerobic organisms. As different aerobes have different oxygen …

Uranium isotope ratios are widely utilized in paleoceanography. The 238 U/235 U ratio
(expressed as δ 238 U) is leveraged as a proxy for the areal extent of anoxic seafloor, and …
