Volcanic related methylmercury poisoning as the possible driver of the end-Devonian Mass Extinction
The end-Devonian global Hangenberg event (359 Ma) is among the most devastating mass extinction events in Earth’s history, albeit not one of the “Big...

The Application of Sequence Stratigraphy to the Investigation and Remediation of LNAPL-Contaminated Sites
The heterogenous and complex nature of soil and groundwater systems leads to significant technical challenges in remediating Light Non-Aqueous Phase...

Climate-controlled submarine landslides on the Antarctic continental margin
Antarctica’s continental margins pose an unknown submarine landslide-generated tsunami risk to Southern Hemisphere populations and infrastructure....

Sustainable human population density in Western Europe between 560.000 and 360.000 years ago
The time period between 560 and 360 ka (MIS14 to MIS11) was critical for the evolution of the Neanderthal lineage and the appearance of Levallois...

The multicausal twilight of South American native mammalian predators (Metatheria, Sparassodonta)
Sparassodonts were the apex mammalian predators of South America throughout most of the Cenozoic, diversifying into a wide array of niches including...
-
Early Triassic ichthyopterygian fossils from the Russian Far East
Ichthyopterygia is a major clade of reptiles that colonized the ocean after the end-Permian mass extinction, with the oldest fossil records found in...
-
Impact of green clay authigenesis on element sequestration in marine settings
Retrograde clay mineral reactions (reverse weathering), including glauconite formation, are first-order controls on element sequestration in marine...
-
Large mass-independent sulphur isotope anomalies link stratospheric volcanism to the Late Ordovician mass extinction
Volcanic eruptions are thought to be a key driver of rapid climate perturbations over geological time, such as global cooling, global warming, and...
-
Thresholds of temperature change for mass extinctions
Climate change is a critical factor affecting biodiversity. However, the quantitative relationship between temperature change and extinction is...

Large-scale mass wasting in the western Indian Ocean constrains onset of East African rifting
Faulting and earthquakes occur extensively along the flanks of the East African Rift System, including an offshore branch in the western Indian...

Late quaternary biotic homogenization of North American mammalian faunas
Biotic homogenization—increasing similarity of species composition among ecological communities—has been linked to anthropogenic processes operating...
-
Lethal microbial blooms delayed freshwater ecosystem recovery following the end-Permian extinction
Harmful algal and bacterial blooms linked to deforestation, soil loss and global warming are increasingly frequent in lakes and rivers. We...

A Jurassic record encodes an analogous Dansgaard–Oeschger climate periodicity
Earth’s past climate exhibits short-term (1500-year) pronounced fluctuations during the last glacial period, called Dansgaard–Oeschger (DO) glacial...

Persistent high latitude amplification of the Pacific Ocean over the past 10 million years
While high latitude amplification is seen in modern observations, paleoclimate records, and climate modeling, better constraints on the magnitude and...

Event- and biostratigraphic evidence for two independent Ries and Steinheim asteroid impacts in the Middle Miocene
For decades, the Nördlinger Ries and Steinheim Basin in southern Germany have been regarded as a textbook example of a terrestrial impact crater...

A global synthesis of high-resolution stable isotope data from benthic foraminifera of the last deglaciation
We present the first version of the Ocean Circulation and Carbon Cycling (OC3) working group database, of oxygen and carbon stable isotope ratios...

Origination of the modern-style diversity gradient 15 million years ago
The latitudinal diversity gradient (LDG) is a prevalent feature of modern ecosystems across diverse clades
1 –4 . Recognized for well over a century,...

Persistent global marine euxinia in the early Silurian
The second pulse of the Late Ordovician mass extinction occurred around the Hirnantian-Rhuddanian boundary (~444 Ma) and has been correlated with...
-
Triton, a new species-level database of Cenozoic planktonic foraminiferal occurrences
Planktonic foraminifera are a major constituent of ocean floor sediments, and thus have one of the most complete fossil records of any organism....

Isolation of the South China Sea from the North Pacific Subtropical Gyre since the latest Miocene due to formation of the Luzon Strait
The North Pacific subtropical gyre (NPSG) plays a major role in present global ocean circulation. At times, the gyre has coursed through the South...
