In recent decades, the land-ocean aquatic continuum, commonly defined as the interface, or
transition zone, between terrestrial ecosystems and the open ocean, has undergone …

This review focuses on the rapidly growing field of natural 238U/235U variability, largely
driven by the technical advances in the measurement of U isotope ratios by mass …

The emergence and diversification of early animals is commonly thought to have coincided
with atmosphere and ocean oxygenation across the terminal Neoproterozoic and early …

Oceanic Anoxic Event 2 (OAE 2), occurring∼ 94 million years ago, was one of the most
extreme carbon cycle and climatic perturbations of the Phanerozoic Eon. It was typified by a …

The isotopic compositions of redox-sensitive metals, including uranium (U), in marine
sediments have recently emerged as powerful diagnostic tracers of the redox state of the …

The appearance and radiation of animals are commonly attributed to Neoproterozoic
oceanic oxygenation, yet independent geochemical evidence for such an event remains …

Oxygenation of the early Cambrian ocean is commonly ascribed to high organic export to
the sediment due to the rise of algae and filter-feeding animals, but direct evidence of …

Sedimentary molybdenum (Mo) and uranium (U) abundances, as well as their isotope
systematics, are used to reconstruct the evolution of the oxygenation state of the surface …

Fjords have been identified as sites of enhanced organic carbon (OC) burial and may play
an important role in regulating climate change on glacial–interglacial timescales …

Oxygenic photosynthesis fundamentally transformed all major biogeochemical cycles and
increased the size and complexity of Earth's biosphere. However, there is still debate about …
