One of the most intriguing attributes of Earth's magnetic field is that it reverses polarity. Previous palaeomagnetic records mainly from the last ~17 million years indicate that the reversal process typically occurs over ten thousand or fe...

Archean ocean marine primary productivity may have been limited by biologically available nitrogen. Due to low molybdenum abundances, early biological nitrogen fixation is thought to have relied on alternative nitrogenases that incorporate ...
Oxidative uptake of Ce by oceanic ferromanganese crusts and implications for paleoredox estimates using Ce isotopes [0.03%]

The oxidative enrichment and isotopic fractionation of cerium (Ce) in contact with vernadite (δ-MnO2) serve as a proxy for past redox conditions in both terrestrial and marine environments. However, the molecular processes that govern the ...

The Gulf Stream is important for the climate system through its transport and air-sea exchange of heat. What is less well accepted is the role of the Gulf Stream in the carbon cycle. Here we examine how the Gulf Stream provides a "biogeoche...

Sea surface temperature is a key indicator of climate change on Earth and is central to all related modelling endeavours. However, sea surface temperature is notoriously difficult to reconstruct accurately in the geological record, especial...

Snow water is key to water supply in cold regions and beyond. Here we introduce Snow Water Availability that quantifies water stored in the snow-covered portion of an area. By integrating a plausible set of available gridded datasets for sn...

The surface and interior ocean are connected through physical processes that act in three dimensions and on subseasonal timescales. Numerical models and observations both highlight the importance of these eddying dynamics on shaping the bio...
Coral tissue depth reconstructed using skeletal microstructural offsets is driven by environmental stress [0.03%]

Coral tissue depth reflects organismal health and is influenced by environmental stressors. Reconstructing its past variability on inter- and intra-annual timescales, however, is not yet possible. Here we reconstructed seasonal tissue depth...
