    The authors use seismic and sedimentology data to estimate the volume of the Minoan eruption. The results show that the Plinian phase contributed most to the distal tephra fall, and that the pyroclastic flow volume is significantly smaller than previously assumed.

    The archetypal supergreenhouse Cretaceous Earth had an active cryosphere with permafrost in plateau deserts. A modern analogue is the aeolian–permafrost system from the Qiongkuai Lebashi Lake area, Xinjiang Uygur Autonomous Region, China.

    Submarine fans play an important role in routing sediment in continental and deep water settings. Here the authors develop a framework is to explain the shape of submarine fans using a numerical model framework which can either predict seafloor topography from turbidity current flow properties or infer these flow properties from seafloor topography.

    South American cordilleran orogenic systems have repeated complex magmatic and deformation histories. Here the authors analyze detrital zircons found in the Amazon deep-sea fan that record mountain-building events and reveal cycles of orogenesis with periods of ~60–90 Myr since the Phanerozoic.

    A climate sensitive permafrost region (Yedoma domain) was found to contain globally relevant N stock of >40 Gt nitrogen, of which 4 to 16 Gt of the N could become available by thaw until 2100. This study increases the current estimates by nearly 50%.

    Astrochronology of a core in Maryland suggests that the onset of the Paleocene-Eocene Thermal Maximum (PETM) warming lasted about 6 thousand years. These data are more consistent with astronomical forcing than an extraterrestial trigger for the PETM.

    This study found that millennial periods of higher rainfall combined with rising sea level enhanced sediment accumulation in Amazonian rivers valleys. This fuelled synchronous expansion of vegetation adapted to seasonally flooded substrates and its specialized bird populations, showing how global climate changes can affect specific Amazonian species.

    The Chengjiang Biota is the earliest most diverse animal community from the Cambrian Explosion (~518 million years ago). This biota is shown to have colonized a delta, highlighting the importance of this shallow environment in recording early snapshots of life on Earth.

    Sand spikes, sandstone bodies that have been enigmatic for nearly two centuries, represent a new type of seismite and a promising tool to identify strong impact-induced or tectonic paleo-earthquakes and their source regions in the geologic record.

    The role of Southern Ocean gateways contributing to the Eocene-Oligocene climate transition is still debated. Here, the authors present high-resolution ocean simulations to show that gateways opening led to a reorganization of ocean circulation, heat transport and Antarctic surface water cooling.

    Harmful algal and bacterial blooms are increasingly frequent in lakes and rivers. From the Sydney Basin, Australia, this study uses fossil, sedimentary and geochemical data to reveal bloom events following forest ecosystem collapse during the end-Permian event and that blooms have consistently followed warming-related extinction events, inhibiting the recovery of freshwater ecosystems for millennia.

    Reconciling the Snowball Earth hypothesis with sedimentological cyclicity has been a persistent challenge. A new cyclostratigraphic climate record for a Cryogenian banded iron formation in Australia provides evidence for orbital forcing of ice sheet advance and retreat cycles during Snowball Earth.

    There is a lot of uncertainty about what Earth’s climate and geography were like in the early Cambrian, when animal life diversified throughout the oceans. Here we show that numeric comparisons of model simulations and climatically influenced rocks can help constrain geography and climate during this time.

    Present et al. examine the processes controlling lithification of microbial mats in a Caribbean peritidal carbonate environment. The authors present sedimentological and geochemical evidence of a surprising bias against preserving the most robust, widespread microbial ecosystems in the sedimentary record.

    This study investigates the underlying physical mechanisms of turbidity currents travelling thousands of miles in confined submarine settings, rather than diffusing after short distance. Using high resolution simulations with up to a billion grid points helps to understand the evolving layered structure of a current.

    The authors here present a multi-lake paleoseismological approach to evaluate the role of earthquakes in causing a spatio-temporal cluster of large, prehistoric rockslides between 3000 and 4200 years ago in the Eastern European Alps and for which the triggering mechanisms are still debated.

    Human activities have accelerated soil erosion and landscape change in many areas. Here the authors show how rates of erosion, sediment transfer and alluvial sedimentation have increased by an order of magnitude across North America since European colonization, far exceeding the rates expected of natural processes.

    Phosphorus is an essential nutrient critical for agriculture, but because it is non-renewable its future availability is threatened. Here the authors show that across the globe most nations have net losses of phosphorus, with soil erosion as the major route of loss in Europe, Africa and South America.

    The proliferation of dams since 1950 has promoted sediment deposition in reservoirs, which is thought to be starving the coast of sediment and decreasing resistance to storms and sea-level rise. Here, the authors show that century-long records of sediment mass accumulation rates and sediment accumulation rates more than doubled after 1950 in coastal depocenters around North America.

    Identification of stratospheric volcanic eruptions in the geological record and their link to mass extinction events during the past 540 million years remains challenging. Here, the authors report unexpected, large mass-independent sulphur isotopic compositions of pyrite in Late Ordovician sedimentary rocks, which they suggest originates from stratospheric volcanism linked to the first pulse of the Late Ordovician mass extinction.

    Tidewater glaciers in fjords can advance/retreat independent of climate due to stabilization by sediments at their termini. We show that an Alaskan paleo-ice stream behaved similarly on an open shelf, suggesting that increased sediment flux may delay catastrophic retreat of outlet glaciers in a warming world.

    A reference function for describing the orientation of clay platelets in clay-rich materials is still lacking, but is necessary for applications such as prediction of water and solute transfer and designs of innovative materials. Here, the authors determine a reference orientation function of clay platelets, and validate their function for both engineered and natural clay-rich media.

    Marine chemistry during the Early Earth (over 2.7 billion years ago) is commonly inferred to have been inorganically sulfate-reducing. Here, the authors argue that organic sulfur cycling may have played a previously unrecognized, yet important, role in the formation of ancient Archean marine sulfides.

    The transition from smectite to illite requires potassium incorporation, yet the role of microbes in facilitating K+ uptake remains debated, especially during the early Earth. Here, the authors suggest that the Paleoproterozoic microbial mats extracted potassium from sea water and induced localized illitization during early low-temperature diagenesis.
