The continental margin of SE New Zealand is strongly influenced by the Southland Current and associated water masses. This new seismic stratigraphic study of the margin has revealed a range of depositional mounds and erosional channels that document the close interaction of turbidity and bottom currents in shaping the margin from the Mid‐Eocene onward.

Abstract This study presents a supervised machine learning approach to constructing a 3D geological model for the Lockington area in Victoria, Australia, by integrating borehole observations, geophysical surveys (magnetic, gravity, and radiometric), and elevation data.

Abstract Tectonic subsidence, sea level, and paleoclimate reconstructions using marine records rely on accurate decompaction of the sediment column. Over time, increased overburden pressure from burial decreases sediment porosity with depth. The porosity‐depth relationship is lithology‐dependent and can be represented by an exponential function ...

Nature of the Crust in the Superdeep Bengal Basin Using Teleseismic P Waves
Abstract The Bengal Basin is a sedimentary basin in the northeast region of the Indian subcontinent. It lies between the Indian Shield and the Indo‐Burma Ranges, where the India plate is obliquely subducting under the Burma microplate. Multiple interpretations of the nature of the crust here have been proposed.

Abstract Basin‐filling strata are Mars's historical record of depositional events, including sedimentation by alluvial rivers, and post‐depositional events, including tilting. Measuring stratal tilt on Mars could constrain post‐depositional processes, but is difficult to measure where exposures are 3D and lack clear stratal surfaces, as is often the ...

Rethinking Seawater Mo Isotope Mass‐Balance and the Sedimentary Mo Record
Abstract A lingering misconception is that seawater 98Mo/95Mo ratios should have increased more or less linearly with the oxygenation of Earth's oceans. At the root of this hypothesis is the generalization that oxidizing marine sediments have a stronger affinity for lighter‐mass Mo isotopes than their reducing counterparts.

The making of novel ecosystems: A process‐based framework for measurement, analysis and application
Abstract Ecological novelty is emerging rapidly due to global change drivers such as climate shifts, species introductions, defaunation, and land‐use transformation. These changes challenge how we assess, understand and manage ecosystems in the Anthropocene.
