Phytoplankton remove carbon dioxide from the atmosphere; a new study reveals that marine phytoplankton can also produce greenhouse gases when exposed to ultraviolet radiation.
The Ediacaran features an instable magnetic field complicating paleogeographic reconstructions; a new paleointensity study on late Ediacaran rocks indicates a weak but stable dipolar field.
A simplified representation of polar vortex at monthly scale was revised using a new method, and its daily association with air-sea teleconnections was analyzed to study weather impacts.
A new seismic survey of the Chicxulub impact crater reveals the structure of its peak ring and the sediments that cover it.
A new study accurately captures solar irradiance, which is crucial to understand the energetics and radiation balance of Earth and its influences on the cryosphere, atmosphere, and ocean currents.
A new study pinpoints grain scale dynamics during binary interactions between barchan dunes.
Observations of cross-polar cap neutral winds near 240 km altitude stalling over short distances in the midnight sector near Poker Flat, Alaska, challenge the standard view of high-latitude dynamics.
A combination of waveform tomography and hydrothermal modelling allows characterizing the mechanisms and reach of fluid flux and ocean plate cooling near mid-ocean ridges with unprecedented detail.
Using cutting-edge observations, reanalyses, and climate models, a new study projects the outbreak of temperature extremes over new global areas by 2100.
A new analytical model describes how the amount and grain size of sediment transported by rivers influences bedrock channel width, which can be used to predict where rivers will widen or narrow.
