K-rich mantle metasomatism control of localization and initiation of lithospheric strike-slip faulting
Read more of: K-rich mantle metasomatism control of localization and initiation of lithospheric strike-slip faultingA conceptual model is proposed where bulk transtension, or local transtension during bulk simple shear (resulting from mantle anisotropy- or lithosphere rheology contrasts), of heterogeneously enriched lithospheric mantle, trigger localised […]

Granitoid pluton formation by spreading of continental crust: the Wiley Glacier complex, northwest Palmer Land, Antarctica.
Read more of: Granitoid pluton formation by spreading of continental crust: the Wiley Glacier complex, northwest Palmer Land, Antarctica.The emplacement mechanism, geometry, and isotope geochemistry of plutons of the Wiley Glacier complex suggest that new continental crust grew by multiple injection of tonalitic dykes during dextral transtension in […]

Radiation Belt Environment model: application to space weather nowcasting
Read more of: Radiation Belt Environment model: application to space weather nowcastingA data-driven physical model of the energetic electrons in the Earth’s radiation belts, called the Radiation Belt Environment (RBE) model, has been developed to understand Earth’s radiation belt dynamics and […]

Antarctic marine molluscs do have an HSP70 heat shock response
Read more of: Antarctic marine molluscs do have an HSP70 heat shock responseThe success of any organism depends not only on niche adaptation but also the ability to survive environmental perturbation from homeostasis, a situation generically described as stress. Although species-specific mechanisms […]

Episodicity of Mesozoic terrane accretion along the Pacific margin of Gondwana: implications for superplume–plate interactions.
Read more of: Episodicity of Mesozoic terrane accretion along the Pacific margin of Gondwana: implications for superplume–plate interactions.A review of evidence for deformation and terrane accretion on the Late Triassic–Early Jurassic margins of Pangea and the mid-Cretaceous margins of the palaeo-Pacific ocean shows that deformation was global […]

Potential impact of changes in river nutrient supply on global ocean biogeochemistry.
Read more of: Potential impact of changes in river nutrient supply on global ocean biogeochemistry.The growing world population increases the demand for water, energy, and land. This demand for natural resources impacts the transport of material and the supply of nutrients in the coastal […]

Growth rates of six coccolithophorid strains as a function of temperature.
Read more of: Growth rates of six coccolithophorid strains as a function of temperature.We determined growth rates of six coccolithophorid strains (five species) as a function of temperature. We grew four strains (three species: Emiliania huxleyi, Gephyrocapsa oceanica, and two strains of Calcidiscus […]

Delayed arm regeneration in the Antarctic brittlestar Ophionotus victoriae
Read more of: Delayed arm regeneration in the Antarctic brittlestar Ophionotus victoriaeWe describe the levels of natural arm damage in the Antarctic brittle star Ophionotus victoriae and the rate of arm regeneration over the period of 1 yr, as measured in […]

New Rb-Sr mineral ages temporally link plume events with accretion at the margin of Gondwana.
Read more of: New Rb-Sr mineral ages temporally link plume events with accretion at the margin of Gondwana.Five of six Rb-Sr muscovite mineral isochron ages from the Scotia Metamorphic Complex of the South Orkney Islands, West Antarctica, average 190 ± 4 Ma. The muscovite ages are interpreted […]

Impact of the microstructure of snow on its temperature: A model validation with measurements from Summit, Greenland
Read more of: Impact of the microstructure of snow on its temperature: A model validation with measurements from Summit, GreenlandThe influence of snow microstructure on thermal and radiative transfer in snow has not been thoroughly investigated as the tools necessary to efficiently measure microstructural geometry at millimeter resolution have […]
