  Mapping the evolving strain field during continental breakup from crustal anisotropy in the Afar Depression

  The spatial and temporal scales over which continental breakup occurs by mechanical deformation and magma intrusion remain controversial. Keiret al. quantify anisotropy across the Afar Triple Junction using S-wave splitting from earthquakes to evaluate the strain in a region of continental breakup.

  Prevailing oxic environments in the Pacific Ocean during the mid-Cretaceous Oceanic Anoxic Event 2

  The second oceanic anoxic event occurred 94 million years ago and constituted a very large perturbation of the Earth's carbon cycle. Here, the authors study carbon isotopes and degrees of pyritization and demonstrate that, unlike other oceans, the Pacific remained oxygenated for most of this period.

  Evidence for infragravity wave-tide resonance in deep oceans

  Ocean tides and infragravity waves—the Earths 'hum'—have very different periods and wavelengths. Sugioka and colleagues report resonance between these two phenomena using arrays of broadband ocean-bottom seismometers and show that some tidal energy is transferred to the deep oceans through this coupling.
