    Monitoring (bio)reactive transport in groundwater using geophysics

    Geophysical methods, in particular, spectral induced polarization SIP, capture the changing electrical properties of geologic media as they are modified by biogeochemical reactions. Their unique sensitivity to biogeochemically-induced changes poises non-invasive geophysical approaches at the forefront of novel methodologies that can revolutionize our ability to access the poorly accessible subsurface.

    Methane munchers; A dive into the benthic methane biofilter

    The stability of methane hydrates at continental margins faces a significant threat from rising ocean temperatures. This scenario could potentially trigger the release of substantial (yet unconstrained) amounts of methane into the overlying water column and eventually into the atmosphere. Within marine sediments, the biologically mediated process of anaerobic oxidation of methane (AOM) is critical in mitigating such benthic methane discharge. However, AOM is not always ‘super’-efficient. There are two reasons why.

    Greenhouse gas budgets for two carbon farming options show small or negative climate benefit

    Considerable quantities of soil organic carbon (SOC) can be sequestered in agricultural land by adopting practices broadly known as carbon farming. Two main options for SOC sequestration in arable land are to (1) replace annual crops for perennial crops such as grass or forage legumes, and (2) grow cover crops. Experimental evidence shows that additional perennials and cover crops in temperate agriculture can sequester ca. 300-600 kg C/ha/year.
