Influence of human pressures on large river structure and function [PDF]
, 2009 A large river study was conducted as part of the Cross Departmental Research Pool (CDRP) ecological integrity project to (i) provide an overview of the macroinvertebrate faunas of large rivers, including those in deep-water habitats, and (ii) to ...

Extended Kelvin–Voigt Model for Simulating Thermally Accelerated Creep in Fine‐Grained Soils
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The subsurface undergoes temperature variations in many situations due to anthropogenic and natural causes, which strongly influence the long‐term behavior of soils. These phenomena can involve temperature anomalies in the ground across distances of a few meters, as in the case of nuclear waste repositories, to distances encompassing entire ...

Microbial Nitrogen Cycling Becomes Conservative and Resilient to Long-Term Warming in High-Latitude Carbon-Limited Soils. [PDF]
Glob Chang BiolWe investigated how long‐term soil warming affects microbial nitrogen use in subarctic ecosystems. After about five years, warming led microbes to shift toward greater reliance on organic nitrogen and tighter conservation of mineral nitrogen, reducing potential nutrient losses.

Geothermal Gradient Measurement using a Deep Sea Corer [PDF]
Geophysical Journal International, 1963 Summary An apparatus to measure heat flow through the ocean floor in conjunction with standard coring techniques has been independently developed at Cambridge. Experimental and theoretical work have shown that the probe configuration used is free from systematic error in the temperature measurement due to heat generated by friction when the device ...

Reservoirs and radiocarbon: 14C dating problems in Myvatnssveit, Northern Iceland [PDF]
, 2007 This paper examines 2 potential sources of the radiocarbon offset between human and terrestrial mammal (horse) bones recovered from Norse (~AD 870–1000) pagan graves in Mývatnssveit, north Iceland.

A Parallelized 3D Geomechanical Solver for Fluid‐Induced Fault Slip in Poroelastic Media
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT We present a fully implicit formulation of coupled fluid flow and geomechanics for fluid injection/withdrawal in fractured reservoirs in the context of CO2$\textrm {CO}_2$ storage. Utilizing a Galerkin finite‐element approach, both flow and poroelasticity equations are discretized on a shared three‐dimensional mesh.
