Modeling pN2 through Geological Time: Implications for Planetary Climates and Atmospheric Biosignatures [PDF]
, 2016 Nitrogen is a major nutrient for all life on Earth and could plausibly play a similar role in extraterrestrial biospheres. The major reservoir of nitrogen at Earth's surface is atmospheric N2, but recent studies have proposed that the size of this ...

Geophysical Research Letters, Volume 50, Issue 20, 28 October 2023., 2023 Abstract Surface deformation plays a key role in illuminating magma transport at active volcanoes, however, unambiguous separation of deep and shallow transport remains elusive. The Socorro Magma Body (SMB) lacks an upper crustal magma transport system, allowing us to link geodetic measurements with predictions of numerical models investigating ...

Geophysical Research Letters, Volume 50, Issue 17, 16 September 2023., 2023 Abstract We obtain new images of the 3D resistivity structure of the Wudalianchi volcanic field (WVF). No low‐resistivity structure is found beneath Laoheishan and Huoshaoshan volcanoes in the WVF, which challenges the hypothesis of one or more magma reservoirs in the upper crust of this region. We observe a low‐resistivity body beneath Weishan volcano;

Case Studies in Construction Materials, 2023 One of the most important parameters when it comes to heat losses in buildings is the thermal transmittance or U-value. Therefore, great importance should be given to the determination of U-values, especially for elements where there is a high thermal ...

Heat-flow value of Late Mesozoic to Cenozoic in Putumayo Sub-Basin, Republic of Colombia
Shiyou shiyan dizhi, 2020 The heat-flow history of the Putumayo Sub-Basin has undergone a long-term and complex evolutionary process from the Late Mesozoic to the Cenozoic due to multiphases of tectonic evolution. The regional geologic background and the forward modeling of paleo-

Geothermal heating, diapycnal mixing and the abyssal circulation [PDF]
Ocean Science, 2009 The dynamical role of geothermal heating in abyssal circulation is reconsidered using three independent arguments. First, we show that a uniform geothermal heat flux close to the observed average (86.4 mW m<sup>−2</sup>) supplies as
