Top‐Down Versus Bottom‐Up Atmospheric Emission Estimates From Oil and Natural Gas Operations
Earth's Future, Volume 13, Issue 11, November 2025.Abstract This study reviews results from literature to investigate top‐down versus bottom‐up emission estimates from oil and natural gas (O&NG) operations. Ten years ago, a landmark study by Brandt et al. (2014, https://doi.org/10.1126/science.1247045) found generally higher top‐down emissions determinations than industry estimates.

AGU Advances, Volume 6, Issue 5, October 2025.Abstract Coccolithophores are a group of marine phytoplankton precipitating about 50% of total calcite carbonate in the surface ocean. During the Pleistocene, coccolithophores experienced several periodic high‐abundance and dominance intervals (acmes) that significantly altered the ocean carbon cycle by increasing the production of carbonate in the ...

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.Abstract The nature and cause(s) of the Mid‐Pleistocene Transition (MPT) remain enigmatic. Notably, the role of tropical Pacific oceanographic changes during the late MPT (∼0.9–0.6 Ma) remains understudied. Here, we generated ∼1.4‐Myr‐long Mg/Ca and δ18O records for the planktonic foraminifer Trilobatus sacculifer from IODP Site U1490 to reconstruct ...

Radon-thoron measurements in air and soil from some districts of northern part of India [PDF]
Nuclear Technology and Radiation Protection, 2015 Radon, thoron and their progenies in the indoor environment are considered as one of the health hazards. The alpha emitting nature of these gases made it possible to detect in indoor environment with the help of nuclear track detector techniques.

Determination of thoron equilibrium factor from simultaneous long-term thoron and its progeny measurements [PDF]
Radiation Protection Dosimetry, 2011 With 3-month simultaneous measurements of thoron and its progeny concentrations in the lowest floors of 109 homes, the geometric mean (GM) of thoron equilibrium factor was determined to be 0.019 with a geometric standard deviation (GSD) of 3.63. Combined with the analysis from results obtained from a previous study in 138 homes, the GM of thoron ...

Journal of Geophysical Research: Oceans, Volume 130, Issue 8, August 2025.Abstract Shifts in the phytoplankton assemblage induced by environmental changes have significant implications for carbon cycling and marine food webs, but remain poorly constrained across spatiotemporal scales. Here, we investigate the effects of rising sea surface temperatures and increased stratification on the phytoplankton composition and size in ...
