Origin of Life Molecules in the Atmosphere After Big Impacts on the Early Earth [PDF]

open access: yesarXiv, 2023
The origin of life on Earth would benefit from a prebiotic atmosphere that produced nitriles, like HCN, which enable ribonucleotide synthesis. However, geochemical evidence suggests that Hadean air was relatively oxidizing with negligible photochemical production of prebiotic molecules.

Estimating Denitrification Rates in the East/Japan Sea Using Extended Optimum Multi-Parameter Analysis

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2015
Denitrification rates in the East/Japan Sea (EJS) were examined with extended Optimum Multi-Parameter (eOMP) analysis. The potential denitrification locations expected from the eOMP analysis occurred only in the Ulleung Basin (UB) and near the Tatar ...

Atmospheres of science: Experiencing scientific mobility [PDF]

open access: yesSocial Studies of Science, 2020
This article uses notions of the atmospheric to engage with empirical material concerned with international mobility in science. It draws on recent conceptual work on atmospheres that frames them as allowing access to the affective qualities of everyday life and as ‘productively nebulous’: atmospheres exist between the local and the globally diffuse ...

Measurements and Mesoscale Modeling of Autumnal Vertical Ozone Profiles in Southern Taiwan

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2008
Vertical measurements of ozone were made using a tethered balloon at the Linyuan site in Kaohsiung County, southern Taiwan. Ozone was monitored at altitudes of 0, 100, 300, 500, and 1000 m from November 23 to 25 in 2005.
