Changing atmospheric acidity as a modulator of nutrient deposition and ocean biogeochemistry

Science Advances, 2020
Changing atmospheric acidity alters the delivery of nutrients to the ocean and affects marine productivity and ecology. Anthropogenic emissions to the atmosphere have increased the flux of nutrients, especially nitrogen, to the ocean, but they have also ...

Deposition of Aerosols onto Upper Ocean and Their Impacts on Marine Biota

Atmosphere, 2021
Atmospheric aerosol deposition (wet and dry) is an important source of macro and micronutrients (N, P, C, Si, and Fe) to the oceans. Most of the mass flux of air particles is made of fine mineral particles emitted from arid or semi-arid areas (e.g ...

Laboratory experiments and models of diffusive emplacement of ground ice on Mars [PDF]

, 2009
Experiments demonstrate for the first time the deposition of subsurface ice directly from atmospheric water vapor under Mars surface conditions. Deposition occurs at pressures below the triple point of water and therefore in the absence of a bulk liquid ...

Widespread impacts to precipitation of the East Palestine Ohio train accident

Environmental Research Letters
On 3 February 2023, a Norfolk Southern train derailment occurred in East Palestine, Ohio. The accident and subsequent fire resulted in the emissions of large amounts of hazardous compounds to the ambient atmosphere over many days.

Atmospheric Hg(0) dry deposition over environmental surfaces: Insights from mercury isotope fractionation

Eco-Environment & Health
Atmospheric Hg(0) dry deposition is a vital process that significantly affects the global distribution and cycling of Hg. However, significant knowledge gaps and challenges remain in understanding atmospheric Hg(0) deposition and its subsequent post ...

Response patterns of moss to atmospheric nitrogen deposition and nitrogen saturation in an urban–agro–forest transition [PDF]

Atmospheric Chemistry and Physics
Increasing trends of atmospheric nitrogen (N) deposition resulting from a large number of anthropogenic emissions of reactive N are dramatically altering the global biogeochemical cycle of N.

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

Molecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

Western Pacific atmospheric nutrient deposition fluxes, their impact on surface ocean productivity [PDF]

, 2014
The atmospheric deposition of both macronutrients and micronutrients plays an important role in driving primary productivity, particularly in the low-latitude ocean.
