TL;DR: In this paper, the authors show that the surface enrichment is the result of a minor amount of transport and deposition by aqueous processes on the surface of olivine-bearing basalts.

TL;DR: The Mars Exploration Rover Opportunity has investigated the landing site in Eagle crater and the nearby plains within Meridiani Planum, and the rocks are interpreted to be a mixture of chemical and siliciclastic sediments formed by episodic inundation by shallow surface water, followed by evaporation, exposure, and desiccation.
Journal ArticleDOI
Dust and Biological Aerosols from the Sahara and Asia Influence Precipitation in the Western U.S.
Jessie M. Creamean,Kaitlyn J. Suski,Daniel Rosenfeld,Alberto Cazorla,Paul J. DeMott,Ryan C. Sullivan,Allen B. White,F. Martin Ralph,F. Martin Ralph,Patrick Minnis,Jennifer M. Comstock,Jason Tomlinson,Kimberly A. Prather +12 more
TL;DR: This study presents the first direct cloud and precipitation measurements showing that Saharan and Asian dust and biological aerosols probably serve as IN and play an important role in orographic precipitation processes over the western United States.
Journal ArticleDOI

TL;DR: This work describes a newly developed approach for reproducing the chemical complexity of SSA in a laboratory setting, comprising a unique ocean-atmosphere facility equipped with actual breaking waves and shows SSA size and chemical mixing state are acutely sensitive to the aerosol production mechanism, as well as to the type of biological species present.
Journal ArticleDOI
Direct observations of the atmospheric processing of Asian mineral dust
TL;DR: In this article, the accumulation of secondary acids and am- monium on individual mineral dust particles during ACE-Asia has been measured with an online single-particle mass spectrometer, the ATOFMS.
