    "Joe Balkoski has just written the finest book about Utah Beach." (Bill Stone Stone & Stone Second World War Books ) "[Balkoski] provides a convincing, thoughtfully crafted narrative buttressed by facts and statistics that unequivocally recasts how one views both Utah Beach and the associated airborne operations."/5(88).   This study reports on ambient measurements of organosulfur (OS) and methanesulfonate (MSA) over the western United States and coastal areas. Particulate OS levels are highest in summertime, and generally increase as a function of sulfate (a precursor) and sodium (a marine tracer) with peak levels at coastal by:

INTRODUCTION This study is concerned with the inland penetration of airborne sea-salt particles. Sea-salt particles originate as tiny droplets of sea water that are injected into the air when tiny bubbles rise to the sea surface and burst.

These bubbles result mainly from breaking waves. Download PDF: Sorry, we are unable to provide the full text but you may find it at the following location(s): (external link). Airborne data revealed greater evidence of sea salt in clouds on clearing days, pointing to a possible role for, or simply the presence of, this aerosol type in clearing areas coincident with.

In a TEM study of North Atlantic aerosol particles (Pósfai et al., ), many of such cloud-processed, internally mixed sea-salt/mineral particles contained anhydrite, but none of them contained calcite; during the transport over the ocean, calcite reacted with SO 2 or sulfate and formed anhydrite.

The Mediterranean Sea (MS) is an ideal marine environment to study airborne microbes. The MS is a low-nutrient low-chlorophyll (LNLC) ecosystem [ 21, 22 ], and the surrounding landmasses provide ample aerosols: The densely populated land to the north is a source of anthropogenic aerosols, and the arid land to the south is a source of mineral dust [ 20 ].Cited by: 1.

In addition, concrete structures are greatly affected by salt attack primarily due to airborne sea salt like it can be seen through the corrosion of study intends to investigate salt.

Rossknecht et al. () found similar patterns of airborne sea salt particle concentration for measurements made from the Oregon (USA) coast and inland. A rapid decrease in the first 2–5 km and then a slower decreasing rate further inland was by: the same period the Department used samples in a paleontological study of northwestern Oregon.

It should be noted that most of the previous observations and estimates mentioned above were not conducted in open ocean areas. The range of the concentrations of total airborne bacteria over the Kuroshio Extension region was from × 10 4 to × 10 5 cells m −3, and the mean was × 10 4 cells m − by: 8.

The individual aerosol particles may be solid, liquid, or of a mixed variety, and all types are found in the earth's atmosphere. The size classification of aerosol particles is greatly facilitated if the particles are assumed to have a spherical shape. The size.

Wind-blown mineral dust tends to be made of mineral oxides and other material blown from the Earth's crust; this particulate is light-absorbing. Sea salt is considered the second-largest contributor in the global aerosol budget, and consists mainly of sodium chloride originated from sea spray; other.

Also notable during the summertime in the region is efficient aqueous chemistry to produce SOA, especially organic acids, and secondary sulfate (Sorooshian et al., ) that can subsequently interact with sea salt particles.

Similar to fresh sea salt, the CWT map for aged sea salt shows that the major sources reside over the Pacific Ocean Cited by: These dust particles may interact with gaseous pollutants such as SO 2 or other aerosols during their transit, for example by collecting soot or sea salt or by gas to particle conversion.

Introduction [2] Estimates of the global mean direct radiative forcing by mineral dust vary in the range + to − W m −2 [Haywood and Boucher, ], owing to uncertainties in the chemical composition, size distribution, and source strength of dust particles [Sokolik et al., ].Dust particles have diameters up to several microns and a nonzero imaginary part of Cited by:.

The total deposition of sea salt was calculated to be × 10 12 g/yr in the whole of Japan (area × 10 5 km 2) and the mean concentration of chloride in rain to be ppm over Japan as a whole, but the concentration is about 3 times larger over the Japan Sea coastal region than over the Pacific coast region, owing to the violent north Cited by:   Dominant biological component of airborne coarse particles are fungal spores.
