In coastal areas groundwater quality may be degraded by intrusion of salt sea water into freshwater aquifers. The salinity of the groundwater changes its physical properties: an increase in salinity increases both the density and viscosity of the groundwater. These density differences are the primary driving force that allows salt water to move into the coastal aquifer, forming a salt water “we...

Bile salt synthesis is a specialized liver function in vertebrates. Bile salts play diverse roles in digestion and signaling, and their homeostasis is maintained by controlling input (biosynthesis) and intestinal conservation. Patients with biliary atresia (i.e., obliteration of the biliary tree) suffer liver fibrosis and cirrhosis. In contrast, sea lamprey thrives despite developmental biliary...

The ozonolysis of 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) adsorbed on salt mixtures as models for sea-salt particles was studied in real time using diffuse reflection infrared Fourier transform spectrometry (DRIFTS) at room temperature with and without added water vapor. The salt substrates were a mixture of MgCl(2)·6H(2)O with NaCl or a commercially available synthetic sea salt...

The first report, to our knowledge, on the occurrence of filamentous fungi in the hypersaline (340 g salt l-1) Dead Sea is presented. Three species of filamentous fungi from surface water samples of the Dead Sea were isolated: Gymnascella marismortui (Ascomycota), which is described as a new species, Ulocladium chlamydosporum and Penicillium westlingii (Deuteromycota). G. marismortui and U. chl...

The basic premise behind the retrieval is to iterate the mixing ratios of two aerosol models for each size mode. (Weakly and a strongly absorbing aerosol models are used for the fine mode, sea salt and dust models are used for the coarse mode.) Ideally, the retrieval will produce the mixing ratios that best describe the measured radiances at 3-4 wavelengths. (The mixing ratio of dust and sea sa...

We present a fixed-lag ensemble Kalman smoother for estimating emissions for a global aerosol transport model from remote sensing observations. We assimilate AERONET AOT and AE as well as MODIS Terra AOT over ocean to estimate the emissions for dust, sea salt and carbon aerosol and the precursor gas SO2. For January 2009, globally dust emission decreases by 26% (to 3,244 Tg/yr), sea salt emissi...

A survey of atmospheric aerosols in a suburban area near Tokyo, Japan was conducted using an Andersen sampler. Significant amounts of Na and Cl collected were considered to be derived from sea salt. The difference between the Na/Clratio in the area and that in sea salt indicated a considerable loss of Cl. This is assumed to be caused by the formation of NaNO3, which is one of the main nitrate s...
