It has been suggested that increasing terrestrial water discharge to the Arctic Ocean may partly occur as submarine groundwater discharge (SGD), yet there are no direct observations of this phenomenon in the Arctic shelf seas. This study tests the hypothesis that SGD does exist in the Siberian Arctic Shelf seas, but its dynamics may be largely controlled by complicated geocryological conditions such as permafrost. The field-observational approach in the southeastern Laptev Sea used a comb...

The extreme mobility of submerged sand bars at the mouth of the Cananeia outlet has made safe access difficult to the lagoonal region of Cananeia, on the southern coast of the State of São Paulo. This problem is serious enough to have been treated by various authors over the past thirty years. Erosional and depositional processes in the area are the result of the combined very often conflicting action of tidal currents, waves, and longshore currents that are active in the dispersal of the sand s...

Ambient aerosols play an important role in atmospheric processes affecting the human and natural environments. They affect air quality, reduce visibility, and induce climate change by directly scattering and/or absorbing the incoming solar radiation (Charlson et al., 1992; Kim et al., 2006), or indirectly by acting as cloud condensation nuclei (Hobbs, 1993). Aerosol particles are emitted from a variety of anthropogenic and natural sources either directly into the atmosphere or as secondary parti...
