measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of caspian sea penetration into anzali wetland was determined. the results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. a pattern of saltwater and freshwater interface is presen...

The interface layer between ocean and atmosphere is only a couple of micrometers thick but plays a critical role in climate relevant processes, including the air-sea exchange of gas and heat and the emission of primary organic aerosols (POA). Recent findings suggest that low-level cloud formation above the Arctic Ocean may be linked to organic polymers produced by marine microorganisms. Sea ice...

This paper reports on the development of an acoustic sea ice thickness measurement sensor. The development is applying acoustic NonDestructive-Testing (NDT) techniques to test first year sea ice including significant amounts of enclosed air bubbles. Two single piezoelectric transducers are tightly placed on smoothed sea ice surface to emit and receive acoustic signals. Besides seeing a detectab...

(1) Analyze and model sea surface scattering measurements, and sea surface environmental measurements, made during the Asian Seas International Acoustics Experiment (ASIAEX) conducted in the East China Sea (May-June 2001). The acoustic data consist of measurements of vertical coherence for single and multiple-interaction forward scattering from the sea surface, made simultaneous with measuremen...

[1] The heat and mass balance of the Arctic Ocean is very sensitive to the growth and decay of sea ice and the interaction between the heat and salt fields in the oceanic boundary layer. The hydraulic roughne ss of sea ice controls the detailed natur e of turbulent fluxe s in the boundar y layer and hence is an important ingredient in model parameterizations. We describe a novel mechanism for t...

The coastal area is a multi-issue area and its observation provides heterogeneous geographical database. Challenges are located on the integration and the rendering of these data: (1) geographic data used to characterize the sea must be combined to obtain water depth and sea/land interface (data heterogeneity problem) and (2) current visualization systems do not provide continuous rendering on ...
