The paper considers laboratory results of the composition, structure and properties for frozen and thawed soils at west coast of Baydara Bay. Experimental data of unfrozen water content and thermal properties are discussed and summarized for different soils. The roles of soil salinity and organic matter content on these data were estimated for frozen and thawed soils.

Salt spray is an important abiotic stress that affects plant and other biotic communities in the vicinity of sea coasts. Salt stress refers only to excess of ions in the environment, but along sea coasts it specifically involves increased amounts of Na+ and Cl− ions. Anyone who has visited a sea coast on windy days has experienced the landward movement of salt in the form of salt spray. Salisbury (1805) reported details of a marine storm in England following gale force winds from the east for one week. He writes: ‘On the 14th of January 1803, I observed an east window of my house, which had been cleaned a few days before, covered on the outside with an apparent hoar frost.’ Chemical analysis showed that it was salt from salt spray that had been deposited on plants, buildings and other objects. In spring of that year he made two observations: (i) plant taxa showed differential tolerance to salt spray and (ii) injury was more pronounced on the windward than the leeward sides of plants. Salt spray acts as a strong environmental stress and populations of biotic organisms have evolved traits that allow them to tolerate the effects of salt. The salt crystals also act as condensation nuclei in the air and damage plants by abrasion during wind storms. However, salt spray may also be beneficial because it improves plant growth by providing some essential nutrients. Many researchers have examined the role of salt spray on survival, distribution and growth form of plant species. In this chapter the effects of salt spray and soil salinity on seed germination, seedling survival and plant growth will be examined. Symptoms of injury to plants, mechanisms of salt tolerance and comparisons between plant species native to the coastal dunes will also be discussed. Three factors—wind speed, wave amplitude and wind direction—influence the formation of salt spray. Waves of high amplitude produce four basic types of breakers: surging, collapsing, plunging and spilling. The steepest waves with high turbulence create spilling breakers with a bore accompanied by large quantities of small foam bubbles.

Adhesive Bonded Joints

Durability of adhesive bonded joints in moisture and salt spray environments is essential to USAF aircraft. Structural bonding technology for aerospace applications has depended for many years on the preparation of aluminum surfaces by a sulfuric acid/sodium dichromate (FPL etch) treatment. Recently, specific thin film anodizing techniques, phosphoric acid, and chromic acid anodizing have been developed which not only provide good initial bond strengths but vastly improved environmental durability. These thin anodic films are in contrast to the commonly used thick anodic films such as the sulfuric acid or "hard" sulfuric acid anodic films which are highly corrosion resistant in themselves, but which do not provide good initial bond strengths, particularly in low temperature peel.The objective of this study was to determine the characteristics of anodic films on aluminum alloys that make them corrosion resistant. The chemical composition, physical morphology and structure, and mechanical properties of the thin oxide films were to be defined and correlated with the environmental stability of these surfaces in humidity and salt spray. It is anticipated that anodic film characteristics and corrosion resistance will vary with the anodizing processing conditions.
