Zones coastal

The magnitude and fate of coastal-zone biological production is a major unknown in the global carbon cycle. Since river nutrient flux into these regions may be altered with C02-induced climate change, it is important that generation and fate of coastal-zone production be better understood.

Table 8.2 shows a moderate reduction in the total COD concentration under transport of the wastewater in the sewer. Also important is an increase in the slowly biodegradable or nonbiodegradable COD fractions — primarily corresponding to production of particulate organic matter (heterotrophic biomass). This COD fraction can undergo removal by the physicochemical treatment process. However, the most important result of the aerobic biotransformations in the sewer is the considerable reduction in the easily biodegradable, i.e., soluble and colloidal, COD fractions that otherwise would be discharged into the coastal zone.

In addition to the man-made environmental problems that have affected the Caspian adversely, the sea has exhibited a curious natural variation in its water level that has created additional problems and has wrought havoc on coastal infrastmcture. Since 1978, the sea level has risen almost 7.5 feet. Flooding in coastal zones has inundated residential areas, transport, telecommunications and energy infrastructure, chemical and petrochemical industries, croplands and hatcheries, forcing thousands of residents to be evacuated from flooded homes. In Turkmenistan, the town of Dervish, which is detached from the western part of the mainland, is turning into an island due to the rise in sea level, and Cheleken and Karakul are sinking into the water as well. 

In another study, samples from the Dutch coastal zone of the North Sea were collected in 1999 and 2000 and analysed by LC-ESI-MS [31]. At locations corresponding to those of the 1995/1999 studies, levels (10-30ngNPEOg 1) were observed in close agreement with the ones reported earlier. It can be concluded that, provided careful evaluation of which commercial mixture will be used as a calibrant in LC-FL, the result thus calculated can be similar to those obtained by LC-MS.

An increase has also been observed in the LAS concentration in the aqueous phase during the cold season, due to reduced microbial activity [3,18,23]. Therefore the flow of LAS towards the coastal zone will be strongly influenced by the seasonal variable as confirmed by the values obtained by Takada et al. [3], who found that for the Tamagawa estuary the flow of LAS was five times higher in winter than in summer. However, in long-term monitoring [6,31,32], the variations detected are principally a function of tidal influence and of the time of day, or the day of the week, when the LAS is introduced into the system [6,33],... 

The relatively high heat capacity of water has important consequences for climate and life on Earth. For example, seasonal changes in atmospheric temperatures are moderated at mid-latitudes via adsorption of heat by the ocean s surfece waters during the summer and release of this heat diudng the winter. Thus, mid-latitude coastal zones experience much smaller seasonal atmospheric temperature fluctuations than occur inland.
