Salinity representations

Fig. 4. Schematic representation of surface currents in the north Atlantic Ocean and stations where surface waters were collected. Areas I to V indicate regions with common temperature, salinity and nutrient characteristics.

There should be good representation of local recent groundwaters, for example, the full spectrum of salinity, chemical composition groups, and temperatures.

Figure 9.32 is a diagrammatic representation of those parts of the eye involved in dmg absorption. The cornea and the conjuctiva are covered with a thin fluid film, the tear film, which protects the cornea from dehydration and infection. Cleansed comeal epithelium is hydrophobic, physiological saline forming a contact angle of about 50° with it, and it has, in this clean condition, a critical surface tension of 28 mN m b The aqueous phase of tear fluid is spread by blinking. 

Theoretical diffusion path studies were made with a model system for comparison to the experimentally observed phenomena. A pseudoternary representation was chosen for modeling the phase behavior, and brine and oil were chosen as the independent diffusing species. For simplicity and because their exact positions and shapes were not known, phase boundaries in the liquid crystal region were represented as straight lines. Actually, studies indicate a rather complex transition from liquid crystal to microemulsions as system oil content is increased, especially near optimum salinity (15-16). A modified Hand scheme was used to model the equilibria of binodal lobes (14,17). Other assumptions are described in detail elsewhere (13). 

The fast changes in the transition area are illustrated in Fig. 19.5, which shows model snapshots of current patterns and of salinity distribution at intervals of 14-28 h. The simulations are carried out with a horizontal grid resolution of 1 nautical mile and reproduce the observations of a ship campaign very well (see Schmidt et al., 1998). This combined approach of field measurements and modeling revealed that the typical processes in the Belt Sea are too fast for a synoptic representation of data measured by ships. During a ship survey of two to three days, currents may change direction several times and a combination of the data into a quasi-synoptic picture may suggest spurious spatial correlations. 

The variation of the phase behaviour as a function of the salinity is shown in Fig. 1.10(b) in the form of an (y)-section through the phase tetrahedron of the quaternary H20/NaCl-n-decane-A0T system at a = 0.50 and a constant temperature of T = 40° C. In order to compare the variation of the phase behaviour with temperature and salinity a rectangular representation is used also for the (y)-section through the phase tetrahedron. As can be seen, the phase boundaries also resemble the shape of a fish in this isothermal (y)-section. However, with increasing mass fraction of salt the phase sequence 2, 3, 2 is found which is inverse to the 2, 3, 2 sequence observed with increasing temperature. 

The first representation is to select one formulation variable to be scanned (at all others constant) and to plot the variations of a property or of the phase behaviour versus this formulation variable. Figure 3.1(a) shows such a plot of interfacial tension (y) versus the salinity (S) of the aqueous phase together with the ranges in which different phases are formed for a system containing n-hexane as oil, an alkylbenzene sulphonate surfactant and sec-butanol as co-surfactant. The phase behaviour is indicated as 2 or 2 for two-phase systems in which the surfactant-rich phase is the lower water or the upper oil phase, corresponding to Winsor type I and II diagrams. Symbol 3 indicates the range of formulation for which a three-phase behaviour is attained. 

For a given M, the difference between the lattice energies of MX and MX 2 is greatest for X = F, so if any saline halide MX +2 is formed, it will be the fluoride. This treatment is probably a good representation of the conversion of TIF into TlFj, and PbF2 into PbF4. 

N 47°W, with strontium/chlorinity contours indicated, although because of the limited amount of data no detailed diagram results, there is a correlation with a similar representation using the more numerous salinity data. This indicates certain water masses may be identified and their origins estimated to some degree by their strontium/chlorinity ratio. 

The statistical collection and representation of the weather conditions for a specified area during a specified time interval, usually decades, together with a description of the state of the external system or boundary conditions. The properties that characterize the climate are thermal (temperatures of the surface air, water, land, and ice), kinetic (wind and ocean currents, together with associated vertical motions and the motions of air masses, aqueous humidity, cloudiness and cloud water content, groundwater, lake lands, and water content of snow on land and sea ice), nd static (pressure and density of the atmosphere and ocean, composition of the dry ir, salinity of the oceans, and the geometric boundaries and physical constants of the system). These properties are interconnected by the various physical processes such as precipitation, evaporation, infrared radiation, convection, advection, and turbulence, climate change...

In the example, pressure, temperature, and salinity data for the 36 hr prior to a user-triggered request is shown for station Tansy Point. Direct access to the actual data, either in numerical or graphical form, is available to authorized users. 

Effectiveness of dispersants is relatively easy to measure in the laboratory, however, there are many nuances in testing procedures [6]. One concern is that these tests are representative of real conditions. Since it is impossible to mimic all conditions directly, it is important to both consider the important factors such as sea energy and salinity while considering the laboratory tests as a form of screening or representative value, rather than a direct representation of what can be obtained in the field. Field measurements of dispersant effeetiveness are also fraught with difficulty because it is very difficult to measure the eoneentration of oil in the water column over wide distances in appreciably small times, because there are no commonly available oil slick thickness measures with which to assess the amount of oil remaining on the surfaee and because of the fact that the sub-surface oil often moves differently than the surface slick. Any field measurement at this time is best viewed as an estimate. Actual dispersant effectiveness is very difficult to assess for the same reasons. Effectiveness is indicated by the presence of a coffee-coloured dispersed-oil plume in the water column. This is visible from ships and aircraft. Lack of the coffee-coloured plume indicates no or very little effectiveness.

Fig. 4. A representation of hydrogeological environments where saline groundwater interfaces with recharge waters (after Olofsson 1994). Repository construction will introduce large amounts of recharge water below the salinity interface. The Aspo Groundwater Redox Chemistry Experiment showed that even a very soil-poor site like the island of Halo can provide organic carbon to the groundwater during repository construction. This result is expected for any repository site, and would be even more likely at sites with thicker soil cover, due to the greater pool of available carbon.
