Buoy stations

The total number of moored buoy stations in the Black Sea seems to exceed 1,000. Meanwhile, most of these observations were confidential and unavailable for a reliable quantitative generahzation. For example, the numerous autonomous instrumental measurements generahzed in the well-known study [7] resulted only in a rather conceptual schematic of the BSGC that, as has been mentioned above, almost does not differ from those compiled in the 1930s to 1940s. 

When considering water circulation, quantitative and qualitative generalizations and a comparison of the the results of the studies of the Black Sea currents performed using modern observation techniques (autonomous buoys stations, shipborne acoustic measurements, drifter and altimetric satellite observations) with different types of hydrodynamic models were presented. The horizontal and vertical structure of the general water circulation in the Black Sea is shown, together with its seasonal and interannual variabilities. The principal mechanisms for the current formation under external hydro- and thermodynamical forcing are discussed.

In the early 1970s, several temporary buoy stations were installed in the shallow western Baltic Sea off the coast of Mecklenburg-Western Pomerania (cf. Table 3.2) to improve technical details for installation and running of buoy stations (Muller, 1974). These stations were equipped with mechanical current meters of the LSK type or of the Russian current meter Alexejev and with photothermographs for measuring temperature (Franck, 1976). 

Using the same inflow event, Francke and Hupfer (1980) studied ciurent, wind, sea level, and salinity conditions in the Darss Sill area. On the basis of measurements at the permanent buoy station at the Darss Sill, they analyzed currents in the surface and bottom layers in December 1975 and January 1976. Lass and Schwabe (1990) examined the dynamics of the... 

Applications for the lithium-sulphur dioxide reserve systems include underwater mine batteries and (active batteries) memory protection, manpack communicarions, life-support equipment, sonobuoys, space probes, missiles, mines, security systems, data buoys/stations, weather sondes and electronic counter measures. The non-reserve (active) systems are used for covert sensors, memory protection and weather sondes. 

A third aspect of flow cytometry (known sometimes simply with the acronym for fluorescence-activated cell sorter, FACS, or even more familiarly as just flow) that distinguishes it from many other techniques is the way in which its wide and increasing usefulness has continued to surprise even those who consider themselves experts. What began as a clever technique for looking at a very limited range of problems is now being used in universities, in hospitals, within industry, at marine stations, on submersible buoys, and on board ships plans have existed for use on board space ships as well. The applications of flow cytometry have proliferated (and continue to proliferate) rapidly both in the direction of theoretical science, with... 

TRITON system is being enhanced by allocation of new buoys (e.g., along the equator in the Indian Ocean). Together with data obtained using BATS, HOT, OFP, and other components of the autonomous anchored stations to monitor different basins of the World Ocean, an information database is being accumulated for more reliable estimation of GMNSS input parameters. 

Sediment sampling of the seven stations using the CS equipment was carried out by running transects with the survey vessel parallel to, and as close as possible to, the marker buoys. The CS underwater seafloor sediment sampler was pulled at a speed of three knots and, when abreast of each buoy, the sediment collected was recorded as being from that station. The sediment wafers prepared aboard ship from the collected slurries were immediately analyzed by XRF for three elements (Mn, Fe, and Ti) and were stored for further land-based analyses of other elements. A comparison of the elemental content of the sediments collected from the seven stations by box coring and with the use of the CS equipment constituted the basis for ground-truth evaluation of the CS system. 

Another strontium isotope, Sr-90, is highly radioactive, with a half-life of 29 years. Strontium 90 has been used as a power source in weather stations and buoys. 

The lack of agreement in results, such as those in Fig. 4, has stimulated considerable discussion in the gas exchange community about reasons for observed differences (e. g. [26]). While wind speed is routinely measured by ships, met buoys, and at shore stations, and can be estimated from satellite scatterometer measurements, it now appears clear that wind speed alone is not sufficient as a predictor of gas exchange and that other variables such as fetch, surface active materials, bubbles, and time and space scales of measurements are all important. 

There are very large numbers of surface observations for winds, temperature, humidity, precipitation, cloud types and covers, radiation, etc., over the continents and islands. Matty of the surface stations report at least twice a day at 00 and 12 UTC, but some of them report every hour. Other importaut surface observations come from traveling cotttmercial ships that provide atmospheric arrd oceartic data at synoptic times. In addition, 100 or more drifting buoys gather atmospheric and oceanic data. 

After the development of the radio, a position could be determined by triangulating radio stations with known positions. With the development of radar, images of known landmasses or buoys could be used for triangulation.

In practice, the suitability of a reaction system is determined by the kinetics of the reaction, which depends on temperature, pressure of gases, electrode polarization, surface area of electrodes, and presence of a catalyst. A fuel cell that is thermodynamically and kinetically feasible must be considered from an econonuc viewpoint before it is accepted. Thus, since hydrogen, hydrazine, and methanol are too expensive for general application, their use in fuel cells has been limited to special cases. Hydrogen has been used for fuel cells in satellites and space vehicles, in which reliability and lightness are more important than cost. Hydrazine fuel cells have been used in portable-radio power supplies for the United States Army because of their truly silent operation. Methanol fuel cells have been used to power navigation buoys and remote alpine television repeater stations because such power systems are comparatively free from maintenance problems over periods of a year or more. The polarization at the electrodes of a fuel cell is the most important single factor that limits the usefulness of the cell. The various polarization characteristics for a typical fuel cell are plotted separately as a function of current density in Fig. 9.11.
