River shoals

Matlock in Derbyshire (Pentecost, 1999). Another remarkable form, documented only from the mountainous regions of China are the river shoals (Figure 6.5). These consist of large shallow sheets of turbulent water between travertine-dammed lakes, beneath which the tufa builds evenly around a bryophyte and algal biofilm.

In 1703-1704 in Amsterdam the Atlas of the Don River, Azov and Black Seas prepared by Admiral K. Kruis was published. It comprised descriptions and 17 maps. The maps were made by the cartographic materials collected during sea voyages of the ship Krepost in 1699. The maps showed depths, shoals, inflowing rivers, harbors, and cities. All maps were hand-painted. This atlas is considered the first significant work of Russia cartography. 

These changes may be related to the two warm winters that occurred in 1998 and 1999, which could affect the balance between input of freshwater from the rivers and saline water from the Bosporus and the winter formation of the oxygen-rich CIL. These years are remarkable for the increase of the Sea surface temperature (Fig. 8), increase of temperature in the core of the CIL [82,85-87], and shoaling of the CIL in the density field [48]. All these events can be connected with the weather condition oscillations, as follows from North Atlantic oscillation (NAO) index behavior (Fig. 8). 

During this period, Wilson Dam was built on the Tennessee River at Muscle Shoals, Alabama, to furnish the power needed for the production of synthetic ammonia by the Haber process. This project was undertaken to insure a domestic source of nitrates for producing munitions and fertilizers. When the Tennessee Valley Authority was organized in 1933, the dam and facilities became a part of the Authority and thus the National Fertilizer Development Center at Muscle Shoals was born. 

Figure 6.5 Pearl Shoal, Juizhaigou, Sichuan, China. Water from the Beishui River forms an extensive riffle over a growing travertine surface covered in a biofilm of algae and bryophytes before plunging over a large prograding cascade (Pearl Falls). Upstream is a large travertine-dammed lake.

The biological decomposition of sulphates occurring on the one hand on the earth s surface and, on the other hand, in the mouths of rivers and shoals of seas and oceans. In the course of this process, some microorganisms release H2S, which enters into the atmosphere. In the air, H2S is oxidized very rapidly to SO3, and H2SO4 is produced in the presence of the air humidity. Sulphuric acid further reacts with components of the polluted atmosphere, producing sulphates. Last, solid sulphate particles fall back to the earth s surface by the action of gravity or atmospheric precipitations.

Changxing Island is a hilly bedrock island, so sediment supply from the island is very limit. Fuzhou River is the longest river nearby and flow into Fuzhou Bay with annual runoff of 263 million m. The river discharge sediment mainly concentrated at river mouth in the north of Changxing Island and cannot transport to Majia Shoal sea area.
