In 2014–2015, nine enclosures built of stone slabs were excavated at Altynkazgan on the Mangyshlak Peninsula, Republic of Kazakhstan. Inside them, remains of offering ceremonies were found: vessels dug into the ground, altars made of limestone blocks, and pits for offerings. In one of these, we found a richly decorated bridle, in another, a belt set of inlaid golden plaques, and in the third, remains of a saddle (silver plates and other items). The entire assemblage has numerous parallels among the 5th and 6th century fi nds from the northern Black Sea area, North Caucasus, and the Volga basin. Ritual burial of a “golden” belt, a bridle, and a ceremonial saddle indicate an advanced cult that included offerings of prestigious belongings of a horseman. These rituals were introduced by Iranian-speaking nomads who had migrated to the eastern Caspian region during the Hunnic raids to Iran in the 5th century. At that time, owing to the regressive phase of the Caspian Sea, the semi-desert northern Caspian coast was connected with Mangyshlak by a land bridge. Our hypotheses are supported by both historical records and modern geomorphological studies of the Caspian Sea.

Abstract The oceans and seas have huge areas of the planet. The ecosystem services that can be obtained from these resources are very diverse and with potential one of these sources is wind power. As a result, the Caspian Sea is widespread with a fragile ecosystem. Which seems to be the right choice for the development of this industry. Therefore, for modeling the wind energy of the Caspian Sea, the data from the ERA-Intrem for 1980 to 2015 combined with QuickScat and RapidScat remote sensing data. The modeling results showed a power density of 173 W/m2, concentration density in the series process showed that 67% of the Caspian Sea area has a decreasing trend, the rate of this sea change for the entire period from 1980 to 2015 was 2.1 W/m2. These changes in the northern part of the Caspian Sea have a higher rate than other parts. The sea is affected by climate change.

The article analyses possible interests, attitudes and activities of the major actors in the ‘natural gas supply game’ in Europe after 1990: Russia/Gazprom, alternative suppliers like countries in the Caspian Sea area, the main consumers of gas and transit countries. It stresses that behaviour of the actors depends on the changing international political and economic situation and conditions in individual countries. Special attention is paid to pipeline projects: Nord Stream, South Stream and Nabucco, and reactions to them, such as building a LGN terminal at Świnoujście (Poland), North-South (Baltic-Adriatic) energy corridor and the Polish-Russian gas contract of 2010.
