Еволюція топоформанта -щина в слов’янських мовах та його рефлекси в реґіональній історичній ойконімії

У статті автор на широкому географічно-історичному тлі простежує еволюцію топоформанта -щина в слов'янській топонімії детально аналізує рефлекси цього суфікса в реґіональній історичній ойконімії на прикладі дев'яти назв (і 12-ти мікроойконімних варіантів) населених пунктів Галицької та Львівської земель Руського воєводства із подальшим встановленням їхньої етимологи.В статье автор на широком географическо-историческом фоне прослеживает эволюцию топонимического форманта -щина в славянской топонимии детально анализирует рефлексы этого суффикса в региональной исторической ойконимии на примере девяти названий (с 12-ю микроойконимными вариантами) населенных пунктов Галицкой и Львовской земель Русского воеводства с последующим установлением их этимологии.The author traces the evolution of topoformant -schyna on the basis of historical and geographical studies in Slavic Toponymy. Reflexes of the suffix are analyzed in regional historical oykonymy in 12 toponyms (and their 12 microokonymic variants) of villages and towns of Halych and Lviv Lands of Ruske Woyewodstwo. Their etymology is also analysed

Expressions of shallow gas in the Netherlands North Sea

Surface and sub-surface expressions of shallow gas in the Netherlands part of the southern North Sea are described, using standard E&P 2D and 3D seismic surveys, as well as higher frequency acoustic surveys. Surface expressions observed are pockmarks, which are geomorphologic features at the seabed indicative for venting of gas, and cemented sandstones. The sub-surface expressions found comprise both phenomena indicating efficient trapping of gas in reservoir sands, such as shallow bright spots and flat spots, and phenomena, which are indications of migration or leakage to the seabed. We refer to the latter as 'seismic anomalies indicating leakage'. These anomalies include gas chimneys or seismic chimneys. All chimneys found in the area have in common, that they belong to a seepage style, which is called 'small and localised'. Much of this seepage is situated over salt domes, with the accompanying normal fault above the domes acting as pathways for the gas or fluids. Although there is admixture of biogenic gas, it is believed that many of the features observed relate to thermo-genic gas. --- See newer version: Schroot, B.M., Klaver, G.T. & Schüttenhelm, R.T.E.

Surface and subsurface expressions of gas seepage to the seabed – examples from the Southern North Sea

Expressions of gas seepage observable within North Sea seismic and acoustic data include seabed pockmarks, seepage plumes in the water column, acoustic blanking, shallow enhanced reflectors, and shallow seismic chimneys. Three areas were selected for a marine survey i
