  • 한국남동발전의 코어 발전소인 영흥화력발전소는 발전산업계에 있어 '강남스타일'로 통한다. 수도권 유일의 대단위 유연탄 발전소이며, 가장 최신의 발전설비들로 구성돼 있기 때문이다. 특히 지난해 상업운전을 개시한 영흥화력 5,6호기는 톡톡 튀는 신기술들이 요소요소에 접목되며 '혁신'의 아이콘으로 급부상했다. 국내 '최초'를 넘어 세계 '최고'의 친환경 명품 발전소로 발돋움 한 영흥화력 5,6호기를 구석구석 들여다봤다.

  • 인천시 옹진군 영흥면 영흥화력발전소 유휴지에 지난 2011년 영흥풍력 1단지가 설립되었다. 1단지는 정부의 시책에 따라 신재생에너지설비 발전의 시작으로 시험적 성격이 강했다면, 그로부터 2년후 추가로 지어진 영흥풍력 2단지는 국산 풍력발전의 도입과 성장이 어느 정도 진행되었음을 알리는 신호라고 할 수 있다.

  • The Yeongheungdo shipwreck was excavated in the sea of Seomeopbeol, Ongjin-gun, Incheon, Korea. Chemical characterization of timbers from the shipwreck occurred via maximum moisture content, chemical composition, FT-IR, solid state $^{13}C$ NMR, and XRD analyses. As maximum moisture content of the outer part of the timbers averaged 623%, a phenomenon in that lignin increased relatively, according to the decrease in cellulose, and the ash content increased, which is typical of waterlogged archaeological wood was shown. The results from the FT-IR and solid state $^{13}C$ NMR analyses showed that the cellulose band of the outer part had disappeared or had remarkably decreased. In addition, the bands assigned to lignin dramatically increased. However, regarding the inner part of the timbers, hemicellulose and some crystalline cellulose and amorphous cellulose bands decreased. Therefore, a large difference exists between the degradation levels of the outer and inner parts of the timbers of the Yeongheungdo shipwreck.

  • In order to reconstruct a benthic foodweb structure and assess the role of benthic microalgaes as a diet source for benthos, we analyzed the carbon and nitrogen stable isotopes of diverse benthos (bivalves, crustaceans, gastropods and fishes) and potential diets (particulate organic matter, sedimentary organic matter, benthic microalgae, seagrass, and macroalgaes) in the intertidal mudflat surrounding Yeongheung Island. The ${\delta}^{13}C$ values of the diets indicated wide ranges (- 26.5‰ to - 8.4‰) while benthos showed a small range of ${\delta}^{13}C$ values (-12.1‰ to - 17.8‰), although they were in the same range. Except for green algaes among the macroalgaes as well as sedimentary organic matter, ${\delta}^{15}N$ values of the diet candidates ($5.7{\pm}1.0$‰) were lighter in comparison to those of the benthos ($11.8{\pm}1.9$‰). Based on the ${\delta}^{13}C$ and ${\delta}^{15}N$ data, the benthos were classified into 3 groups, indicating a different diet and trophic position. But benthic microalgae is the most important diet source for all three benthos groups based on their stable isotope ratios, suggesting benthic microalgae should be a main diet to the intertidal ecosystem. Hence this study highlights that the biomass of benthic microalgae as biological resource should be evaluated for the management of the intertidal ecosystem of Yeongheung Island.

  • We investigated the various lithologies and zircon U-Pb ages of metasedimentary rocks from the Yeongheung-Seonjae-Daebu Islands, western Gyeonggi Massif, whose geologic and geochronologic features are poorly constrained in spite of their significance for tectonic interpretation. Major lithology consists of quartzites or meta-sandstones commonly alternating with semi-pelitic schists, together with lesser amounts of calcareous sandstones with matrix-supported quartzite clasts, calcareous schists, and pelitic schists. Pelitic schists uncommonly contain large porphyroblasts of garnet as well as quartz veins with large crystals of muscovite and andalusite or kyanite. SHRIMP U-Pb ages of detrital zircons from two analyzed metasandstones define four age populations: Neoarchean (~2.5 Ga), Paleoproterozoic (~2.0-1.5 Ga), Neoproterozoic (~1.1-0.7 Ga), and Early Paleozoic (~560-400 Ma). The youngest zircon ages are clustered at ~420 Ma. These results suggest that the deposition of meta-sandstones took place after the Silurian, possibly during the Devonian, and are analogous to those of the Taean Formation reported from the western part of the Gyeonggi Massif. Moreover, The age distribution patterns of detrital zircons and the Barrovian-type metamorphic facies of pelitic schists are similar to those reported from the Imjingang belt, suggesting that the Taean Formation likely corresponds to southwestward extension of the Imjingang Belt.
