Distribution of Dissolved Inorganic Carbon (DIC) and Its Related Parameters in Seawater of the North Yellow Sea and off the Qingdao Coast in October, 2007

Data on the distribution of dissolved inorganic carbon (DIC) were obtained from two cruises in the North Yellow Sea (NYS) and off the Qingdao Coast (QC) in October, 2007. Carbonate parameters were calculated. The concentrations of DIC are from 1.896-2.229 mmolL-1 in the NYS and from 1.939-2.032 mmolL-1 off the QC. In the southwest of the NYS, DIC in the upper layers decreases from the north of the SP (Shandong Peninsula) shelf to the center of the NYS; whereas in the lower layers DIC increases from the north of the SP shelf to the center of the NYS and South Yellow Sea. In the northeast of the NYS, DIC in all layers in- creases from the YR (Yalu River) estuary to the centre of the NYS. The distribution of DIC in NYS can be used as an indicator of Yellow Sea Cold Water Mass (YSCWM). Air-sea CO2 fluxes were calculated using three models and the results suggest that both the NYS and the QC waters are potential sources of atmospheric CO2 in October.

Stratigraphic Sequences and Their Implication in a Sea Area of the Western Yellow Sea Near Qingdao Coast During the Late Quaternary

An analysis of seismic data obtained through a cable route survey starting from the Qingdao coast to offshore has determined nine seismic units since Late Pleistocene. Correlation of the seismic data with Borehole Hj2 confirms three eustatic events that occurred during the Late Quaternary and formed terrestrial units 2, 5 and 7. At the low sea level stage, paleo rivers highly developed, eroded previous strata, formed paleo valley, and left materials.

Physical-biogeochemical interactions and potential effects on phytoplankton and Ulva prolifera in the coastal waters off Qingdao(Yellow Sea, China)

In recent years, the spectacular massive green tide of Ulva prolifera has become a recurrent phenomenon appearing every summer in the coastal waters off Qingdao(Yellow Sea, China), attracting the attention of scientists and local government. Based on multidisciplinary data collected during summer and winter, this study focuses on the hydrological characteristics and regional biogeochemical processes in coastal waters off Qingdao.The results show that the boundary of the Yellow Sea Cold Water Mass(YSCWM) can reach the Qingdao coastal region in summer and is locally raised to the upper layers to form coastal upwelling beyond tidal mixing and favorable wind. The regional summer upwelling off the Qingdao coast effectively enriches the nutrient concentrations in the upper water column and thus promotes growth of phytoplankton but reduces the dissolved oxygen(DO) concentration and pH value in the bottom. The regional summer upwelling off Qingdao coast may facilitate the growth and regional blooming of the U. prolifera that migrate to this region with the southerly wind.Additionally, the effects of the front on the aggregation of U. prolifera may be significant. In winter, the Yellow Sea Warm Current(YSWC) extends and spreads along the offshore region off the Subei Shoal towards the Qingdao coastal sea. This tongue-shaped warm water meets the cold coastal water off Qingdao, which leads to the formation of a physical front. As a consequence, remarkable fronts of nutrient and chlorophyll a(Chl a) also form between the shoreward warm water and the cold coastal water. This study increases the understanding of the interactions between the regional physical, chemical, and biological processes off the Qingdao coast.

THE FORMING-STORING ENVIRONMENT AND ABUNDANCE CONDITIONS OF QUATERNARY UNDERGROUND BRINE IN THE EMBAYED COAST OF QINGDAO

The discovery of useful brine resources in the embayed coastal zone of Qingdao is an important achievement in research on potential underground brine resources stored in Quatemary littoral facies in the North China coast. The Holocene transgression in this area provided the ancient seawater sources for forming brine. In spite of the unfarorable geological conditions (narrow littoral plain. shallow and thin Quatemary sedimentary strata) Qingdao’s embayed coast has deposition basins with bay-in-bay and weir dam ideal for gathering brine. The geologic structure of the littoral Quatemary deposition basin and hydrologic condition(deficient runoff) comprise favorable environment for the formation and abundance of underground brine.The embayed coast geomorphy controls the distribution of brine in patches that form small mineral zones in some parts. The brine aquifer whiment series formed under Quatemary littoral plain sedimentary and hydrogeologic environment are usually single phreatic ones. Part of the thick deposit areas consists of phreatic and poorly confined aquifers. Near the river mouth, there can someimes be brine aquifers interbeded with saline water ones. The basement of the brine ore deposits is comprised of Mesozoic rock formations. Underground brine is scattered almost all over the littoral plain and only in the larger plain’s area is the narrow saline water belt distributed beyond the brine zone. The structural features of the brine aquifer sediment series along the Jiaozhou Bay Coast are typical of those in the North China coast. We name it"Jiaozhou Bay Type" Its features are different from those of other brine aquifer sediment series such as "Laizhou Bay Type" and"Bohai Bay Type" in the littoral plain of the Bohai Sea.

Distribution and Provenance of Detrital Minerals in Southern Coast of Shandong Peninsula

Detrital minerals of 137 offshore and 22 river sediment samples collected from Qingdao coastal areas have been analyzed. Four mineral assemblage provinces can be classified by Q-mode cluster analysis. Factor analysis identifies two major factors that account for the total variability in most common minerals: 1) based on the relationship of quartz, hornblende, actinolite, micas, and authigenic pyrite, 41.55% of the variability is related to sediment sources; 2) based on the relationship of epidote, garnet, sphere, and ilmenite, 23.21% can be related to strong hydrodynamic conditions that control transport and sedimentation. By comparing mineral compositions of river waters in the study area, the following four mineral provenances can be identified. The Qingdao-Laoshan nearshore area has a quartz-feldspar-epidote-hornblende-limenite-limonite-sphene assemblage, which is largely attributed to relict sediment and coastal erosion. The Jimo-Haiyang nearshore area has a quartz-feldspar-hornblende-epidote-limonite-mica-actinolite assemblage, derived largely from the Wulong River and Rushan River, and is also affected by the Huanghe River, while the Qianliyan Island area in the deeper offshore area separated by a mud belt has a similar assemblage. The Haiyang-Rushan nearshore area has a quartz-feldspar-hornblende-epidote-micas-limonite assemblage, indicating multiple sources from the Rushan River, the Wulong River, the Huanghe River, and coastal erosion. The central area, located in an eddy center, has a mica-authigenic pyrite-hornblende-quartz-feldspar assemblage, indicating multiple sources dominated by Huanghe River distal sediments.

青岛近岸野生牡蛎及海滩沉积物中的微塑料季节性分布特征及其关联性

作为人类活动密集的城市近岸海洋环境中的微塑料污染日益突出,受到持续、广泛关注。为评估海洋微塑料污染带来的生态风险,在青岛近岸采集夏、秋、冬3个季节的牡蛎(Ostrea gigas tnunb)及海滩沉积物样品,分别采用碱性消解法、密度浮选法提取牡蛎体内和海滩沉积物中的微塑料,分析该区域内海洋微塑料的季节性分布特征以及牡蛎和沉积物中微塑料的关联性。结果显示:牡蛎体内与沉积物中微塑料丰度的季节性变化趋势具有一致性,表现为夏季>冬季>秋季;在3个季节中,牡蛎体内的微塑料丰度均显著高于沉积物中的丰度,是沉积物中的3~4倍;总体上,牡蛎体内和海滩沉积物中均以粒径<1 mm的纤维状微塑料为主,无明显的季节性变化;牡蛎体内与沉积物中微塑料的颜色总体上保持一致,以透明、蓝色为主;显微红外光谱显示,微塑料的聚合物种类有聚酯纤维、腈纶、人造丝、纤维素、聚丙烯-聚乙烯共聚物。基于牡蛎体内与沉积物中微塑料丰度随季节变化的一致性和微塑料物理特征上的相似性,建议将牡蛎作为青岛近岸海洋微塑料污染的指示生物。本研究可为青岛近岸海产品中微塑料的潜在风险评估及海洋微塑料污染的监测治理提供参考。
