Historical development in soil micromorphological imaging     

A.R.Mermut 《山地科学学报》2009,6(2):107-112

The book ＂micropedolog＂ by Kubieana and a large number of publications has induced many people to practice soil micromorphology. Quantification of the soil fabric and its components was a major challenge. The use of the image analyses in soil science was a breakthrough. Attempts to make soil thin sections go back to the beginning of the 2oth century. Microscopic techniques and recently high resolution electron microscope and use of computer assisted imaging techniques enabled the in vitro study of soils in three dimensional levels. It is now possible to store and process massive amounts of data. Micro- morphological concepts and techniques are applied in paleopedological, ecological, and archaeological studies. The aim of this work was to examine soil micromorphological imaging in historical perspective.  相似文献

记者22日从国土资源部广州海洋地质调查局获悉,我国“海洋四号”科考船近日采用新研制的“气密性孔隙水原位采样系统”,首次在南海中央海盆4000多米深水水域海底成功获取孔隙水样品。这标志着我国对可燃冰的深海探测技术又取得了新的突破。“气密性孔隙水原位采样系统”由多个高强度抗腐蚀金属材料气密容器纵向排列,通过水下计算机实现对孔隙水采样的全自动监控和采集。该系统近日搭载于“海洋四号”科考船进行海上试验,其最大工作水深超过4000m,沉积物采样深度大于5m,可同时采集11个层位的孔隙水,系统仅在海底停留5分钟,每个层位采水量皆超过100mL,共采集孔隙水1198mL,  相似文献   

BTEX anomalies used as indicators of submarine oil and gas reservoirs   总被引：1，自引：0，他引：1

It is a conventional method for petroleum prospecting to generally use paraffin hydrocarbon as basic indexes of oil and gas. This conventional geochemical technology, however, shows some limits in the prospecting as paraffin is vulnerable to influences from human and biologic activities. Consequently, BTEX (short for benzene, toluene, ethyl benzene and xylem, which are direct biomarkers) among aromatic hydrocarbon series has been taken into account for the oil and gas prediction. Domestic and foreign study results demonstrate that BTEX is hardly disturbed and can well indicate oil and gas reservoirs. Based on measured data from a South China Sea area, the present authors have used self-developed visual assessment software for petroleum prospecting has been used to process data, strip background anomalies, and outline significant BTEX anomalies. By comparison with stratigraphic profiles of the target area, it is confirmed that BTEX is a good indication of marine oil and gas during the petroleum prospecting.  相似文献   

Analyses of the long-term salinity variability in the Bohai Sea and the northern Huanghai(Yellow) Sea     

YUHuaming  BAOXianwen  L&#;Cuilan  CHENXu''en  KUANGLiang 《海洋学报(英文版)》2009,28(5):1-8

Based on the comprehensive collection of the field observed salinity of the Bohai Sea (BHS) and the northern Huanghai Sea (NHS) from the 1950s to the present,the patterns of 10-years-averaged salinity at the different layers in the recent five decades (the 1950s,the 1960s,the 1970s,the 1980s and the 1990s) are obtained by the spatial-temporal interpolation technique with the scrupulous data quality control in this study.Then,by combining the spatial-temporal interpolation technique with successive correction method,the annual distributions of salinity both in the BHS and in the NHS are obtained as well.The data analyses indicate that the overall salinity in the BHS and the NHS increases from the 1960s till the present,with the increase of annual mean salinity of 0.04 psu from the 1950s,and the maximum increase rate of salinity is about 0.14 psu/a in the Bohai Bay.The high salinity tongue extended significantly from the NHS into the BHS.The intensified eastern wind field is related to the western intrusion of the NHS warm current,which probably leads to the moving forward of the high salinity water mass into the BHS.However,it is rather different from the salinity distribution characteristics between the 1950s and the 1960s.The extensive precipitation in the 1960s could lead to an increase in the discharge of the Huanghe River,which might result in the decrease of salinity in the BHS.But the salinity isoline of 32 in the NHS still extended significantly into the BHS in the 1960s.Since the 1980s,the patterns of salinity distribution have changed thoroughly.The salinity in the central area of the BHS was low,while the salinity in the Bohai Bay and the Liaodong Bay was higher than the other regions with its horizontal salinity gradient decreasing in the 1980s.The Empirical Orthogonal Function Analysis (EOF) is also conducted to study the interannual salinity variability of the BHS and the NHS.The correlation coefficient between the time coefficient series of the main mode and the Huanghe River discharge can reach -64.57%.It can be concluded that salinity variation of the BHS and the NHS has strong negative correlation with the Huanghe River discharge.  相似文献   

The application of geographic information technology to coastal geomorphology     

GUOWei  LIShuheng  ZHUDakui 《海洋学报(英文版)》2009,28(5):49-57

With the development of modern oceanic observation technologies,coastal survey data have been experiencing a substantial growth.The integration management of the data from different disciplines,different sources and different formats has become a major research field in coastal geomorphology by using Geographic Information System (GIS).This paper puts forward a new methodology framework of GIS techniques in coastal ocean geomorphology,including data acquisition,process,analysis,and representation.It focuses on some major GIS techniques to study the land-ocean interaction mechanism,such as spatial analysis,submarine topography model and three-dimension (3D) visualization,and apply its result to coastal urban planning,harbor site selection and geomorphology environment about coral reef and islands on the continental shelf.The case studies cover the whole coastal ocean to serve the social community,economical development and diplomatic rights for decision-making all round in the coastal zone.The research shows clearly that the application of coastal multi-source geospatial platform has changed the traditional coastal geomorphology science dramatically from its research scope,fields and methods,however,as made clear in this paper,extracting accurate information from remote sensing data and GIS databases for coastal geomorphological applications is a nontrivial challenge that requires the combined knowledge and skills of information scientists and geomorphologists.  相似文献

HUANGYu  WUHonghai  HEYe  YAOShengchu 《海洋学报(英文版)》2009,28(5):112-115

It is a lot limitations to survey and design waterway by the CAD technique,due to timely variation of hydrology and ecology in the complicated estuary area,such as Changjing River estuary.In this paper,the advantages of GIS technique is applied to manage and process the multi kind,multi scale and multi time hydrographic parameters,including water depth,current velocity,tidal,waves,wind speed,temperature and salinity etc.,also to deal with different projection,different scale charts.Meanwhile,in the paper,combination techniques of GIS and CAD has been developed for unification of the charts for efficient management,two-way automatic carts conversion between GIS and CAD,automatic cutting and assemble of a number of Charts,flight path of the projection of spatial data and coordinate transformation.This new technique has been applied to survey and design waterway of Changing River estuary.The result shows that the combination technology of GIS and CAD has application potentiality in the waterway survey and design.  相似文献
