Article
Indices based on branched glycerol dialkyl glycerol tetraethers (brGDGTs) have been useful in paleo-environmental reconstructions, although their applicability in river-estuarine sediments remains unclear. This study aims to investigate the correlation between brGDGT-based indices and modern environmental parameters, and to discuss possible impact...

This study investigates the reliability of phytolith assemblage analysis for characterizing subtropical vegetation and explores the potential for using these modern phytolith-vegetation relationships for paleoenvironmental interpretation in southeastern China. The samples were collected from five common subtropical vegetation communities in the Dai...
Article
Suspended particulate organic carbon (POC) and sedimentary total organic carbon (TOC) in coastal areas play critical roles in the global carbon cycle, yet sources and dynamics of coastal POC and TOC have been affected by various anthropogenic activities such as aquaculture, sewage discharge, dam construction and land reclamation. To better understa...
Article
Recently, glycerol dialkyl glycerol tetraethers (GDGTs) have been successfully used to identify different sources for organic-matter in the offshore and open ocean areas, while their applicability in the coastal areas remains unclear. This study was carried out to investigate the behavior of GDGTs and their applicability as indicators for organic-m...

Coal fires have been found to be a serious problem worldwide in coal mining reserves. Coal fires burn valuable coal reserves and lead to severe environmental degradation of the region. Moreover, coal fires can result in massive surface displacements due to the reduction in volume of the burning coal and can cause thermal effects in the adjacent roc...
Chapter
Though the Interferometric Synthetic Aperture Radar (InSAR) processing can produce Digital Elevation Model (DEM), the accuracy of the InSAR derived DEM need to be improved because of the impact of phase errors. To solve this problem, we propose a new approach which includes three steps. Firstly we estimate the baseline and utilize precise orbit dat...
Conference Paper
Persistent Scatterers for SAR Interferometry (PS-InSAR) tecnique allows monitoring the temporal evolution of a deformation phenomenon at millimeter level, via the generation of mean deformation velocity maps and displacement time series from a data set of acquired SAR images. However, the serious noises of multi-temporal SAR images make the selecti...
Conference Paper
It is well know that atmospheric phase screen(APS) effect in Small Baseline Subset (SBAS) D-InSAR processing to obtain ground deformation in long time series leads to additional interferometry phase and the unreliable result. To solve the problem above, MODIS product provide a mean to stimulate atmospheric field of SAR data for reducing the APS eff...
Article
Three Differential Synthetic Aperture Radar Interferometry (D-InSAR) methods are compared on the capability of obtaining land subsidence temporal data. These three methods including, Interferograms time-series stacking, Permanent Scatters D-InSAR(PS-InSAR) and Multi-Baseline D-InSAR are all base on interferometry phase spatial-temporal analysis to...
Conference Paper
By estimating the phase information of stable natural reflectors or permanent scatterers of a set of SAR images, Persistent Scatterers for SAR Interferometry (PSInSAR) can be used to obtain the land subsidence information at milimeter level while the serious noises of multi-temporal SAR images which make it difficult. In this study, we study the in...
Article
Decorrelation caused by temporal change and SAR imaging geometry prevents conventional SAR interferometry from monitoring land surface subsidence precisely. In addition, conventional methods don’t deal with phase delay which caused by atmosphere. It negatively influences the accuracy of Differential Synthetic Aperture Radar Interferometry (D-InSAR)...
