MEASURING SURFACE DEFORMATION IN GLACIER RETREATED AREAS BASED ON PS-INSAR – GELADANDONG GLACIER AS A CASE STUDY
China Glacier retreat InSAR Paraglacial Slope Failure (PSF) Qinghai-Tibetan Plateau (QTP)
2018/5/15
Glaciers are retreating in many parts of the world as a result of global warming. Many researchers consider Qinghai-Tibetan Plateau as a reference for climate change by measuring glaciers retreat on t...
RECENT SEA LEVEL CHANGES IN THE BLACK SEA FROM SATELLITE GRAVITY AND ALTIMETER MESUREMENTS
Black Sea Sea Level Change Altimetry GRACE
2018/4/18
Sea level rise causes devastating effects on coastal habitats. For example, coastal erosion and saltwater intrusion are major threats for the Black Sea coasts. So, determining sea level changes in the...
针对苏门答腊岛西北海域大型海底滑坡,建立基于欧拉-欧拉多相流理论的滑坡模型,对滑坡体动态运动过程开展模拟反分析。通过与BING程序和解析模型结果对比,考虑土体分段软化后的多相流模型能够较好的重现该滑坡体的运动过程,能获得与实际海底滑坡相近的沉积形态和滑动距离。分析结果表明滑动首先从坡角较大处开始,并逐渐推动中、前部坡度较小处土体滑动;滑坡体整体启动后沿斜坡逐渐加速,当滑动至斜坡底部时端部峰值速度达...
Small Autonomous Aircraft for Economical Oceanographic Observations on a Wide Scale
Economical Oceanographic Observations Wide Scale
2015/8/19
A prototype aerosonde, which will fit comfortably on a desktop, and can be packed in two boxes sufficiently small to be taken as airline luggage, is shown in Figure 1. It will have a range of over 7,0...
The addition of molecular genetic tools to oceanographic toolboxes began with a pronounced emphasis on ribosomal RNAs (rRNAs). Already these molecules have been used to detect and examine the abundanc...
Blooms of the coccolithophore Emiliania huxleyi regionally act as an important source of dimethyl sulfide (DMS) and calcium carbonate and alter the optical properties of the surface mixed layer (Balch...
Oceans of Data: Oceanographic CD-ROMs for Research and Education
Oceanographic CD-ROMs Oceans
2015/8/14
Compact Disc-Read Only Memory (CD-ROM) technology has been used for a scant 7 years in oceanography, mainly for the distribution of data by the national archives of the National Oceanic and Atmospheri...
As humans we see and relate to the world around us in three dimensions, yet as scientists we usually attempt to understand our data by portraying it in visual form as a plot or a picture. These two-di...
The episodic nature of sedimentation on continental shelves is now widely accepted. Insight obtained in subdisciplines ranging from physical oceanography to seismology suggests that short duration, la...
Linking Sediment Transport and Stratigraphy on the Continental Shelf
Continental Shelf Transport and Stratigraphy
2015/8/13
The goal of the shelf sediment dynamics component of STRATAFORM is to link sediment transport processes active on the continental shelf to the formation and preservation of event beds in shelf sedimen...
Continental-Slope Sedimentation: The View from Northern California
Northern California Continental-Slope Sedimentation
2015/8/13
The slope portion of the STRATAFORM program sets out to establish a better understanding of the sedimentary processes important in developing the stratigraphic record of continental slopes over the pa...
Coastal Geological Oceanographers Provide the Fourth Dimension
Fourth Dimension Oceanographers
2015/8/13
The coastal ocean, defined here as waters covering the continental margin, has become an area of intense study. A driving impetus always has been to understand the complex oceanographic transitions be...
Geological Perturbations and Consequences of Extreme and Unexpected Phenomena in the Ocean
Geological Perturbations and Consequences Extreme and Unexpected Phenomena the Ocean
2015/8/5
Have you ever wondered how the ocean and seafloor react to rare but high energy extents, such as tsunamis, volcanic eruptions, extreme river floods, massive iceberg calving events, submarine slides an...
A Perfect Storm:Formation and Potential for Preservation of Storm Beds on the Continental Shelf
Perfect Storm Formation and Potential Storm Beds Continental Shelf
2015/8/5
Consider a coastal storm that mobilizes and transports enough sediment on the continental shelf to produce a distinctive deposit in the seabed that escapes significant reworking before it is buried by...
