Tonga is a seismologists’ paradise, and not just because of the white-sand beaches. The subduction zone off the east coast of the archipelago racks up more intermediate-depth and deep earthquakes than...
Source signature processing in deep water, Gulf of Mexico: comparison between deterministic deconvolution and phase conjugation
oversampling source signature deconvolution
2015/9/29
The Center for Marine Resources and Environmental Technology has been developing a new method to improve the resolution of high-resolution seismic profiling. To achieve this the source signature is re...

waterborne high-resolution seismic noise control
2015/9/29
Herein is presented an overview of high-resolution seismic profiling on water. Included are basic concepts and terminology as well as discussions of types of sources and receivers, field practice, dat...
Deep-water turbidites as Holocene earthquake proxies:the Cascadia subduction zone and Northern San Andreas Fault systems

New stratigraphic evidence from the Cascadia margin demonstrates that 13 earthquakes ruptured the margin from Vancouver Island to at least the California border following the catastrophic eruption of ...
Relation between electric properties and water saturation for hematitic sandstone with frequency
Electric properties complex conductivity frequency
2015/9/1
This paper focuses on the effect of water saturation on A. C. electrical conductivity and dielectric constant of
fully and partially saturated hematitic sandstone sample (Aswan area, Egypt). The satu...
Multichannel seismic imaging of ocean water column features is a new interdisciplinary study that may become an accepted oceanographic tool in coming years. We now know that reflectors are associated ...
During HERMES cruises in spring 2006 and 2007 to a cold-water
coral (CWC) reef at the border between Norway and Sweden, we studied effects of
the reef on the quality (C/N ratio) of suspended parti...
It was a bit like making a CT scan of a patient’s head and finding he had very little brain or making a PET scan of a dead fish and seeing hot spots of oxygen consumption. Scientists making seismic im...
Water-Level Changes in Shallow Wells Before and After the 1999 İzmit and Düzce Earthquakes and Comparison with Long-Term Water-Level Observations (1999–2004), NW Turkey

2009/7/7
It is well known that earthquakes cause hydrological changes, such as drying or flooding of water wells, fluctuations in ground-water levels in wells, changes in water quality, and formation of new sp...
