Seismicity at the southern East Pacific Rise from recordings of an ocean bottom seismometer array
[1] Seismic data recorded by ocean bottom seismometers (OBSs) at the southern East Pacific Rise (SEPR) were analyzed to characterize seismicity at fast spreading mid-ocean ridges. An automated event detection algorithm based on pattern recognition was developed to identify earthquake-generated T phases. The waveform cross-correlation and least squares method was found to provide more robust est...
متن کاملTomographic image of crust and upper mantle off the Boso Peninsula using data from an ocean-bottom seismograph array
We determined the three-dimensional structure of the crust and upper mantle off the Boso Peninsula, Japan, by analyzing seismograms recorded by ocean-bottom seismometers and land stations between 2011 and 2013. We employed seismic tomography to determine the Pand S-wave velocity structures and earthquake locations simultaneously. The tomographic image shows that the mantle parts of the Pacific ...
متن کاملEffects of shallow-layer reverberation on measurement of teleseismic P-wave travel times for ocean bottom seismograph data
We conducted synthetic experiments to evaluate the effects of shallow-layer reverberation in oceanic regions on P-wave travel times measured by waveform cross-correlation. Time shift due to waveform distortion by the reverberation was estimated as a function of period. Reverberations in the crystalline crust advance the P-waves by a frequency-independent time shift of about 0.3 s in oceans. Sed...
متن کاملOcean-bottom krill sex
For the first time the entire sequence of the mating behaviour of Antarctic krill (Euphausia superba) in the wild is captured on underwater video. This footage also provides evidence that mating can take place near the seafloor at depths of 400-700 m. This observation challenges the generally accepted concept of the pelagic lifestyle of krill. The mating behaviour observed most closely resemble...
متن کاملBottom Stationed Ocean Profiler
The long term project goal is development and utilization of a bottom stationed autonomous ocean profiler for enhanced physical chemical and biological measurements in the coastal ocean.. The system is designed to allow bi-directional satellite communcation, user programmability, and data storage and transmission in near real-time. It is envisioned that deployments of large numbers of BSOP syst...
