Time Drift of Ocean Bottom Seismometers (obs)
During the past decades, Ocean Bottom Seismometers (OBS) have played a key role in permanent seismic activity monitoring at sea as well as allowing a better understating of the earth interior. Data collected by the instrument can provide information on the ocean bottom sub-layers down to a depth of 40 km beneath the ocean floor. The accuracy of the results directly depends on the time drift of ...

متن کاملDetermining the orientations of ocean bottom seismometers using ambient noise correlation
[1] The cross-correlation of multicomponent ambient seismic noise can reveal both the velocity and polarization of surface waves propagating between pairs of stations. We explore this property to develop a novel method for determining the horizontal orientation of ocean bottom seismometers (OBS) by analyzing the polarization of Rayleigh waves retrieved from ambient noise crosscorrelation. We de...
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...
