Ocean Bottom Seismometer: Design and Test of a Measurement System for Marine Seismology

The Ocean Bottom Seismometer (OBS) is a key instrument for the geophysical study of sea sub-bottom layers. At present, more reliable autonomous instruments capable of recording underwater for long periods of time and therefore handling large data storage are needed. This paper presents a new Ocean Bottom Seismometer designed to be used in long duration seismic surveys. Power consumption and noi...

Ocean-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...

Bottom 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...

Proton beam writing nanoprobe facility design and first test results

A second generation proton beamwriting line has been installed at the Centre for Ion BeamApplications at the National University of Singapore. This system features a high demagnification lens system based on compact OM52 lenses with reduced working distance. The system can operate in a variety of high demagnification configurations, including the spaced Oxford triplet and the double-crossover R...
