Figure 1. Locations and names of three ocean-bottom seismographs (OBS) used to locate events and NOAA-PMEL’s bottom-pressure recorder (BPR). All located earthquakes are shown as green dots. Purple star indicates location of water-column anomaly as recorded during OBS deployments. Lower right figure shows outline of 1998 flow (Embley et al., 1999) compared(More)
With the proliferation of sensors it is becoming increasingly difficult to discover and access sensor data of interest. Currently, most researchers and sensor data users access data from sensors that they build by themselves or from known sensor network run by their friends; rarely do they try to find sensor data of interest that are maintained by other(More)
The Ocean Observatories Initiative (OOI) will implement ocean sensor networks covering a diversity of oceanic environments, ranging from the coastal to the deep ocean. Construction will begin in Fall 2009, with deployment phased over five years. The integrating feature of the OOI is a comprehensive Cyberinfrastructure (CI), whose design is based on(More)

F e d e r a t i o n The Ocean Acoustic Observatory Federation (OAOF) includes several laboratories and universities: the Institute of Geophysics and Planetary Physics (IGPP) and the Marine Physical Laboratory (MPL) at the Scripps Institution of Oceanography, the Pacific Meteorological and Environmental Laboratory (PMEL) of NOAA, the Naval Postgraduate(More)
Passive and active acoustic measurements are effective and unique approaches to ocean observation. Both approaches have techniques that are well-established and suitable for immediate deployment as part of an operational observing system. Many of these techniques exploit the remarkable ability of lowfrequency sounds to traverse great distances in the ocean.(More)
As sensor networks become denser and more widely deployed, the potential develops for interconnecting these networks to combine datasets, share technological solutions, and to conduct cross-disciplinary research and monitoring operations that rely on several signal domains simultaneously. To that end, the real-time observatories, applications and data(More)
Long-term observations of seismic activity and ground deformation at mid-ocean ridges and submarine volcanoes are required for an understanding of the spatial and temporal characteristics of magma transport and intrusion. To make precise Ž . records of tilt on the seafloor we have installed short baseline tiltmeters in six ocean bottom seismometers TILT-OBS(More)
