Theme 1. The Earth as a Complex System

Oral

The Ocean Observatories Initiative Cabled Array (OOI-CA) commenced operation in 2014 with two trunk cables extending offshore from the central Oregon Coast, that incorporate multiple science nodes which host approximately 140 commercial and custom oceanographic instruments. With an operational life of 25 years, this undersea network delivers ample power and real-time data acquisition to...

Theme 1. The Earth as a Complex System

Oral

Ambiguity in triangulation of events recorded on the IMS hydroacoustic network depend on the accuracy in knowing when these events occurred. Considering only the direct "line-of-sight" propagation path to a station, three stations are needed to pinpoint an event time. To overcome this requirement, consideration of additional signal features relating to the propagation characteristics can...
