Abstract

Beneath 5000 m of water midway between Hawaii and California, the Hawaii-2 Observatory (H20) rests on the seafloor (Figure 1). Telemetry and power come to this pioneer, deep-ocean scientific observatory via a retired telephone cable, Hawaii-2, donated by AT&T to the Incorporated Research Institutions for Seismology (IRIS) Consortium for the benefit of the scientific community. H20 is the first Global Seismographic Network (GSN) station on the seafloor.With a suite of wet-mateable connectors on a junction box (j-box), H20 offers marine scientists a new opportunity to deploy and operate remote instrumentation in the middle of the ocean.
